User Reviews

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.

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
