The Dev or manufacturer needs to enable in app to automatically test blood oxygen levels periodically like they have done for the heart rate sensor instead of having to manually do it every time in app. They have made the app work with apple health to share the heart rate but need to make it share its data with apples sleep software to. Definitely needs work and a software update to the ring itself and to revamp the app and add more features in app for the JRing and also the anko Australia ring which uses the JRing application per its manual instructions. ### 2/5 — Stopped working *2026-07-21* Was tracking steps well but within 2 weeks it stopped working and kept giving me a not connected message but it’s connected good thing it’s cheap goes to show you get what you pay for ### 2/5 — 表示 *2026-03-28, version 1.1.6* 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。 改善して頂けると良いかと思います。 ### 2/5 — Won’t work correctly *2026-03-09, version 1.1.6* 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. ### 2/5 — Was great and then not *2026-02-24, version 1.1.6* 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 ### 2/5 — Naja *2026-02-13, version 1.1.6* Warum gibt kein Widgets für das teil es gibt bugs wenn man blutsauerstoff messen will und normalerweise musst das Automatisch messen 🙄 ### 3/5 — fis the app *2026-02-09, version 1.1.6* app doesn’t show nedd to fix asap ### 2/5 — Need an update to work with new OS *2026-02-08, version 1.1.6* The app has stopped working after the latest OS upgrade. An update is required. ### 3/5 — Displayhelligkeit stellt sich immer auf 80% *2026-01-10, version 1.1.6* 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. ### 1/5 — Ring does not connect to app *2026-01-03, version 1.1.5* 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. ### 1/5 — Mauvaise app *2025-12-29, version 1.1.4* L’application n’arrive pas à se connecter à la bague ### 3/5 — App keeps crashing *2025-12-29, version 1.1.4* Unfortunately the app keeps crashing when I try to open it. It worked fine until a few updates ago. ### 2/5 — Schade *2025-12-28, version 1.1.4* Seit dem Update auf iOS 26 ist kein Start der App mehr möglich ### 2/5 — Ok ish *2025-12-27, version 1.1.4* 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. ### 4/5 — 日本語訳が正しくない *2025-12-12, version 1.1.4* クライミングが2つある。サイクリングが正しい。修正を望みます。 ### 1/5 — App won’t stay open *2025-11-30, version 1.1.2* I love this ring so much and have used it for almost a year. Now I can’t get the app to stay open and I have to attempt 20-30 times before it finally opens. Please fix the app!! ### 1/5 — Unable to open the app *2025-11-25, version 1.1.2* The JRing worked well until recently, now I am unable to open the App to read the data. ### 1/5 — Not working on iOS 18.5 - please fix! *2025-11-19, version 1.1.2* Used to work great but now fails to open on iPhone running iOS 8.5. Hopefully the dev team see this and will fix soon. ### 4/5 — Surprisingly nice *2025-11-18* I've only used this a few days, but surprised at how well it seems to sync data with the Apple health app. Sometimes the health app shows a different step count than the app. My wishlist would be if there was a widget that can go on the front lock screen to show step count/other health data according to this app, and not the Apple health app. ### 3/5 — Power levels not accurate on two different menus *2025-11-17* Power levels on Main menu are different to the bar menu, they should be the same, developer pls fix this software bug ## Most critical reviews (10 lowest-rated) ### 1/5 — Rubbish App. *2026-07-27, version 1.1.9* This is the worst app I’ve ever used. There are only 5 choices of sports which include golf and climbing. Where is the gym, pickle, padel and tennis? Cannot find any settings, user manual won’t show on screen and paperwork that came with the smart ring is too small to read. Come on guys this is really basic stuff we need!? ### 1/5 — Garbage *2026-05-27, version 1.1.8* I ordered