以前は、スマホと同期していた酸素濃度、心拍数が表示できなくなっています。現在は、睡眠時間のみです。

Absolutely Sucks

Never Ever Download This App Or Purchase A JRing….
It Only Works For A Few Days & That’s It. It Won’t Pair To Your Phone & It Stops Counting Steps.
It Never Gives You Your Sleep Number, Again! Never Ever Purchase A JRing Or Download This App!!!!!!

Constant App crashing

A purchase I really regret. App constantly crashes with a 20% chance it opens, there is no way to reconnect the device to the phone if it becomes disconnected unless it’s put on charge again.
Overall you get what you pay for.

Bracelet doesn’t connect

It works only when charging.

Won’t work correctly

I tried it out, and it sucks. I have an app that syncs my fitbit (because it’s better than an Apple Watch) to my Health Data on my iphone. The JRing is supposed to connect with my Health Data and it doesn’t update. All settings are on. Still doesn’t work. Yesterday it said i walked 425 steps. I actually walked over 7,000. This thing sucks. Don’t get it. If it’s not made in USA then it sucks.

Reliant on faulty bluetooth connection

App sporadically connected and constantly disconnects from Bluetooth connection making it unreliable and terribly frustrating - I do not have this issue w Fitbit and Oura devices-

起動しても落ちる

iOS26.4に対応していないのか、アプリが起動できません。

Was great and then not

It tried for months and then all of a sudden it uncombined itself from my phone so I could no longer track DATA or keep the right time on the ring

Naja

Warum gibt kein Widgets für das teil es gibt bugs wenn man blutsauerstoff messen will und normalerweise musst das Automatisch messen 🙄

Ne se connecte pas à la bague

Tout est dans le titre! Et je ne vois pas comment faire. La bague est chargée, mais est « invisible ». Une idée ?

Une app à revoir

Autant la bague est jolie et facile à porter, autant l’application est à revoir! Les donnes sont approximatives, les traductions nulles , et surtout aucune possibilité d’avoir une simple notification qui indique que qu’il n’y a plus de batterie! Donc on se retrouve avec des jours sans données….

fis the app

app doesn’t show nedd to fix asap

Need an update to work with new OS

The app has stopped working after the latest OS upgrade. An update is required.

Was never great, but now won’t even open

The ring is great, but this app is not. It was ok, then had issues opening, now won’t open at all. It does me no good when I can’t see the information!
UPDATE: deleted and reinstalled and it opens now, but will not connect to either of my rings. They connect to Bluetooth with no issues, but the app will no longer connect with them.

Displayhelligkeit stellt sich immer auf 80%

Die App ist teilweise schlecht übersetzt und Man kann sie nicht im Hintergrund laufen, denn dann. Ist der Akku vom Ring sehr schnell leer. Das sollte vom Entwickler mal überarbeitet werden.

Ring does not connect to app

Out of the box it worked well. A week later it disconnected from app. I’ve tried to reconnect. The ring shows up on available devices but will not connect to the app. Because of this the ring is useless for my purpose.

Mauvaise app

L’application n’arrive pas à se connecter à la bague

App keeps crashing

Unfortunately the app keeps crashing when I try to open it. It worked fine until a few updates ago.

Schade

Seit dem Update auf iOS 26 ist kein Start der App mehr möglich

Ok ish

Works fine on the SR08. But there are issues with the SR16. 1/. Firstly, when charging, the ring shows 0% instead of 100%. It goes to 99% then 0.
2/. Also, the app cuts out after you exit each tab.
3/. Sleep monitoring is not even close.
4/. It does not download O2 data from the ring, and there is no way of setting a timed O2
Measurement.
