One star is generous, you can't give zero. The main problem is that you cannot set the breathing pace, and their device uses a proprietary interface that won't connect with the many useful HRV apps that do let you set your breathing pace. Further, there are no statistics. It doesn't give a hint of your HRV over the course of a session, nor does it store any scores from previous sessions. Apparently, progress in unimportant. It galling that it doesn't give useful statistics. They clearly spent a lot of time on the nice music, and the fancy pictures (pretty, but without any purpose). Overall the if they added an option to allow the user to set the breath pace, kept the music, and added a simple graphic to show your breath pace and where you are in the cycle, it could become useful, as the device itself seems well made.

I just installed the app on my old Samsung Galaxy A10e and tried it out. It works perfectly. The visuals are beautiful, and the music, sounds of nature, and the soothing vocals are super calming and relaxing. Now, I need to buy an external speaker so that I can put it by my bedside to help me fall asleep. Thank you for this wonderful device.

Will not pair (Bluetooth) with OX200 even though it seems it. No pairing, no connection, no data.... I agree with others, app asked for way more permissions than necessary. Removing from my phone and will not bother to try a later version. Not worth it. [edit] After being told to try again, it still does not pair. (Yes, it is on my finger). Even if it did work, the permissions required by the app are excessive. Deleting app. Using device standalone.

Hi! The device needs to be on the finger when registering the unit. The BLE device sends the necessary code to the app during registration. If the device is not on, no connection can be made. I hope this information helps!
