User reviews

3日目以降連携できず

データ受信できたとのメッセージが出るが、連携されず。便利の機能なのでなんとか動くよう改修してほしい

起動しない

iOSをアップデートしてから、血圧計も体温計も、タップしても起動しなくなった。一度アプリを削除してパスワードを入れ直せば一時的には正常に動くものの、しばらくするとまた凍りつく。困りものですな。

外部へデータ転送出来れば良いのに…

メーカーに問合せても返答が無いとの評価だったが、メーカーのホームページで問合せした当日に回答が届き、問題が解決した。
取り込んだデータを医療機関へ送れるとなお良かった。

データ転送出来なくなった

突然測定データがスマホに転送出来なくなりました。メーカーに問い合わせても回答が無く、アプリの問題なのか本体の問題なのかが分からずイライラさせられます。

アプリが使いづらい

・機器とアプリのBluetooth連携を、機器の立ち上げの度に一々手動で接続しなくてはならない
・アプリ上でデータの削除の操作ができない
