I had to call for assistance, and, Pilar was extremely friendly and helpful I would not have been able to do this without her guidance. She made this so easy. Not because by no means is it hard but because I'm not very computer savvy lol. It was rather easy once I was shown how to do it. Thank you, Pilar!

Not sure about others having a 1-star experience, but this worked perfectly fine for me! :) Did what it was supposed to do. No ads.

The app does not show past recordings as stated in the manual. It shows the last recorded time, and it shows complete, in green. However, I saw a 1/2 sec message on my screen once I hit stop recording saying the session was too short. In the manual it says it may have been under two hours. I put it on when I went to sleep and took it off when I got up; just under six hours. The issue is that I was awake for a couple of those hours, so it stopped recording! It's supposed to tell me why I'm up!

Installed app with CPAP supplier tech for home sleep study, including pairing Bluetooth pulse-oximeter on a Moto 5G 5 2022 phone. No permissions were restricted, sufficient storage, battery life sufficient. After completing both sessions, the recordings are supposed to be kept. After processing ('completed'), both times, during sending, the app gave an "Error processing" notice with no options except to return to the main screen. Neither session was sent or kept.

Extremely buggy and poorly designed. App recorded one night of data then refused to let me record another, and the only option that it gave me was DELETE THE EXISTING DATA AND USER ACCOUNT. Whoever designed this should be fired.

The app is terrible. Continually closing out when trying to launch. Woman at sleep center said it's very hit-and-miss with Android devices. Thankfully I was able to get it to work on my wife's iPhone. After completing my sleep study (6+ hours of data) it got stuck on the Processing screen. The app says it can take up to 5 minutes to upload your study. Mine took close to an hour. I was convinced I was going to have to redo it. Give it time, and hopefully it will upload your data.
