Frequently Asked Questions

We collected common questions about installation, data storage, and safety. Check these key points before adding Flowtime to your home screen.

No. You can start using Flowtime directly in your browser without installing anything. Just open the site and start the timer like any other web page. Once you find yourself using it every day, we recommend adding it to your home screen as a PWA. This gives you an app-like icon and one-tap launch, similar to a native app. In other words: installation is not required to try it, and adding it to the home screen becomes useful once Flowtime is part of your daily routine.
