Prices are shown in US dollars and are set in Google Play; you are charged in your own local currency, and Google Play shows you the exact amount before you confirm. There is no free trial — you buy directly, so you are never charged at the end of a trial you forgot about. All purchases are processed by Google Play; we never see or store your card details.
Full refund & cancellation policy, and the terms of use.

Focus, reclaimed
A digital-wellbeing app that quietly walls off distracting apps and screen time, so your attention comes back to you.
In development03 — Refusals
What we refuse to do is as important as what we build.
01
On your device, always.
Every app does its data work locally — your logs, habits, and history never leave your phone.
02
No tracking, no analytics on you.
We don't need to watch you to build something good.
03
No dark patterns.
No fake urgency, no guilt streaks, no traps to cancel. Leaving is as easy as arriving.
04
You own your data.
Export it, delete it, take it with you — it was always yours.
05
Built by hand, one at a time.
Each app ships only when it earns a place on your home screen.
