Launched my first solo app after months of building — a focus timer for people tired of bloated productivity apps

Just shipped Viovi Focus on iOS and Android after a few months of solo development. It's a focus timer built around one idea: every existing focus app I tried felt bloated — gamification I didn't want, settings I never touched, or a paywall before I could even try it.

What it does:

- One tap to start a session, no setup

- Live Activity on the lock screen so you can see your session without opening the app

- Daily history to see how much focused time you actually logged

- No streaks, no badges, no guilt-tripping notifications

Stack: React Native/Expo, Supabase, RevenueCat for subscriptions.

The App Store/Play Store review process alone was its own adventure — happy to share details if anyone's going through that right now.

7-day free trial, then subscription-based.

Would appreciate any feedback, especially from anyone who's tried similar apps and bounced off them for the same reasons I did.

    The failure-first positioning is clear. Have beta users actually replaced hand-rolled failure tests or existing mock tools with MockBase, or do they mostly agree the problem exists without changing their workflow?

      Thanks for the comment! I think this might be meant for a different post — Viovi Focus is a focus timer app, not related to mock APIs or failure testing. Happy to answer questions about Viovi Focus if you have any!

        The no-bloat positioning is clear. Have early users actually stuck with Viovi Focus longer than they did with the bloated alternatives, or is retention still the main thing you’re testing?

          Honest answer: retention is still the main thing I'm testing. The app just launched, so I don't have enough data yet to say people are sticking with it longer than bloated alternatives — that's the real test ahead. What I can say is the early feedback (mostly from friends/beta testers before launch) was that the simplicity itself was the appeal — people who'd abandoned other focus apps after a week said this felt lighter to just... use. But "felt lighter in week one" and "still using it in month two" are very different claims, and I only have data for the first one right now. I'm planning to track daily/weekly active sessions closely over the next few months to see if that initial reaction holds up.
