Expensive scale cheap app

It’s unfortunate that a company produces a scale of this price point and quality and puts very minimal effort into the software needed to fully unlock the potential of the product.

安定性なし。使い物にならない

スタートしてもスタートしなかったりクラッシュしたり、UIも見にくく、出力するcsvに入力した情報の全てが含まれてないなど、実用的に使おうとしても障壁が多すぎて使い物にならない。スケール自体はいいものだけに、かなり勿体無い。アプリの使い勝手とメンテナンス面で他社製のほうが良いかもしれません。

Crashes, no way to edit water and update profile picture does not work

The app constantly crashes and no way to edit water. Which makes it useless. The idea is amazing but implementation so bad.
