Over time, thnk begins to understand you better and can help identify patterns. For the sake of privacy, all of your data will only be stored locally on your device.

Especially adults with ADHD - or anyone who finds it hard to simply start. WHAT IS PUFF Puff is a cozy focus companion and cognitive training app designed for ADHD-friendly productivity.
