Controol
Focus on what you can spend, not what you already did.
I’m testing something new in my app Controol: an automatic weekly email recap (for PRO users only) sent every Monday morning, showing everything you did during the past week.
It’s like a personal finance newsletter that includes:
Your recorded income
Total spending
Average daily spending
Average daily income
Your highest income and expense
And an AI-generated financial tip for the week
For example, one of the AI tips might look like this:
“Your biggest expense was dining out. Try cooking at home at least 3 times this week to save money without sacrificing your lifestyle.”
But now I’m wondering:
As a user, what would you prefer?
Weekly or monthly financial recap?
I’m building Controol, a minimalist app to help people spend without guilt by knowing exactly how much they can afford — not just tracking what they already spent.
Most finance apps focus on graphs and past activity. My vision with Controol is different:
✅ You enter your income, and it’s automatically split into “boxes” based on percentages you define (like the 50/30/20 method).
✅ You register your expenses, and the app tells you if that expense fits the available amount in the right box.
✅ You don’t micromanage categories — you manage limits, clearly.
But what I’m most excited about:
🧠 AI chat built into the app. You can ask things like:
"Can I spend $80 on dinner today?"
"How much have I spent on non-essentials this week?"
"Are my percentages balanced based on my income?"
It gives quick, human-style answers. No dashboards. No friction.
🗣️ So I’m curious:
If you were to use a finance app, what would you really want from it?
What’s something that’s always frustrated you with others?
Whether you’re a builder or a user — I’d love to hear your honest thoughts.

Love this share. Can you plug it into real time banking apps using open banking (or similar) to also help budget?
-
2
Thanks a lot! That’s a great question.
Right now, Controol works manually (you input your income), which keeps it simple and flexible.-

Just for insight, I use a spreadsheet to track my expenses. It has monthly bills etc and I update it every other day when a bill comes out. It's a real pain!
-
1
I totally get you — I used to do the same with a spreadsheet. It works, but it’s a pain 😅
That’s actually why I built Controol — just to have it on my home screen, open it, and quickly log something.
But honestly, what mattered most to me was knowing how much I could spend, not how much I had spent.You could give it a try and maybe even share some feedback 😄

This is a super fresh take on personal finance — love the focus on spending clarity instead of just tracking the past. The built-in AI chat is a game changer! 🔥
One thing that might be cool to add: a multi-currency converter. Would be super helpful for people traveling or managing different currencies — helps them stick to their limits wherever they are.
-
1
Thank you so much — love that you captured the vision behind Controol so well!
The AI chat is definitely a key part of the experience, and it’s great to hear it resonates.
And that’s a brilliant idea! A multi-currency converter would really help for international users — especially digital nomads or frequent travelers. Noted for the roadmap!

Love the vision behind Controol—especially the AI assistant concept. Super smart! Since you're building something minimalist and user-focused, a clean and thoughtful logo can really boost first impressions and trust. I specialize in modern logo design for early-stage startups and would love to offer a few ideas if you're exploring branding soon. Happy to share examples if you're interested!
-
1
Thanks a lot — really appreciate your kind words about Controol!
I’ve been keeping everything super minimal (even the branding), but I agree that a thoughtful logo can go a long way.
I’d definitely be curious to see some examples of your work — feel free to DM me or drop a link!
-
1
Thank you so much! I’d be happy to share some logo samples with you.
If you don’t mind, could you please share your email or Gmail? I’ll send a few tailored examples of my recent work for Controol’s vibe.
Looking forward to hearing from you!

Thanks so much! I really appreciate that.
I tried to keep the UI as clean and minimal as possible — glad it stood out!
Let me know if you end up trying it, I’d love to hear your thoughts.

From a personal finance app, I expect budgeting tools, expense tracking, bill reminders, financial goal setting, investment insights, data security, and an easy-to-use interface that helps build smarter money habits.
-
1
Thanks a lot for sharing that — super helpful to hear what users actually want.
Controol right now is laser-focused on helping people know how much they can safely spend — through customizable "boxes" and AI-powered suggestions. It’s very minimalist by design, to reduce overwhelm.
But I love that list, especially financial goals and smart reminders. I’ll definitely consider adding more around that as the app evolves.
-
-
1
This is great idea. definitely this tool will be very helpful to someone who really in pain. Include AI is an amazing thing.
-
1
Thank you so much! 🙏
That’s exactly what I hoped for — to help people who feel overwhelmed or anxious about money get some peace of mind and clarity.And the AI helps simplify things even more — so they don’t have to figure it all out alone.
-

