I build calm Android apps that respect you.

No ads. No tracking. No dark patterns. Just calm, simple apps that do one thing well — and respect your time, money, and privacy.

One thing well

Each app has a single clear job and does it without clutter or feature bloat.

Your data stays yours

Offline-first by default. No accounts, no harvesting, nothing sold to anyone.

No dark patterns

No nags, no fake urgency, no traps. Free means free — not free-until-you're-hooked.
