User reviews

Perhaps the worst app of all time?

Let's start out by saying I really love the hardware and have been using it for years, but the app, OMG. It is functional in the sense that you get the readings you want to get but it looks like it was designed as part of a high school class project. The hardware is not cheap so I cannot imagine

Nice App!

I appreciate this app for enhancing my awareness of aspects of my well-being that my Apple Watch doesn't track. Highly recommended for fitness and wellness enthusiasts!

良い商品だと思います。

測れましたが、プロフィールで身長を登録したのですが、プロフィール一覧から再度確認すると身長のセンチメーター数がクリアされています。
これはバグなのでしょうか?

Great device but..,

The great and simple device to use. Brilliant actually period. Unfortunately it does not connect to Apple Health app. Which is very unfortunate. It’d be helpful to have all information in the one app.

Useless

App now just crashes so my £100 piece of hardware is now useless. Pathetic.