this ring because it was supposed to do blood glucose. It doesn’t. I was supposed to get two rings as part of the promo, I didn’t. This product over promises and barely delivers. Don’t waste your money. ### 1/5 — Absolutely Sucks *2026-03-21, version 1.1.6* 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!!!!!! ### 1/5 — Constant App crashing *2026-03-14* 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. ### 1/5 — Bracelet doesn’t connect *2026-03-13, version 1.1.6* It works only when charging. ### 1/5 — Reliant on faulty bluetooth connection *2026-03-08, version 1.1.6* 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- ### 1/5 — 起動しても落ちる *2026-03-02, version 1.1.6* iOS26.4に対応していないのか、アプリが起動できません。 ### 1/5 — Ne se connecte pas à la bague *2026-02-10, version 1.1.6* Tout est dans le titre! Et je ne vois pas comment faire. La bague est chargée, mais est « invisible ». Une idée ? ### 1/5 — Une app à revoir *2026-02-10, version 1.1.6* 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…. ### 1/5 — Was never great, but now won’t even open *2026-01-11* 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. ## Most praised reviews (10 highest-rated) ### 5/5 — Good item. But can improvement. *2025-10-21, version 1.1.1* Ring is so good. Linked well with iphone also. But i want to suggest 2 things more. 1. Date display. (Now only time display. But i hope date information also display together. I think just next tab of clock is okay) 2. Simple alarm. Phone call. Or sms message simply notification. If possible i think more useful item. ### 5/5 — Melhorou *2025-09-27, version 1.1.0* Apos a atualização mas falta o tema dark. ### 5/5 — 希望可以有關閉螢幕的功能 *2025-08-23, version 1.0.17* 晚上睡覺誤觸會被螢幕亮醒 ### 5/5 — LED輝度が勝手に変わるのは不便 *2025-07-30, version 1.0.15* 時刻表示中に長押しすると明るさを変えられるが、昼夜輝度Max(100)で使いたいのに、水に濡れたり何かの拍子に長押しされて輝度が変わってしまうと元に戻すのが面倒。リング本体ではなくアプリ側で設定できる様に変更して欲しい。 ↑と書いたら、同期すると勝手に輝度80にセットされる仕様に変わった。余計なお世話でしかない。 アプリのメニューから時間帯毎の輝度を設定出来る様にしろと言ってるの。同期する度に輝度が勝手に変わる機能など望んでない。 ### 5/5 — It Works *2025-07-21, version 1.0.15* I like that it has a “Blood Pressure” and “Sleep tracking” that sync to Apple Health. Please also add that “Blood Oxygen” reading can be sync to Apple Health. ### 5/5 — Great app! *2025-07-13* Two things I would change is the sleep feature and pulse ox. I work nights and it doesnt seem to record my sleep during the day. I would also like it if the pulse ox could take hourly measurements like the heart rate option does. ### 5/5 — Feedback and Ideas *2025-06-26* 我喜歡這個概念和硬體，但軟體有一些我希望集成的主要想法。這也將有助於吸引新的客戶。請為顯示幕和按鈕添加自定義設置，允許我們簡單地刪除其他顯示幕，例如心率或電池，並且只選擇我們也希望能夠切換的顯示幕。或者至少讓我們鎖定一個選項，這樣煩人的開關就不會發生。另一個備受讚賞的功能是完全禁用該按鈕，並始終保持屏幕開啟。保持屏幕開啟的能力將有很大説明。 I love the concept and the hardware, but the software has some major ideas that I would love to be integrated. It would also help bring new costumers. Please please please add a customization for the display and the button, allowing us to simply remove other displays, like heart rate, or battery, and only select the ones we want to be able to switch too. Or at least let us lock one option so that the annoying switch does not happen. Another much appreciated feature would be to disable the button entirely, and keep the screen on at all times. The ability to keep the screen on would greatly help. ### 5/5 — Alles super! *2025-05-07, version 1.0.13* Funktioniert alles super, nach einiger Zeit fehlerhafter und ausbleibender Schlafdaten hat man das Problem jetzt in den Griff bekommen. Alle Daten werden jetzt einwandfrei erfasst, angezeigt und ausgewertet. ### 5/5 — Great track *2025-04-04, version 1.0.11* Best Smart ring app ### 5/5 — Great Health Ring and App *2025-03-12* The ring and the app work extremely well and can be linked to the iPhone Health app. It does measure blood pressure, which shows up on the iPhone Health app, but the reading does not show up on the JRing app. It would be great if an update to the app could correct this. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
