It syncs for hours and hours and nothing ever happens. I’ve deleted the app and restarted multiple times. The instructions provide no guidance regarding the sync process. I’m very frustrated. The ring is useless since I can’t get the sync to complete. ### 4/5 — Sensible *2024-07-18* A very affordable alternative to $300+ rings. More reliable than <$100 rings. Like that the app is available on iPhone and iPad ### 1/5 — Terrible product and customer service *2024-07-01* I got my ring in April of this year (2024) and it worked great for the first two week. Then I had issues charging it. I contacted customer service no response. I still continued to have issues charging it but I would eventually get the ring to charge to 100%. Now it’s not holding a charge. Contacted customer service again, no response same as last time. I charged it for 4 hours this morning because the manual says that resets the battery. It’s been off the charger for 3 1/2 hours and it’s already at 53% contacted customer support again for the 3rd time and guess what, no response. What a waist of 250$ **Developer response:** Dear Jennifer, Thanks for your valuable feedback.

JCRing Development Team ### 1/5 — 淘寶客服態度惡劣 / Terrible customer service on TaoBao *2024-05-23* 客服人員態度惡劣，售後的服務完全不及格，任何問題一率不回應，這樣的公司我認為不應該用金錢肯定他們，你有更好的選擇。 The customer service staff have a bad attitude, the after-sales service is completely substandard, and they will not respond to any questions. I don’t think you should give money to such a company. You have better choices. **Developer response:** 您好，感谢您对JCRing的关注！敬请知悉我司淘宝上货物暂不支持发货到港澳之外的其他海外地区，客服为平台系统客服，很抱歉给您造成困扰！ Hello, thank you for your attention to JCRing!

We apologize for any inconvenience this may have caused you! ## Most critical reviews (10 lowest-rated) ### 1/5 — Leaf Support *2026-07-11* Pathetic support from Leaf and they even don’t have direct support line. Making all conversations via email. Don’t buy this ring at all ### 1/5 — It’s third party app *2026-06-18* It’s third party app… no reply from complaint ### 1/5 — Read before you buy this ring *2026-01-19* Know that if you buy this ring and experience any problems at all, your investment is wasted if you can’t get the developers help. You will own a dead piece of electronics. Now, if the developer responds to this quickly and appropriately, you can choose how to proceed with making a purchase through this company. otherwise currently, I purchased this ring and it will not connect, and that makes it a bad investment and completely worthless! ### 1/5 — VO2 Max *2026-01-16* There is no VO2 Max parameter in the health section. Has it been deleted by the app development team? ### 1/5 — Leaf ring *2025-11-22* Waste of money App also dont belong to leaf ### 1/5 — Removal of Sugar levels *2025-11-21* My main purpose of this ring was the its testing capability of sugar levels. This has stopped ### 1/5 — i cannot log in *2025-03-03* i tried logging in or making a new account and still it won’t work ### 1/5 — Rip off *2025-02-16* At first, it was great. Unfortunately firmware and software updates make the ring useless. Customer service only responded after multiple messages over a month. When they responded, it was just copy and paste general responses. Nothing worthwhile. ### 1/5 — Not working after update *2025-02-14* Ring was working earlier but after recent firmware update the ring stopped working ### 1/5 — Not working *2024-11-10* The ring is not tracking or Not working at all after firmware update. ## Most praised reviews (10 highest-rated) ### 5/5 — Great ring and connectivity. *2025-11-03* I am enjoying this ring and its great connectivity and functionality. It connects to a lot of health apps. In the last week, when checking blood glucose, the initial report says LOW but the weekly chart is showing marginal. Is there a way to correct this? ### 5/5 — Exercise *2025-07-23* I love this ring, but you need to add swimming to the exercises. ### 5/5 — Nice ring and great looking app *2025-05-31* Overall I like the smart ring and app, I wish time was not in military time but instead 12 hour time. That’s the one thing I wish could be fixed and to not lose my data. I like how it syncs to Apple health. That allows me to store my health data. I like the app logo design. I like how it looks like the Apple Watch app logo design. Do not change the logo. App is nice but wish I could have this fixed. ### 5/5 — Awesome *2024-12-02* I love my ring. More affordable than most it does exactly what I want. ### 5/5 — Very good *2024-08-24* Comprehensive features, simple and fluid! ### 5/5 — Highly recommended! *2024-06-07* The JC Ring app is incredibly professional and user-friendly. It offers precise data and valuable insights, making it an essential tool for anyone using a JC ring. Highly recommended! ### 5/5 — Very nice app *2024-06-07* One of the best ring app now I have tested, sleep accuracy quite good, I really like it a lot ### 4/5 — Blood glucose *2025-10-17* No blood glucose levels after update. Please advise. ### 4/5 — Glucose risk assessment is not appearing *2025-10-03* After recent update, Glucose risk assessment is not showing up. Does it have different navigation? ### 4/5 — Works fine *2025-01-15* Great app, works fine. Simple and easy to use. A copple of bugs in blood sugar detection and VO2MAX analisys. Please fix the bugs, Thanks! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
