Flow Clock is a minimal, flexible tool designed to make the Pomodoro technique and time management simple. Alongside your time records, you can keep notes, photos and a diary, so reviewing your day means more than looking at a set of numbers. You can use Flow Clock when you... ... need to concentrate ... wonder where your time went every day ... want to reduce procrastination ... are studying for an exam ... work from home ... want to record your day and understand your own rhythm ## Key Features - Flexible Pomodoro timer: choose a focus theme and duration, or leave the timer open-ended; start, pause and resume at your own pace - Focus and relaxation: make room for breaks, with ambient sounds to suit the moment - Block distracting apps: keep only your chosen apps available during focus sessions - Time records: add notes, time tags and photos, or add and adjust records later - Visual timeline: review your focus and relaxation sessions by day or week - Diary: bring together writing, photos, places and weather to remember more of your day - Stats and charts: explore how you spend your time through focus themes, time tags and trends - Widgets and Live Activities: start a timer and keep its progress close at hand - Sync to Calendar: add your time records to a system calendar of your choice - iCloud sync: continue your current timer and access records and diary entries across iPhone, iPad and Mac, using the same Apple Account with iCloud enabled Some features require PRO. You can review the available benefits in the app. ## Adaptive Pomodoro The core idea of the Pomodoro technique is to alternate focused work with short breaks, giving yourself time to recharge. But 25 minutes of work and 5 minutes of rest may not be the best fit for every person or every task. Flow Clock encourages you to adapt the technique to your needs, freeing you from rigid routines and complex tools. Choose a duration or leave the end time open. Organize work, study, reading or exercise with focus themes, then use your timeline, diary and stats to reflect on what worked and what you might change. The neat and minimal design aims not only for aesthetics but also for an easy and efficient experience. ## Flow Clock PRO Flow Clock's core features are free to use. PRO unlocks unlimited focus themes, longer and open-ended timers, the full set of stats and ambient sounds, plus diary writing, time tags, app blocking, calendar sync and widgets. Choose a monthly subscription, yearly subscription or one-time purchase. See the app for current prices and benefits. Monthly and yearly subscriptions renew automatically unless canceled before renewal; manage or cancel them in your Apple Account's subscription settings. One-time purchases do not renew. ## Terms & Support Terms of Use: https://wildhut.tech/flow-clock/en/terms/ Privacy Policy: https://wildhut.tech/flow-clock/en/privacy/ If you have any questions or suggestions, please email us at tomatoclock25@gmail.com.
