### 3/5 — Meh

*2026-09-09*

Was working great but then stopped and it won’t let me purchase the pro version.

**Developer response:** Thank you for the feedback, and we are sorry for the trouble. We found the cause: the Pro upgrade was mistakenly available only in some regions, so it could not load for you. This is now fixed on our side, and no app update is needed. Please try upgrading to Pro again from the app. Your readings are safe, and recording always stays free. An update with further improvements, including new trigger and reliever insights for Pro, is also on the way.
