About

Deep Focus Timer

Features
Read full description

Calibrate is a deep focus timer with a simple idea: empty your head first, then sit with one thing. Start with a brain dump β€” everything on your mind becomes a simple, organized to-do list. Swipe one line to begin a focus session. While you sit, Calibrate checks in quietly on your Lock Screen: still present, or did something pull you away? You answer in one tap. That's the whole mechanic. If you've outgrown the rigid 25/5 of pomodoro, this is what comes after: sessions that fit you, gentle check-ins instead of alarms, and an honest record instead of a score. Over time, the answers become something rare: an honest record of your attention. Not a score. Not a streak. A quiet mirror. WHAT'S INSIDE β€’ Deep focus sessions β€” open-ended, with gentle check-ins at your rhythm β€’ Live Activity on the Lock Screen β€” your sitting stays present without unlocking your phone β€’ Brain dump to to-dos β€” capture fast, sort into spaces later β€’ The done list β€” finished things stay visible; your day ends with evidence, not guilt β€’ Keeping track β€” "when did I last change the filter?" Cross a to-do off, keep track of it, and the date is always there β€’ Weekly recap β€” your week, mirrored back in one calm card, with one line you carry into the next β€’ No streaks, no shame, no red badges β€” Calibrate helps you notice; it never judges WHO IT'S FOR People who've tried blockers and streak apps and want something gentler. Students in long study sessions. Anyone whose attention wanders β€” ADHD brains welcome; the app never punishes a wandered mind, it just asks kindly. Free for 14 days, everything open β€” no card needed. After that, your to-dos, journal, and history stay free forever. Calibrate Plus (focus sessions, habit intelligence, new weekly recaps) is a monthly or yearly subscription (prices shown in the App Store).
