App is stuck in an infinite loop on my GS4 It connects easily to my BLE HRM (Zephyr HxM) and displays the bar graph no problem. However, when you stop recording, it asks for confirmation to stop and record the session..., and when given, it goes to the device search menu. From there, nothing is possible but to escape (quit) the app, or connect to the HRM again, and allegedly record a session. Does it record anything? SEE BELOW) Can it graph the data as shown in the poincoire (sp) plot on the icon: NO Can it analyze it's own data: NO Can it analyze any data: NO Does it perform the functions claimed: HELL NO Update: curiosity and hope made me explore more. I found the programming to be very German in style. By this I mean, like my German friends program: with little consideration for user operability or data transferability. For instance, they use db files, which are completely unnecessary, and are made using SQLite, meaning they used freeware to make it difficult for someone to copy, and therfore user unfriendly. Still hate it

Gave this app a poor review. Dev challenged me to name a better app. Sweetbeat HRV by a mile. Be careful what you wish for in future. You were lucky to get one star.

HRV is being used in many different ways and there are also many ways of analyzing the data. This simple, but powerful app, provides real time measurements of time domain and frequency domain parameters, so no matter what your ultimate reasons for wanting HRV data, this app should be able to provide the data you need. I'm looking forward to the Pro version so I can save and graph the data files as well.

The app looks like it miscalculates essential values. TINN scores on this app are hundred or more times lower than I've calculated with other apps, LF, HF is unlike anything I've seen on other apps, and RMSSD and PNN50 is also invariably lower than I see with other apps (including professional Kubios package) . I would not trust this app until it has been thoroughly tested and verified against a professional HRV pacakge.

Using h7 band. The band is detected but the app doesn't do anything. After selecting my variables it just shows a blue screen with nothing but the variable names. Maybe I'm missing something, like how to start it but it doesn't seem to work.
