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.
