ThunDroid AI

Clinical-grade CBT, DBT & ACT - no appointment, no waitlist. Stanford-backed Cyclic Sighing, 13 breathing techniques, AI voice mode & encrypted journal. 3-day free trial.

The only AI companion trained on CBT, DBT, and ACT therapy frameworks not a mood app. A helpful tool that works when therapy is unavailable.

CBT · DBT · ACT - ALL THREE FRAMEWORKS IN ONE APP Most apps pick one. ThunDroid includes all three evidence-based therapy approaches used by licensed therapists worldwide. Whether you need CBT thought records to challenge anxious thinking, DBT diary card tracking to regulate intense emotions, or ACT-based defusion techniques to stop avoiding what hurts it's all here, guided by AI that adapts to your pattern over time.

CYCLIC SIGHING - STANFORD-VALIDATED IN 5 MINUTES The fastest science-backed stress reset that exists. A Stanford study showed cyclic sighing reduces anxiety faster than mindfulness meditation. ThunDroid guides you through it with real-time visual and haptic feedback. Works fully offline. Used by people who don't have 30 minutes to meditate.
