### 5/5 — Helpful meditation app

*2026-05-27*

Very clear and easy to use. One question is that: I do not have the HRV analysis yet. Do I need to meditate for hours before I can see the analysis or how can I see the HRV analysis on my app.

### 4/5 — No notification after one round ends

*2026-04-20*

Like the style and function, but when then round ends, there’s no notification ring, the user don’t know it’s already finished. Hope this could be solved

**Developer response:** Hi, thanks so much for the kind words and for reporting this! You were absolutely right — in our previous release, the end-of-session notification didn't reliably fire when the app was in the background or the screen was locked. We've just released v3.3.3 which fixes exactly this: a proper local notification now alerts you when your meditation round ends, even with your phone locked. Please update to v3.3.3 from the App Store and give it a try. Thanks again for helping us improve the app!
