ALL AROUND BUGGY‼️

ALL AROUND BUGGY‼️ Have used this app with about half dozen of their products for years and it’s constantly irritating/disappointing and unnecessarily time-consuming to use. Continuous BLUETOOTH BUGS. SYNCING BUGS. Always offline. Settings and device names don’t sync, etc. Tried with multiple iPads and iPhones so it’s on their end. Yes, I am a foot from the devices. Yes, everything is updated. Also readings jumping around as the power button is pressed. IT IS NOT REAL TIME MONITORING. Must launch app and or press the power button to kick start it. SO FRUSTRATING! Please fix these issues already.

Sync issue

The app locks when syncing data to the iPhone. Very frustrating.

Latest update is absolute garbage

App keeps freezing when syncing, causing me to constantly close/reopen. Historical charts older than 30 days are no longer available. Data export is limited to 100 days. And the data saved when I looked this morning was different than what was in the app last night. Terrible UX.

App mostly works

It connects just fine and can update most things about my M10+, but it’s janky. The clock updated when I linked the device, but the AM/PM is wrong and I can’t fix that. The app tries to give useful reference information, but it lacks any numeric reference values. It only tells you good, bad, etc, not a reference of where that value sits in what range.

Also it wants me to sign up for an account, and we should all agree that’s a terrible thing. Fortunately you can skip it and that gets them a third star.

I have to agree to have my data collected now?

Even if I continue as a guest, it requires me to agree to share and allow collection of data. For a temperature app… anyways I just came here to say this and then delete the app.
