This seems to be a pretty good app. I got the Wellue O2Ring device and it pretty accurate. But the app does NOT link to the Google FIT app, and (even worse) it has no data export function. And no, I do not think that a screenshot counts as data export. If the data was transferred to the app, why can't I export that data to a CSV text file for example? If that feature is added, that will push my rating to five stars.

I use as an ECG monitor. With this last update, it continues to tell me my device is offline. If I let it set for a minute or so it "may" find it, but then it will frequently drop it, even when sitting still, changing nothing, and it may or may not find it after closing and trying again. It didn't use to do this. It did used to randomly tell me it was offline, but I could usually close it and try again and get quick results. Now it's just frustrating. I hope it gets fixed soon.

I'm not sure why so many 1 star reviews. The Wellue O2Ring itself is great. I wear it all night and the next day I plug it into USB charger and check my results. The ring recharges fully in about 2 hours after using all night. The app is good but could use improvements. They just added CSV export! Features i would like to see: ability to add label to the recordings, and ability to limit vibration time. FYI, the app works in airplane mode with bluetooth enabled, if u don't trust developers.

This is very well written app. Although I read some reviews about BT connectivity I also have enough BT experiences to know that the fault is most often with the phone and not the app. Other apps can interrupt the running program with an IRQ that causes a disconnect or 'unpairing' to occur. These same poorly written apps can also prevent another device from connecting as long as they're running even in the background. I also have concerns about apps needing permission to access my files and photos but upon lengthy research I found that these types of apps need access in order to write to files, access memory and record data because they couldn't fulfill their function without these permissions. So I decided to try the app out. It's really amazing and well written. I can monitor my HR and O2 levels during HIIT and VIIT sessions and I can save my recorded sessions to show my doctor and for future comparisons during and after exercises to show improvements and deficits. I believe this app and my Wellue device will help me achieve my fitness goals.

Got this for use with a smart scale. This is one of the worst apps I've ever used. It barely functions. Scale doesn't remember lb/kg preference. The bmi scales are broken. Instead of a simple text input for goal weight, they used a custom dial input that is impossible to be exact with. It's mind boggling, considering how basic this app should be (just weight history).

Latest update of the app made absolutely every single aspect of it worse. It is slow, unresponsive, takes a minute to connect to the device EVERY time you open the app. Now it also REQUIRES internet connection to even open. I lost every note on the recordings I had on the phone, some recording I had deleted popped up again, and any recording longer than a couple minutes takes about 5 minutes to even open. Please revert this app to its old state or at least provide the old APK to sideload it.

I saw there was an update and I was hoping it would fix the ongoing problem of not connecting and crashing. I updated the app and tried to open it. It no longer crashes, but now won't open at all. It has made my blood pressure monitor with ECG basically worthless because I can't share the much needed information with my cardiologist. This was an amazing app until the last update. Now it crashes before ever opening. And every review I've left about this has been deleted!!!

So far, I've had no problems with the app. It seems to work fine. I thought it was going to upload data from the PulseOx when readings were taken offline, but it only stores readings taken while the app is running in real-time. My one suggestion so far, is that I'd love to be able to export all of the data in a report. You can only export a single entry at a time, and can't export all of the data, or even the graph of your O2/Pulse measurements. This seems like a big miss. I want to print out a graph, or a list of data points to show my doctor.

Since the app was updated on August 24 or 25, all the numbers appear in the wrong boxes. The ranges and actual numbers dont match at all. Very huggy app. Was working ok until yesterday. Update: I have beem emailing with the company for a couple of days and sharing screen shots, offering suggestions, and requesting software updates. The company has been extremely responsive and very quick to make software updates. I am very pleased to see the company so helpful & quick to take action. Thanks!!!

Love that my oxygen level is ALWAYS accessible. As a person with comprised lungs it is important to have prompt data. I had a bit of an issue learning to connect to my phone. My other problem is that although the device is supposed to convert to 12 hour time automatically it almost always is 24 hours. I don't see VA seeing to change it.

So far, so good. My son has Reactive Airway Disease and tends to have problems everytime he catches a cold. I tried this on him last night and it performed well. There was some add-on specific to the oximeter ring we have, so I downloaded that as well. Not sure if it does anything. But, the app stayed on and alerted me when his O2 dropped or the ring fell off, as per my settings. So far, I like it. It means I don't have to stay awake all night worrying, which is great.

It's a decent app that shows heart rate, oxygen, and motion. You can look at old recordings or see the current values. The pinch gestures to zoom in on the graphs are nice. Problem: If you have more than a few months of data, the History list will not respond for 10-15 seconds until it has loaded every single recording, even though only 5-6 recordings are displayed at a time. It does this after every single task you try to do with the History list. It's poor programming and needs to be fixed.

Device will not stay connected via bluetooth. Have to delete device and re-add to sync every time. My phone indicates that this app is not compatible with the most recent version of Android, so that might be part of the problem. The app also freezes/gets stuck on one screen. So, overall a bad experience. Two stars because the data is very useful and I've been able to force it to work with workarounds, but overall this app needs an overhaul. The csv data export also has problems.

App has a good UI. It shows live readings when the user inserts a finger in the pulse oximeter, and records until the user removes the finger. The display is large and easily read. At session end it presents a summary and stores the readings. No login or subscription is required for local storage. The history allows filtering by date, but not by reading value(s). It makes a loud beep on device disconnect, which I wish were configurable. Bluetooth setup with the device is effortless. Nice!

I bought the O2Ring S for its 1-second resolution and long battery life, and I’m very impressed. It clearly shows how often and how long my O2 levels drop below 90%. With vibration on, the ring gently alerts me, and my levels quickly return to normal—without waking me up. My only gripe is the size: I have large hands, and it only fits on my pinky, which may affect accuracy. Even so, the data seems reliable. A great, well-designed device overall.

UPDATE: App has been fixed! Latest update breaks app. The app is trying to force you to create an account and store your data in the cloud. It prompts multiple times on app startup eventually crashing if you keep declining. Also crashes now when connecting to the device via Bluetooth. I can still manually add the info after restarting the app 2-3 time. App was working very well prior to this last update(5*)

May 2025 - I tried it again hoping it would be better. Now the app requires location access to even start. It is collecting data it doesn't need. Terrible. The update (Dec 2022) is TERRIBLE! Before I was able to switch between multiple devices. Now I can't access the MONTHS of health data I have accumulated. It is now demanding an account be created and trying to bypass that is an absolute headache. Within minutes I already had an advertisement in the way. The app is now USELESS.

This app lets you turn vibrations on, but it does not allow you to turn them back off. The minimum oxygenation threshold this app allows you to set is 80%. I had planned to turn vibrations on if I went under 70%, but I turned vibrations on and then went to set the percentage, at which point I found out I can no longer use my O2 ring because this app won't let me set the oxygenation threshold low enough and won't let me turn vibrations back off.

Since Upgrading to a BP2Connect I get unassigned data. This happens at least two to 3 times a week. I even wait until it shows up in history, but the next day it is unassigned. Since I am the only person who uses both my phone and the BP2Connect this is becoming a big issue. It doesn't transfer to Google's health connect or Samsung Health when it remains unassigned. months later and nothing has changed. I will be dumping all my current devices that use this app for devices that actually work!

The first year was fabulous. Worked perfectly with my phone. But after time, the device stopped connecting to the app. No matter what I do, I cannot get the two to work together anymore. It's too bad, because it was an excellent device. And when it did work I could easily email a log of my vitals to my cardiologist from my phone. Please, help me reestablish the connection between the device and the app.
