### 5/5 — goood!

*2025-07-03*

I'm using the ExerScale with the the app. It tracks body composition and gives future predictions based on trends. Not sure how accurate the predictions are yet, but it’s an interesting idea. I find the meal logging pretty easy and straightforward. it would be nice to see more features added over time. Looking forward to how it improves.

### 5/5 — Just expected the scale, but cool extras

*2025-06-30*

Bought this for the scale, but the app is great too. Connects with my Apple Watch, has easy meal logging, and the weight prediction feature is cool — really helps me stick to my routine. I hope manual input will be added soon. Looking forward to more features.

### 5/5 — Perfect scale and app for managing my health!

*2025-06-23*

I got Exerchain’s smart scale to help me manage my weight, and I really love how easy it is to check my body composition at home every day using the app. It even lets me log my workouts and meals, which makes staying on top of my health convenient. One feature I’m really into is the weight prediction — it looks at your logs and gives you an estimate. Right now, it’s saying I’ll lose a few pounds next month. Can’t wait to find out if it’s right.

### 1/5 — SCAM

*2025-05-27*

Everything about this company is a scam. They gathered 77K from backers on Kickstarter and even uploaded a fake video to YT to show what this app and their ring supposedly does, which is NOTHING like it actually does. The ring doesn’t track anything but HR, and it doesn’t even do that accurately. Don’t waste your time or money on anything created by these people.

### 1/5 — Doesn’t work

*2025-04-20, version 1.9*

Simply not working and support don’t answer my multiple messages.

### 1/5 — Bad purchase

*2025-04-16*

Please don’t bother. It doesn’t work.

### 1/5 — App has gotten progressively worse!!

*2025-03-23, version 1.9*

The data collection, sync, and historical trending has gotten worse with each iteration of the app for my ring.  Not sure if it is a ring or app problem.  I would have thought these issues would have been resolved during actual user testing.  Very underwhelming experience.

### 1/5 — Not working at all

*2025-03-03*

Never show on my app, unable to connect.

### 1/5 — Doesn’t work

*2025-02-27, version 1.8*

None of the metrics the ring is supposed to track actually get measured or show up in the app.

### 1/5 — No step calculations or TDEE?

*2025-02-01, version 1.6*

Just received the exercise ring, however the app seems to be missing steps monitoring and tdee (total daily energy expenditure).  These are the most important monitors for me.  Please improve the app.
