Looking for your feedback - Does my landing page come across as professional or amateurish?

It's a great start! If I understand it, you're looking to start a website to offer personal financial advice. It will help people maximize their future cash flow.

To make it look more 'professional' I would remove the image of cash and the dollar emoji. Replace it with images of people. If you focus on the money in images, it looks scammy. If you focus on people it looks like you are into helping people.

I think you should find a better phrase than 'My Cash Flow Plan'.

I don't think of my budget in terms of 'cash flow' because I tend to think of that when I think of businesses. I might understand it better if you said, 'personal future budgets'. Or something with that type of wording.

"I'm curious if an app dealing with money requires a very high level of trust before someone gets started with it even if there is no personal data required."

I think it would require a medium to a high level of trust. At a minimum, you'd want to be perceived as knowledgeable.

It would be more useful to provide an ability to import past data and predict future cash flow based on past information. It gives people motivation to change now because it gives them a tangible way to see the results of their current actions.

And it makes it super easy to fill out that future prediction of what their cash flow will be if it's based on past events. People love easy.

Here's a business that does personal finances advice and they sell it as personal trainers and charge a monthly fee. https://financialgym.com/

You can listen to their blog to learn more about the industry. Even though their product is different. You have enough similarities to be useful. In the podcast, they specifically talk about how it's difficult to get people to open up about their finances. And how cov-id impacts people's spending habits.

They also mention how they used the phrasing of gym membership on purpose because when you say 'gym' people are already trained to pay a monthly fee. Using 'budget' could also be useful because people are used to the idea of using money management software that charges a monthly fee.

Hey Mitch,
I only looked at the landing page. Here's' my 2c and first contribution to Indie Hackers. I think you need to be more specific about who you are targeting before you can assess whether the site is giving a good first impression or not. Craigslist looks terrible but that's part of its brand and ethos.
You say the app is for a 'general customer', who do you see as the general customer?
You've used USD notes as the wallpaper so I presume it's an American audience, terms like "your cash" so I assume it's an individual not a business (so your business model is B2C). Using terms like "cash" instead of "wealth" or "legacy" suggests it's an American millennial and I can see the Incomes of $1750, so they don't earn mega bucks but have some disposable income... and so on.
From that you can from an identity for yourself which speaks to that audience. I would recommend looking at competition sites who cater to the same imagined customer and asking yourself "is what I have ticking the boxes they do"? Because they probably spent good $ researching it.
You could look at https://onepagelove.com/ or companies like https://flinks.com/ and https://www.gini.co/ for example.
Yes, I would say for any financial products you need to give the impression of intelligence, stability, modernity, security to build trust. Financial information is private and sensitive.

Having a more technical look at the styles you have used on the site, the colours, the fonts, the diagrams, I would say they look quite basic, like something you might see in MS Office. I think the logo needs to include the concepts of cash and planning, like a calendar with a dollar, the concept isn't there currently. Obvious as it sounds the identity is conveyed by these technical details and forms how customers understand your product. Having a well thought out custom design gives an impression of quality.

To get ahead quicker with UI development you could just look at a company targeting a similar market, buy a HTML template with all the components you need and copy your content across. A bootstrap HTML template is easy to get started with eg https://themeforest.net/item/signflow-ultra-modern-tech-template/21297671

As for stating that it's not connected to your bank, you could explicitly say that in a Section with a graphic like a padlock.

Hey Mitch,
Forgive me if I am repeating some of the advice in the other comments, but the things that stand out to me as being untrustworthy or amateur are:

• Cash header image
• Dollar logo
• Font choices
• Colors

What I would do to make this site feel a bit more legit would be:

• Swap the cash photo with something like a really cool gradient background (https://cssgradient.io/gradient-backgrounds/), make the header text bigger and left-aligned (let it be the main focus), and maybe put some subtle graphic on the right side. Look at https://fuselabcreative.com as an example.

• I think you can go to Fiverr and get a better logo for pretty cheap. Even like $40 can get you a good logo (https://www.fiverr.com/milanmanojlovic/do-a-flat-logo-design-3060449e-f727-48d3-ab00-7a289cb62792?context_referrer=search_gigs_with_modalities_logo_maker_banner&source=main_banner&ref_ctx_id=8e7c51a5cb699137c8199fb84afcf4f2&pckg_id=1&pos=11&context_type=auto&funnel=8e7c51a5cb699137c8199fb84afcf4f2&imp_id=760f4aa2-c7a2-4d05-964b-507c7ca4f950)

• For fonts, get one display font (headers) and one copy font (body copy, subheads, etc.). I'd go sans-serif because it's easier to read on a screen. I recommend Bebas Neue for the header (https://fonts.google.com/specimen/Bebas+Neue?category=Display) and Titillium Web for the copy font (https://fonts.google.com/specimen/Titillium+Web?category=Sans+Serif)

• Use https://coolors.co/442b48-726e60-98b06f-b6dc76-dbff76 to find a color palette you like. Just click the space bar to get random color combinations. You can lock a color you like in place and randomly generate the rest to see what matches. Honestly, it would probably be best to use white as the background color (or a super super light grey, like #f4f4f4), some kind of brand color (I can see #2FC479 working for you), and then an accent color that you would use sparingly (#F76161 is a reddish color that could work for buttons with a negative connotation, like delete, remove, etc.)
  Really, you should use white/your white equivalent (that really light grey), black text (white text if it's on top of the green) and that green color as any color callouts.

Outside of the UI tweaks, organizing the content to tell a story as the user goes down the page will just help them understand what's happening. and maybe include some social proof. Especially with handling money, I want to make sure it's legit, ya know?

Hope this is helpful!

Best,
Scotty

Hi Mitch! The layout is fine but the Typography and some of the colour choices could do with some work. Don’t worry though, I was woeful at this but did a course on UI and it helped a lot. I did mine through learnui with Erik Kennedy. It wasn’t cheap, around $1,000 from memory but there’s a bunch of good stuff on Udemy that you can do for a lot less. If you’re going to do your own design for your indie hacking, I can’t recommend this as a skill enough. It will set you apart.
