## RingO2 Reviews in United States

### *---- "This app is a fake. Do not download!"
This app uses a name similar to a real product.  It does not work, at all.  This is a cheat.  The app should be removed from the AppStore. 

Could not give a zero rating.
-- zand78, 2024-11-08

### *---- "Ditto"
Will not connect with app by the same name. No relevant instruction manual. Cheap knock off of a basic pilse oximeter IMO.
-- pO2-nyet, 2024-07-07

### *---- "Please reinstate this app!"
What have you done to this app??  I had years worth of data and now it’s gone! I tried to reload it and it won’t connect to my Bluetooth. Please fix the problem because I depend on this ring every night.
-- Words R Enough, 2022-12-24

### *---- "02Ring LOOKEE - DON’T Purchase"
ZERO - Rating But that’s not an option 
And it should be
Will not connect to the app. DO NOT PURCHASE!!!! 2Ring Wearable Oxygen Monitor. Can’t call LOOKEE for support you have to send an e-mail and WAIT fir them to respond. For  $169 it should work just as LOOKEE claims it will and it will NOT CONNECT TO THE APP. DO NOT PURCHASE!!!!!!!
-- ShootingStar.05, 2022-10-13

### *---- "not for Wellue Ring"
Not sure what device this is for, but not the Wellue Ring, as others have also pointed out. The app for the Wellue Ring is ViHealth, get that and all will work fine.
-- catawboy, 2021-12-05

### **--- "Will not work with Ring O2 app!"
Like everyone else says it absolutely positively will not work with the app that shares its name and it’s logo. The whole point of this device is to record its results through the night and that’s the purpose of the app and it will not connect to the app, I’m giving it to stars instead of one because if you do some detective work you can discover that it works just fine and as intended with an app called V hi health, go figure, download that app and it connects immediately and works as advertised.
-- nevadagame, 2021-03-31

### ***-- "You need the ViHealth App for O2ring"
This is not the right app for the O2ring as I found ... will not link with ring. As soon as I used the ViHealth app it is great. This
-- Raemax73, 2021-02-15

### *---- "RingO2 app"
App wont connect to device . I deleted useless app.
-- acdoc1, 2020-09-24

### ***-- "I dint check before I purchased this"
If only I had.     Just like everyone says, it won’t work.  It wasn’t connecting to Bluetooth.  I left a bad review.  I’m Truly sorry, I had downloaded the wrong app. It was an honest mistake but I want everyone who reads this to double check, maybe you made the same mistake. 😔
-- GTB Ranch, 2020-07-30

### *---- "Wrong app"
This the absolute wrong app for the well ue 02 ring device. Bluetooth WILL NOT work with this app. I learned this the hard way. The correct app to use on an IOS phone anyway is called VIHealth.
Works like a champ too.
