Tempo

Minimal billable hours tracker for Android. One tap to start

August 31, 2026 I built an Android app as a non-developer Technical PM β€” no code, just AI tools

Hey IH! πŸ‘‹

I'm a Technical PM and over the last 2-3 months I built and shipped my first Android app solo. No coding background, just AI tools and a problem I wanted to solve.

The problem: I kept losing billable hours between clients. Every time tracker I tried (Toggl, Clockify, Harvest) was either too complex or too ugly to open every day. I wanted one tap to start, one tap to stop β€” nothing else.

So I built Tempo.

- One tap to start/stop tracking

- Billable vs non-billable toggle per session

- Daily & weekly reports

- Custom projects with icons & colors

- Fully offline β€” no account needed

What I learned shipping solo:

1. Simplicity is harder than complexity β€” deciding what NOT to build was the real work

2. Early testers catch everything β€” bugs, UX issues, missing features

3. The story matters as much as the product β€” people connect with the why

Just hit 10 downloads on day one with zero marketing. Now figuring out distribution.

Would love your feedback:

- What channels have worked for you to get first 100 downloads?

- Any advice for a first-time solo founder?

    Echo to your point 3 that "people connect with the why": I have seen my alternative ran earlier and faster simply by telling a stronger story around his product, and that’s definitely something I’m trying to learn from. For my own growth story: I got my first 700+ sign-ups by launching on Product Hunt, plus featured in 2 newsletters right after the launch. Out of those, 200+ were friends and friends of friends, so about 500 strangers ended up trying my product. I did get some paying users and learned which part I need to iterate on next by reading my funnels. Even so, I still struggle with selling my product. IWould love to hear stories from you and other fellow founders here.
