Building a minimalist goal tracker that rewards top users with cash & visibility

Hey 👋

I’m working on a simple productivity tool that tracks your daily goals — but with a twist. Instead of just helping people stay on track, I wanted to make things fun, rewarding, and maybe a little competitive.

The idea:
Users set 3 goals every day

The app tracks how quickly and genuinely those goals get completed

An ML-based scoring algorithm ranks everyone monthly

The top 3 users win $30 / $20 / $10

The top 20 get featured on an achievement board

Users who build or finish something noteworthy also get a chance to be showcased on the homepage

All of this is being built with zero fluff — no dashboards full of widgets or overly complex productivity systems. The design goal is to keep it dead simple and focused on effort, consistency, and impact.

Why I’m building it:
I've always found productivity apps overwhelming. Most of them feel more like a place to procrastinate. But when I set only 3 clear goals per day and had a reason to complete them (even small rewards or recognition), I was way more productive — like 10x more. The psychology of limitation + competition really works.

A few notes:
It’s inspired by 3goals.today, but I'm building in more automation, fairness, and community elements

It's going to be open-source

I'm not trying to build a classic SaaS — no $20/mo pricing. I just want to cover basic server costs and prize pool, so I’m asking for $1/mo support from users

I can personally fund rewards for the first ~3 months, but beyond that I’ll need the community’s help to keep it running sustainably

Demo:

What I’m looking for:
Feedback on how minimal the UI should stay (I’m tempted to keep it super lean, but curious what others think)

Suggestions on anti-cheat mechanisms that aren’t too intrusive

Someone with math/ML experience to help refine the scoring algorithm a bit

Anyone who’s tried similar ideas or launched productivity tools — I’d love to learn from your experience

Let me know what you think! Would this kind of system keep you motivated? What would make it more useful for you?
