For people who outgrew pomodoro: empty your head, sit with one thing, and let your Lock Screen check in. No streaks, no shame.
Calibrate is a deep focus timer with a simple idea: empty your head first, then sit with one thing.
Start with a brain dump — 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
• Deep focus sessions — open-ended, with gentle check-ins at your rhythm
• Live Activity on the Lock Screen — your sitting stays present without unlocking your phone
• Brain dump to to-dos — capture fast, sort into spaces later
• The done list — finished things stay visible; your day ends with evidence, not guilt
• Keeping track — "when did I last change the filter?" Cross a to-do off, keep track of it, and the date is always there
• Weekly recap — your week, mirrored back in one calm card, with one line you carry into the next
• No streaks, no shame, no red badges — 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 — ADHD brains welcome; the app never punishes a wandered mind, it just asks kindly.
Free for 14 days, everything open — 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).

A better beginning: Calibrate now asks what brings you here, and starts with the door that fits.
Plus small fixes and calmer edges throughout.
