Den Krøllede Hjerne

Den Krøllede Hjerne is a small, comfy app for your mental well-being.

Built around proven CBT- and MBT-techniques — without the clinical staging. A great supplement if you're already in therapy, and works fine on its own too.

— Worry Box —
Lock a worry away. Pick a time it's allowed back out. When the box opens, you decide whether the worry still matters or can be released. Most people find that far fewer worries survive a night's sleep than they thought.

— 13 CBT tools —
Challenge negative thoughts, practice kind self-talk, break avoidance patterns, test your beliefs in everyday life. Each tool walks you through the steps without pushing — you can always stop, save, and come back.

— Breathing + reflection —
Box breathing, 4-7-8, and diaphragmatic breathing for when the body moves faster than the mind. Plus journaling, gratitude, and dream logs for the quieter moments.

— Daily check-ins —
A short check on mood, sleep, and energy. Builds a thread over time so you can see patterns — without the app pressuring you to maintain a streak at any cost.

— Habits + plans —
Follow through on small habits, plan experiments with yourself, review what worked.

No ads. No pop-ups trying to sell upgrades. No sharing with third parties beyond what's needed for the app to work.

Your thoughts stay with you.
