Know how much you know.
A private prediction journal. Write down what you expect, say how sure you are, resolve it later, and watch how well your confidence matches reality.
What it is
- Predict. A sentence, a confidence from 50 to 99%, a resolve date and an optional tag. Nothing is ever certain, so there is no 100%.
- Locked after an hour. Once the edit window closes, a prediction can't be reworded. That protects you from hindsight.
- Resolve. Only you mark an outcome Yes, No or Unclear. Unclear is kept but never scored.
- Humble statistics. A calibration bin appears only with enough resolved predictions, and sample sizes are always shown. “At 80% you were right 11 of 17 times.”
- Your confidence is yours. Nothing in the app, including its optional on-device writing help, suggests or pre-fills a confidence value or an outcome.
- iPhone and Android. Both apps share one data model and one export format, so you can move between them.

In developmentCore features are planned to stay free: predicting, resolving, the calibration view, tags, widgets, notifications and export. You will never be charged for access to your own data.

Questions
Is there an account or a server?
No. Your predictions live on your device and in your own iCloud or Google backup.
Is there AI in it?
Optionally, and only on your device. It can help make a prediction checkable or understand a sentence you dictated. It never touches your confidence or your outcomes, and it is off until you switch it on.
Will it nag or reward me?
No. There are no streaks, badges, points or confetti. The only notification is that a prediction is due to resolve, and a Monday prompt you can opt into.
Privacy