I think this sounds like a great idea. I love the AI aspect. One thing that always get me to stop using budgeting apps is that every month seems to have outliers. A medical bill, a home repair, a one time purchase. Other things like mortgage, utilities, auto loans, insurance also aren’t things I can control on a monthly basis. I think setting a budget for just food, entertainment and shopping/services would be all I’d want to see. Let us exclude categories and purchases.
-
1
Thanks again! And I totally get what you mean about fixed expenses.
In Controol, you're actually free to create your own “boxes” — so if you only want to track things like food, entertainment, and shopping, you can just set up boxes for those and ignore the rest.
There’s no need to include your rent, insurance, or other fixed stuff if it’s not helpful for you. You stay focused only on what you can actually adjust.
-

This is such a smart angle, love the idea of an AI-powered budgeting tool that actually gives real-time, human-style feedback. Feels way more intuitive than traditional finance apps. Excited to see where you take this!
-
1
Thanks a lot! That means so much. I really wanted Controol to feel more like a conversation than a spreadsheet — glad that came through! Can’t wait to keep improving it and pushing the AI side even further.

Hi @Maxi Carreras, congrats on your project!
To answer your question, what I find frustrating is having to log every single expense manually — especially when one receipt includes items from different categories.
Hope that helps!-
1
Thanks so much! I actually feel the same way — that’s one of the reasons why I built Controol. The app doesn’t focus on what you spent or force you to log every single receipt. Instead, you just input the total, and it helps you understand how much you can safely spend next time without going over budget. That’s the part that really matters.
-
Four months ago I started building Controol because I was tired of feeling anxious every time I spent money — even when I could afford it.
Most budgeting tools made me feel guilty instead of clear. I wanted the opposite.
So I built something around a simple idea:
Know what you can spend, not what you already did.
No team.
No pre-launch email list.
No ad spend.
Just shipping a solution to my own pain.
Yesterday I launched it on Product Hunt... and it reached the Top 5 of the day.
The feedback has been incredible. People resonate with the mindset shift.
If you're building something and wondering if it’s even worth launching without a following — this is your sign. Do it anyway. You don’t need perfect conditions to start.
Happy to answer anything about the launch or product if it helps! 💬

Wow, this is amazing truly inspiring! Keep building awesome stuff 💯😎.
I’ve got an SaaS idea I’m super excited about, but I’m new to this space and not sure where to start.
If anyone’s open to pointing me in the right direction or sharing advice, I’d really appreciate it.
-

Thank you so much! I really appreciate the kind words.
And congrats on having a SaaS idea you’re excited about — that’s already a huge step!
Honestly, I was also figuring it out as I went. My biggest advice:
Start small
Validate fast
Talk to people
Don’t overthink it — just build and improve
-

Thank you so so much for this tips. Is there any way to reach out to you later. Incase I have more questions you might be willing to assist me with? Like socials?

That's insane!

That's an interesting approach to personal finance app! For me, such personal finance app never really worked for me because I find it a hassle to enter my expenses daily and sometimes, I forget to key them in, and the numbers start to go haywire. Maybe you could find a solution for that?
-
1
Thanks! I totally get that — manually logging every expense can be a hassle.
But with Controol, that’s not really the main focus.
You don’t need to track every single expense. Just adding a rough total at the end of your day is more than enough.
Why? Because the app is built around knowing how much you can spend, not obsessing over how much you already did.
-
-

that's awesome, any tips on your MVP development state to manage to be ranked #5?
-
1
Thanks a lot! 🙌
Honestly, here’s what worked for me with the MVP:
Keep the core idea super clear. Controol wasn’t trying to do everything — just help people know how much they can safely spend.
Simplify the UX as much as possible. One main screen, zero friction, no fancy dashboards.
Launch fast, explain with clarity. I shared the story behind why I built it and not just what it does.
Also… being active on launch day helped! I engaged with every comment and tried to genuinely connect. Product Hunt loves human stories, not just features.
Let me know if you’re working on something too — happy to take a look!

I've never used personal finance apps before, but your post really caught my attention and inspired me. I'd love to try your app. If it works as described, it sounds like a huge success. However, I had some trouble figuring out how to get the app - I couldn't find it on popular platforms like the App Store or Google Play. Additionally, when I tried to sign up through the website on mobile (I’m using Safari), some pages and icons didn’t load properly. Any advice on how I can get started?
-
1
Thanks so much — that’s amazing to hear and I really appreciate you taking the time to share this!
Right now, Controol is a web app, so it’s not on the App Store or Google Play yet.
But you can use it on mobile by going to https://controol.app, and if you’re on iOS, you can even add it to your home screen as a PWA for a more app-like experience.
It’s actually the first time someone reports issues like that — the web app usually works smoothly 🫶
Still, I’ll double-check things on Safari just in case.
-
1
Additionally, I've been using Firefox as my default browser for quite some time, but it takes forever to load. When I tried a different browser, it worked fine. It's not practical to keep it on my home screen since every time I want to use it, it redirects to Firefox and the same issue occurs.
-
1
Thanks so much for the feedback! I hadn’t run into that issue with Firefox before — and that’s definitely not the experience I want anyone to have.
It seems like Firefox is struggling with how it handles PWAs or web apps from the home screen. I’ll dig into this and see if there’s anything I can optimize on my end.
In the meantime, if you're okay switching the default browser temporarily to Chrome or Safari, the PWA works much smoother that way. Really appreciate you sharing this!

