ThunDroid AI is your personal intelligence. It is an AI companion for feelings and ordinary days: talk when you need someone, write when you need to see a pattern, and breathe when your body is ahead of you. TALK Speak in Live Voice, or type. ThunDroid draws on CBT, DBT, and ACT, three approaches used in therapy, and stays with what you have already said. It is a companion for the moments between sessions. It does not replace a clinician. JOURNAL Fifteen guided templates, including a CBT thought record, a DBT diary card, gratitude, sleep, and goals, plus mood, streaks, and history. Journal entries are encrypted on your device with AES-256-GCM. BREATHE Thirteen guided techniques, including cyclic sighing, the exercise a Stanford study found reduced anxiety faster than mindfulness meditation, plus box breathing, 4-7-8, resonance, alternate nostril, and the Wim Hof method. Visual guides and haptic cues. Breathing works offline. PRIVACY Chat is sent over a secure connection to ThunDroid’s servers so the companion can respond. Your journal is different: it stays on your device, protected with AES-256-GCM. ThunDroid does not sell your journal or your conversations. Start with 3 days free. Full access. Cancel anytime.

Untwist

A difficult thought can feel like a knot. Untwist gives you a private, guided way to look at it from a little more distance — without a chatbot, an account, or pressure to keep a streak. CREATE A MIND KNOT Write the thought as it appears, notice its intensity, explore possible thinking patterns, and shape a more balanced perspective. Twisty changes with each step as you create more room around the thought. RETURN WHEN YOU NEED IT • Save unfinished reflections as drafts • Keep completed knots in your private Mind Journey • Search, edit, favorite, hide, or delete your entries • See gentle weekly insights about rhythm, intensity, and recurring patterns MORE SPACE, NOT MORE PRESSURE Use a quick mood check-in or a guided breathing space when a full reflection is not what you need. There are no streaks to protect and no guilt-based reminders. PRIVATE BY DESIGN Your thoughts, notes, and balanced perspectives stay on your device. Untwist does not send reflection content to analytics services. Subscription management is handled by RevenueCat without access to your journal content. IMPORTANT Untwist is a wellness and self-reflection tool. It does not provide therapy, diagnosis, treatment, or medical advice. Regional crisis resources remain available without a subscription.
