Stop overthinking, anxiety and worry - with CBT and ACT tools built for real life.
Formerly Luma: same app, same account. It may still show the Luma name and icon on your phone until our next update.
Your brain won't switch off. You keep circling the same worry, picking apart every outcome, every possibility, every mistake. You know it's not helping. But you can't seem to stop.
WorryTree was built for exactly this. It's a pocket toolkit for anxious thoughts, intrusive thoughts and panic - built on CBT (Cognitive Behavioral Therapy) and ACT (Acceptance & Commitment Therapy), two widely used, evidence-based approaches to managing stress, overthinking and emotional overwhelm.
Named best CBT app by Marie Claire. As featured in The Guardian and Well+Good. Named “Hot Right Now” on the Apple App Store.

👤 Built Around a Technique Therapists Teach
The worry tree is a CBT exercise many therapists use: write the worry down, ask whether you can do anything about it, then make a small plan or let it go for now. WorryTree started in 2019 to make that exercise easy to use day to day — not just on your worst days, but on ordinary ones too, before things spiral. It's for people who want structure and evidence, not apps that tell you to breathe and hope for the best.
