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.

App crashes often
I am grateful this exists because nothing else on the market does to monitor my son’s epilepsy when he’s asleep. My one star is because I’m a power user that has been using this for a long time and every time I reach out to customer service, I’m lucky if I get a reply and when I do (after I reach out again) they tell me it’s not their fault. The app crashes 1-2 times a month on its own. So the coverage I think I have to keep my son safe crashes and I don’t know it’s happening because it’s always at night. That’s my biggest heartburn I want resolved. Other nice features to add would be able to actually see the O2 and bpm in real time via bluetooth as that only works if you’re in the room with the device. And being able to have access to the controls such as on my phone as it’s connected to the phone in my son’s room (like an Owlet sock) would be amazing. Like I said there isn’t much on the market for children with epilepsy so you’d find you’d get a lot more customers.

Update makes app nonfunctional
Dead app
Great app!
This is a great app! I use it on my iPhone to check the results of wearing my Wellue O2Ring while I sleep. The data transfer is quick & easy and the graphs provide a good means of scanning the nights results. I’ve had no problems with this app whatsoever!
Struggles To Download Data
WAS a reliable app. Ever since the latest update, it struggles to download data from the O2 Ring. Repeatedly, starts and stops data downloads multiple times before finally completing. I have to piss in the morning and don’t have time to wait.
Not Syncing
Goes halfway then stops then repeats but no data is transferring
No longer works
No longer works after yesterday’s update. Will not download from ring.
