Overthinking? Worry on a loop? WorryTree helps you write the worry down, check whether you can do anything about it, and then act on it or let it go. Formerly Luma: same app, same account, same tools. Named best CBT app by Marie Claire (2023). HOW IT WORKS • Write it down: get the worry out of your head and into words. • Run it through the worry tree: can you do something about this? • Yes: make a short plan and choose one step to start with. • No: let it go for now, with a walk, some music or a short sensory practice. • Look back: see which worries actually happened, and what helped before. ALSO IN WORRYTREE • Notice thinking traps: check a thought against 8 common thinking styles • Gratitude, acceptance and uncertainty journals • Short sensory practices for in-the-moment calm • Worry time reminders • Works across your devices BUILT ON CBT AND ACT The worry tree is a widely used technique from cognitive behavioral therapy (CBT). WorryTree also draws on acceptance and commitment therapy (ACT). Many people use it alongside therapy, and many reviewers say a therapist or CBT course recommended it.
