Mistake Board is a local-first reflection tool for everyday mistakes.
Use it to record small misses in work, communication, spending, emotions, and daily life. The goal is not to blame yourself. The goal is to turn one mistake into a reminder you can actually use next time.
You can:
- Pin a mistake as a note
- Write what happened, why it happened, and how to avoid it
- Keep active notes on a reflection board
- File resolved notes into your record library
- Review weekly patterns and prevention cards
The current version does not require an account. Your records stay on your device. Nothing is uploaded to a server.
Optional one-time Pro unlocks a privacy lock, extra reminders, and Home Screen / Lock Screen widgets for your current rule. Recording, the board, review, export, and backup stay free.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
When something happens again, log it on the original record with “It Happened Again.” A filed note returns to the board. Record details now include an occurrence summary and timeline, with undo for the latest recurrence. Filter and sort recurring records, and see recurrences and affected records in your 7-day or 30-day review.
Backups now include the full event history. Preview differences before restoring; merge keeps the local version of conflicting records. Export a current backup before replacing your data. History that older versions never saved is not reconstructed.
All these features are free. The existing Pro one-time purchase remains unchanged.
