Deep Focus Timer
Read full descriptionHide 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 โ 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 โข Deep focus sessions โ open-ended, with gentle check-ins at your rhythm โข Live Activity on the Lock Screen โ your sitting stays present without unlocking your phone โข Brain dump to to-dos โ capture fast, sort into spaces later โข The done list โ finished things stay visible; your day ends with evidence, not guilt โข Keeping track โ "when did I last change the filter?" Cross a to-do off, keep track of it, and the date is always there โข Weekly recap โ your week, mirrored back in one calm card, with one line you carry into the next โข No streaks, no shame, no red badges โ 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 โ ADHD brains welcome; the app never punishes a wandered mind, it just asks kindly. Free for 14 days, everything open โ 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).

Clair App

Clair brings your tasks, quick notes, and ideas together in one clean, simple app. No clutter, no sign-in, no subscriptions, just three focused tabs that work the way you think. Todos: Capture tasks the way you'd send a message, type it, hit send, done. Set reminders so nothing slips through. Add priority flags to see what matters most at a glance. Sort your list the way that works for you. Cards: Quick sticky notes for anything you need to jot down fast, a thought, a reminder, a snippet to refer back to later. Choose from a range of colors to organize visually, and sort your cards however you like. Notes: A full notes experience when you need more space to think. Organize with folders, write in Markdown for clean formatting, and sort to find what you need quickly. Make it yours: Customize Clair with accent colors and font options so the app feels like your own. Privacy first: Clair works entirely on your device, with no accounts, no tracking, and no logins. Your data is yours. Clair is aimed at anyone juggling multiple lightweight capture tools, such as a todo list, a notes app, and a place for quick reminders, who wants them combined into one simple interface instead of switching between separate apps. It solves the friction of that context switching by keeping fast task capture, quick notes, and longer form writing in one clean, three tab app.

Verdict
The clearest difference is in-app purchases: Clair App at none against Deep Focus Timer's 3. Clair App also leads on update cadence (every 2 days vs every 5 days). On price, ads, device support and iOS requirement there is nothing between them.
