I Built an App to Train Optimism. I Didn’t Expect Anyone Else to Want It

Like many side projects, this one started with a problem I was trying to solve for myself.

I noticed how easy it was to fall into negative thinking. A small setback could ruin my mood for hours, and simply telling myself to “think positive” never worked.

So I asked myself a different question:

What if optimism was something you could practice, just like any other habit?

That idea turned into an iOS app.

Before opening selected apps, it asks you to reframe one negative thought into something more balanced or constructive. The goal isn’t forced positivity. It’s creating a small pause that helps break automatic negative thinking.

I built it expecting to use it myself.

I almost didn’t publish it because I assumed it was too niche.

Five days after launching on the App Store, it had reached 732 downloads.

That was a good reminder of something I keep forgetting as an indie developer:

The problems that feel “too personal” are often shared by more people than you think.

As developers, we sometimes spend weeks searching for the next big idea, when the best products are hiding in our own daily frustrations.

This project reinforced a simple lesson for me:

Build something you’d genuinely use. Then let the market decide whether other people need it too.

I’d also love to hear from other indie developers. Have your most successful projects started as tools you built for yourself?
