Flow Clock is a minimal yet potent tool designed to make the Pomodoro technique and time management effortless. 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 ### Key Features - Flexible Pomodoro timer to suit your workflow - Block distracting apps and stay focused - Tag and comment on your focus sessions - Visual timeline to review your day at a glance - Insightful stats on how you spend your time - Break and relaxation timer ### Adaptive Pomodoro The Pomodoro technique has been proven to improve productivity and reduce procrastination. The core idea of this technique is to intersperse focused work with short breaks, giving your brain time to refresh and maximizing the benefits of both focused and diffused thinking. However, no evidence supports that the famous 25-minute work and 5-minute break pattern is a one-size-fits-all best practice. In fact, different people have different tendencies, and different tasks require different strategies. Flow Clock encourages you to adapt the Pomodoro technique to your specific needs, freeing you from rigid protocols and complex tools. You can set each focus session to anywhere between 10–60 minutes, or even forget about the time limit, tailoring it to the specific task and your unique work pattern. The neat and minimal design aims not only for aesthetics but also for an easy and efficient experience. ### Flow Clock PRO Flow Clock is free to use forever. To access additional features like unlimited focus tags and more, you can upgrade to Flow Clock PRO within the app. Subscriptions will automatically renew unless canceled at least 24 hours before the end of the current period via your iTunes account. ### Terms & Support Terms of Use: https://rian-qu.notion.site/tomatoclock-terms-of-use-en Privacy Policy: https://rian-qu.notion.site/tomatoclock-privacy-policy-en If you have any questions or issues, please email us at tomatoclock25@gmail.com.