That is cool. Getting into the top 5 on PH is not easy without paying a group of people to promote it. Looks like you have solved a real issue.

Thanks! That means a lot.
Yeah — no paid group, no audience, just tried to share the real pain point and be super honest about it.
Glad it resonated, and I’ll keep building from here!

This is incredible — you didn’t just build something, you solved a real pain point that so many of us feel but struggle to express. What truly struck me is the mindset you brought into building it — that’s the biggest takeaway for me. Thank you for sharing this, it genuinely inspired me.
-

Wow, thank you so much — that truly means a lot.
I built Controol to solve a feeling I had for years, so knowing that it resonates with others is everything.
Really grateful it inspired you — that makes the whole journey worth it.

Love the mindset behind this
“know what you can spend”
flips the usual guilt-driven approach on its head.
Congrats on the PH success!
What was most helpful in getting those early upvotes and traction without an audience?-
1
Thanks so much — really appreciate that!
That mindset shift is exactly what I wanted to bring into the space.
As for early traction, honestly:
I shared my story in a few places like Indie Hackers and Reddit,
replied to every comment genuinely,
and focused on clarity and real pain points in the PH post.
-
-
1
Congrats! I saw you guys on there yesterday. Also working on launching my app on PH soon, very excited :)
-

This is incredibly inspiring, especially how clearly you framed the pain point, and just shipped without a big list, team, or spend. Congrats on the PH success, well deserved.
Curious: what was the hardest part of building Controol solo? Was it product clarity, motivation, feedback loops… or something else that doesn’t get talked about enough?
I’m building something as well and really resonate with the “do it anyway” message.
-
1
Thank you so much — that really means a lot 🙌
Honestly, the hardest part of building Controol solo wasn’t technical… it was staying confident when no one was watching.
No one to bounce ideas off. No users yet. Just me, second-guessing every detail.
Shipping without external validation is hard — but also what makes it meaningful.
I'm glad the message resonated. I'd love to hear more about what you're building too!

That's so cool!
Just starting my first project as well, and wondering what your budget was on this project. How much did you have to spend to get this working? And what would your tips be to keep costs low?-
1
Thanks! I actually built it with $0 spent on ads or a team, just my own time and effort.
Here’s how I kept costs low:
Used free tiers from tools like Supabase
Designed and coded everything myself
Focused on solving the core problem first
My advice: launch with the basics, validate the idea, and improve as you go. The value matters more than the polish at the start.

Congrats! What tips do you have for launching on product hunt? (there are tons of people who've asked this question, but the answer is different every time!)
Especially from a top 5'er! Wicked.-
2
Thanks a lot! Honestly, the biggest thing for me was just launching, even with zero audience or prep.
A few tips that helped:
Make the landing clear & emotionally relatable
Be transparent and personal in your post
Engage in communities where you already hang out (like here!)
And remember: top 5 or not, if it resonates with one person, it’s worth it.

About
I created Controol because I was tired of feeling guilty every time I spent money — even when I had enough. Most budgeting apps focus on tracking the past, showing charts and spending categories that often make you feel

























