I woke up the morning after night 2 to a notification about how the study was interrupted with no elaboration as to what happened. The app has zero way to see what went wrong and spitefully dropped all data it would have collected beforehand rather than doing the obvious and sensible thing of at least saving what it could, and at 25% battery with the ring there's no way another night is possible.

Absolute trash. I can't believe doctors use this. The app closed on me two nights in a row. when I launched it the second night it had the nerve to tell me it was because of power. I plug my phone in every night. Each night I only had two apps open. My alarm app and this app. The second night I was extra careful and it still closed. I'm pretty sure it's a scam to get the late fees.

App/device failed across 3 nights. It paired, then repeatedly lost Bluetooth/app connection before required recording time. Longest session was ~1 hr 40 min; most failed within 40 sec–2 min. Tried reboot, foreground app, screen on, no other Bluetooth devices, airplane mode + Bluetooth, uninstalled possible conflicting apps, and a second Android device. Same result. Support said return for replacement, but no cross-ship, creating a delay for a medically ordered sleep study.
