Please stop changing my settings
I think this is a good app. It does what it's intended to do. I do have slight apnea that isn't severe enough to treat. But I do monitor in case it could get worse. My O2 does dip very occasionally and very quickly below 90%. I set my O2 reminder at 80 because I do want to deal with that. But the app keeps changing it to 90 and I get awakened which is not good with my sleep disturbance issues. Very hard to get back to sleep. Please just stop trying to be my overlord and let me have my setting. I don't remember to check every night to see if you've switched it up on me again. My health is not served by waking me up. I need my sleep but I want to monitor. You're making that difficult. I think I may need a repeating calendar entry to remind to check and see what settings your app changes because you think we're all the same and need settings based on the herd. I need my individual setting left where I set it.

App loops and doesn’t download well
The app loops while trying to download data from the device. If I cannot get the device data, it is worthless.
Will not connect.
Can’t connect to Bluetooth. Sitting here right now trying to get it last nights o2 reading and nothing is working. Paid $139. For nothing. Thanks for this trash. Tried everything.
Alerts need added features
Right now the app will vibrate your wrist or your phone when your Blood Oxygen reaches below a certain level, but there is often a lot of quick fluctuations (sudden drop that goes back up immediately), so it would be more helpful to be able to turn on an alert that notifies me when blood oxygen is below X% for X amount of seconds (like below 90% for over 10 seconds).
Also, I am very disappointed that the Bluetooth range of the device is so poor. I have to have my phone literally next to me in order for the device to stay connected.

bad update
latest update the app won't open for an extremely long time, sometimes not at all. tried rebooting and offloading but nothing helps.
Not good with multiple devices
I have an O2Ring and now a BP2A. When using multiple devices, this interface is awkward. Every time I want to switch devices I need go to my profile and select the device that I want to use. Every time. Why can’t I just pick up a device and use it without needing to push several buttons. I am not convinced that having one app for two different devices is a benefit if I need to push several buttons to select the device I want to use every time I use it.

App no longer loads
For the past two weeks, the app is taking longer to load. today It will not load at all. I don’t know why please fix.
Not reliable at all
For a health app the one thing you want is reliability. Sporadically it cuts off, won’t analyse and despite obvious ectopic heart beats says I’m in normal beats. It’s so disappointing to have an expensive chest strap monitor only work through such a faulty app. Contacting customer service is a waste of time as they never reply.

App crashes frequently
I’ve used this app for several years now, and have found it useful.
However, since the recent update, it fails to load, often requiring several restarts to get it to open.
Restarting the iPhone doesn’t fix the problem.
It doesn’t show all the data for the Oxylink ring I have. I know this because the data will upload to my computer, using a program called “OSCAR,” which I use to track CPAP data.
It also misses citing O2 drops, yet shows these in the displayed waveforms on the iPhone. I’m using iOS 26.5.
This app worked reliably before the last update.

To allocate a user
I had to add a second fictional second user and choose myself as user 1. And “Jo” as second user. This solve many issues. Graphing of blood pressure seems good. Time will tell. Will update after I use app more. Using a Check Me monitor.
Pretty useless
Thus software tells you little practical information. O2 stats, but you need to submit the readings to AI to make any meaningful sense out of them. Eire is the paid subscription. Utter, valueless garbage. Tells you nothing useful.
Using app with ECG recorder
The one channel ECG (with display) streams live data to the app. This works quite well when the signal settles down, and there’s an option to do a fast acquisition for a max of 30 minutes. But the device is capable of recording for 24 hours. I was assuming that the data was captured and could be synced when not in the fast acquisition mode. After a slow sync process via Bluetooth, the files are nowhere to be found in history in the app, apparently can’t be exported, or even viewed in the documents folder.

No Longer creates files that can be imported into Oscar
The app used to work fine with my Wellue ring, and it kind of works with my new O2Ring S, but it no longer creates a usable binary export file that will properly import into Oscar or Oscar2.0. With Oscar it immediately crashes the program, and with Oscar2.0, it seems to import, but the data is not there.

Features
The app is great for how I use it. Blood Pressure and ECG from a BP2 device. The files are easily saved as PDF or CSV. One feature with the app that would be great is to write the ECG data to Apple Health. The Blood Pressure data goes in seamlessly, and having the ECG readings in there would be fantastic.

Wonky Data
This app loses data from day to day. I have been downloading it, thankfully. As an example, over the last week it dropped 2 days worth of info and hallucinated 2 sets of data for the same night. Who knows what info will still be there tomorrow?!
Frequently disconnected
In practice the device will disconnect once an hour from the app. It does not reconnect even in ideal conditions where the phone is in the same room with no other devices. Impossible to get a full nights data.
Device only has one strap. This is not enough to secure it to the child’s finger. Owlet for example has 2 straps.

Bluetooth worked once
Now device is always Disconnected, and won’t reconnect. Doesn’t show up in scan either.
Always crashes!
Every time I invoke the app now, it displays an app-launch screen for a second, then crashes. Dead!! Nothing!! I’m very frustrated and angry with this app and its developer.
No issues yet
Installed this app on April 20, 2026 and have had no issues with either the PC version (O2 Insight Pro)or the iPhone app. Data is coming from the Wellue O2 Ring S.
