Billd — free Android app that shows freelancers their earned vs missed income daily
Built this for myself because I needed it.
Billd is a free Android app for freelancers. You enter your hourly rate once, log your hours each day, and it tells you exactly what you earned — and what you left on the table by not working.
No accounts. No cloud sync. No subscription. Everything stays on device.
I built it in Flutter with zero Flutter experience. Shipped it. It runs on Android 15. The whole app is a single file. I'm not proud of that last part, but it works.
In Google Play closed testing now. Need 12 people to use it for 14 days so I can unlock production publishing.
If you freelance and you're on Android: https://forms.gle/5KeUW3XF5HYeHxq7A
Takes 20 seconds to fill out. I'll add you to the beta track the same day.
Nice Android-first positioning. One thing I learned launching Kinetic Override is that utility apps need to show the trust model before the feature list: where data lives, why permissions exist, and what the first successful action looks like. For your app that might be the “earned vs missed income” moment in the first screenshot/onboarding step.