5 Comments
Hey Maxi — first off, props for putting something new out there and being open to feedback. That alone puts you ahead of 90% of indie makers.
Now, I’ll shoot straight with you: your weekly recap idea is solid, especially the way you’re using AI to surface gentle, actionable nudges instead of just spitting out a data dump. The tip you shared (“Your biggest expense was dining out...”) is exactly the kind of low-friction guidance that resonates. If you lean into that tone, you’ve got something useful and human.
But—and it’s a big one—your homepage and overall positioning are hurting you. Badly.
I had a bit of extra space in a panel we rand this afternoon, so I picked some random IH sites that had recently posted to fill it (I was paying the panelists so might as well help someone out). We ran your site through a Capture60 panel process (diverse backgrounds, real users), and while many liked the concept, nearly all walked away confused. Like really confused... like you have a big problem on your hands confused (sorry this is real feedback from a real 20 person panel). A few critical things kept coming up:
🚫 The Name "Controol"
Let’s deal with this first because it’s killing your first impression.
Everyone either misread it as “Control,” or assumed the misspelling was a typo or placeholder. Only three users even could repearth the name. Your product name is not sticky — it’s slippery. The double-O might have been intended to be playful or memorable, but in practice, it's just invisible (or worse: confusing). It looks like a typo and reads like an error. Some thought it was two different products. If you have to explain the name every time, it’s not working for you.
Do this: Either commit to the spelling and explain the why clearly (brand story, mnemonic, etc.) or revert to something intuitive.
Not this: Leaving users confused before they even get to what you do.
🎯 What Are You Actually Selling?
Your current hero says:
Nice sentiment. But that’s a tagline, not a value prop. Most users had no idea what your product is or how it works from that first screen. Many thought it was just a “cute savings visualizer” or “money mood app.”
Do this: Lead with what Controol actually does. For example:
That’s tangible. Then follow it with your emotional hook: “Spend without guilt.”
Not this: “Log income, it’s distributed into boxes, percentages, something something guilt.” No one could summarize that back to us.
🤖 AI + Automation — You’re Hiding the Coolest Stuff
Only 2 out of 10 users noticed that Controol uses AI at all. That’s wild. You’re clearly building automation, possibly intelligent recommendations — but they’re buried under copy that sounds manual and vague.
Do this: Surface your automation. Say it plainly:
And in the recap email:
Not this: “Automatically distributed into boxes.” That sounds like a cereal promotion.
🛡️ Trust Signals Are MIA
A lot of people mentioned this — especially folks over 30. There’s no info on privacy, data security, or even pricing tiers. It feels too casual for a product touching your money.
Do this: Add a footer or section: “How we protect your data” / “Your info, encrypted.” Bonus if you can show a human face or founder story. Right now it looks like a no-name template with vibes but no backbone.
Not this: Relying on emojis and a soft tone to imply trust. That’s not how wallets work.
📉 Bottom Line
You’ve built a tool for emotional finance clarity. But your site markets it like an aesthetic toy and hides the actual mechanics. In general my feedback is: Vibe-heavy, substance-light copy -> Clarity, clarity, clarity. Lead with what it does
This must have been written by an LLM!
The answer is... some of it, lol. It's a mix of the raw output from our reporting platform (structured by an LLM, but human-driven) and my own writing (which definitely carries its own style fingerprints of years spent in marketing).
A little context on our product might help:
Capture60 is a user research platform built to democratize user research and make it affordable for the average start-up. Most people don’t realize how stupidly expensive user research is — the big players are literally paying thousands of dollars for it.
What We Do: Real feedback, real fast. We help you explain your product better and get more people to care.
🙋♀️ Real People, Real Reactions: We put your product in front of actual humans and ask: Do they get it? Are they confused? Do they care?
🤖 Smart Layer of AI: We blend human insights with AI to show you what's working, what's not, and what you should fix first.
📈 One Clear Report – $30.
Why? Because we focus on one crucial question: "Do people understand what you're selling?"
(Users misunderstanding your value prop is the #1 reason they bounce. Fixing that first 60 seconds is the highest ROI move you can make. Honestly, it's the mistake I see the most when browsing sites.)
So, the long and not so short explanation:
We run panels with real people.
We run that data through an LLM, adding our own "special sauce" to make the insights more predictive across a wider audience.
Our team then reviews and refines the output to make sure it actually matches the data (because, let’s be honest, LLMs will sometimes just make things up). In this case, I was the one who ran the panel and did the touch-up.
We turn that context into a structured report, making it easy for the client to digest inside our platform.
Then, for the post above, I grabbed the most useful bits from that report, tweaked them to work as a post, and here we are. The end result... Probably 50/50 me vs Capture60 reporting. If you want to learn more about our reporting you can find the details at: https://capture60.com/blog/decoding-the-capture60-insights-report
If you want to confirm I am human you can ask me how many r's are in strawberry.
Really like how you’re turning raw numbers into a rhythm, the kind of check-in that actually helps people notice trends without drowning them in dashboards. The AI-generated tips are a nice touch too: actionable without being overbearing. Personally, I’d lean weekly, it keeps the feedback loop tight and makes adjustments feel more doable.
We’re launching something in a totally different lane (AI chess coaching), but this kind of “gentle insight, zero friction” philosophy is something we’re trying to channel too.
Curious to see how your users respond.
Thanks so much — I really appreciate your words! 🙌
That “rhythm without dashboards” insight is spot on. I’ve always felt people need clarity, not complexity.
Love what you're building too — AI chess coaching sounds amazing, and I’m totally aligned with the “gentle insight, zero friction” approach.
Let’s keep in touch — would love to hear how your launch goes too!
