Pomodoro Study Timer & Tracker
Read full descriptionHide full description
A calmer take on the pomodoro technique: real blocks, real breaks โ and the next block is always your choice. Calibrate is built for the moment before you begin. The task is big, the hour is open, and starting is the hard part. START FROM YOUR LIST Swipe any to-do and you start with three easy minutes. Then your block carries on by itself. REAL BLOCKS, REAL BREAKS Each block ends with one question: how was your focus? Answer, and your break begins. Come back when you're ready. YOUR LOCK SCREEN DOES THE WORK The whole session lives on your Lock Screen and Apple Watch โ the countdown, the check-ins, the next-block choice. Nothing needs unlocking. You never have to open the app. EMPTY YOUR HEAD FIRST Brain-dump every loose thing into one list for today. Spaces keep work, home and health apart, so today stays short. Every to-do gets a day โ or waits, without nagging you. AN HONEST WEEK, NOT A SCORE The weekly recap shows what actually happened โ facts, never grades. No streaks, no scores. Miss a day, nothing breaks. WHO IT'S FOR Students in long study sessions. ADHD brains โ the app never punishes a wandered mind, it just asks kindly. Anyone who's tried blockers and streak apps and wants something gentler. Calibrate helps you notice. It never notices for you. Focus sessions, to-dos, spaces, lists and keeping track are free โ all of it, unlimited. Calibrate Plus adds the long view: your weekly recap, your sharpest hours, and every day you turned up. Monthly, or one purchase that's yours for good. Privacy policy: https://usecalibrate.app/privacy.html Terms of use: https://usecalibrate.app/terms.html

Reefie turns focused work into a dive. Choose a depth - anywhere from 10 to 120 metres. A metre is a minute, so 45 m is a 45-minute session. Drop the line, do your work, and if you stay under until the timer ends, whatever was circling down there follows you home. SIXTY SPECIES, BY DEPTH Common fish drift through the shallows. Rarer things live further down, and the legendaries only stir below 85 metres. Every catch fills a page in your Ocean Book, so a long dive is worth more than two short ones - in pearls, and in what you can actually find. DEEP FOCUS Switch it on and leaving the app ends the dive. The line snaps and the catch is lost. Reefie cannot block other apps and doesn't pretend to - it just makes walking away cost something, which for most people is enough. DIVE TOGETHER Add friends by diver name to see their reef. Trade the species you have doubles of. Join a room to work towards a shared total, or race a weekly leaderboard that resets every Monday. YOUR REEF Pearls from every dive buy boats and hooks, and one-dive boosts when you want better odds on a deep run. YOUR REEF FOLLOWS YOU Sign up with an email address, or use Sign in with Apple. Your collection lives on your account, not on one phone - change handset or reinstall and it is still there. There are no ads, no third-party trackers, and nothing is sold to anyone. You can delete your account and everything in it with one button in Settings. REEFIE PRO (optional) A subscription for divers who want better odds: +10% catch chance on every dive, boosted rare and legendary weighting, and +25% pearls from every catch. Monthly, yearly, or a one-time lifetime purchase. Reefie works completely without it. Reefie Pro Monthly and Reefie Pro Yearly are auto-renewing subscriptions. Payment is charged to your Apple ID at confirmation of purchase, and renews at the same price unless cancelled at least 24 hours before the end of the current period; your Apple ID is charged for renewal within 24 hours before the period ends. Manage or cancel any time in your Apple ID settings. Reefie Pro Lifetime is a one-time purchase and never renews.
