### 1/5 — 3日目以降連携できず

*2026-03-11, version 3.3.1*

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

### 2/5 — 起動しない

*2025-11-20, version 3.3.0*

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。

### 3/5 — 外部へデータ転送出来れば良いのに…

*2025-01-09, version 3.3.0*

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。

### 2/5 — データ転送出来なくなった

*2024-12-04, version 3.3.0*

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。

### 2/5 — アプリが使いづらい

*2024-09-19, version 3.3.0*

・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

### 1/5 — Apple Health syncing does not work

*2023-06-27*

Apple Health syncing does not work. Please fix.

### 1/5 — 低評価に納得。アプリのセキュリティに難あり

*2021-12-25, version 3.3.0*

iPhoneが生成するパスワード生成に対応していない。
「2台以上のスマホで使用方法に関して」の指示に従うと、一台目に登録したアドレスでログインするように促される。家族で複数人で使うことが想定されていない。セキュリティを考えていない設計であると思わざるを得ない。
bluetooth対応で記録できることを期待したのに買って損した。

### 2/5 — アプリが使いにくい

*2021-09-26, version 3.3.0*

なんだろう、なぜ日本のソフトは使いにくいのだろう。
データの受信というシンプルな話しなのに、迷いどころが多い。
ハード共々もう少し今時のユーザーインターフェースを勉強してほしい。

### 1/5 — 転送機能が使えない

*2021-07-04, version 3.3.0*

データの転送機能がありますが6日程度のデータはアプリで保存されますが以降の新しいデータは転送できません。アプリ側で古いデータを削除しても新しいデータは転送されません。
古いのが残ったまま新しいデータがアプリでは確認できないため転送機能はないのと同じです。
無駄なお金を使ってしまいました。

### 5/5 — 家族の健康管理に最適です

*2020-12-13, version 3.3.0*

現在、両親と同居しております。
父、母、僕と、それぞれiPhoneSE(2nd)を購入して、このアプリで健康管理しています。
血圧計の記録においては、最大5人分のデータがそれぞれのスマホから確認できるので、年老いた両親の健康状態の管理に向いています。
お互いで、健康管理し合っています。
※体温計の記録は、共有出来ないです。パルスオキシメーターは、使ったことありませんがアプリの仕様上共有は出来ないようです。

パルスオキシメーターは糖尿病の管理にも使用できるようで、購入したいと思っています。

使用機種
血圧計
DS-S10

体温計
MT-500BT

今後、追加予定
パルスオキシメーター
BO-750BT

なお、手首式血圧測定器が欲しくてWS-M50BTを買ったのですが、このアプリには対応していませんでした。

アプリ対応の、ビックカメラ専売モデル
WS-X10BTJを、購入する必要があります。
※買い直しました。

WS-M50BTも、アプリに対応して欲しいです。

タニタの体組成計と合わせて、Appleのヘルスケアで一元管理していますが、大変便利です。
Apple WatchとiPhoneSE(2nd)セットで、両親にプレゼントしており、両親が健康管理に目覚めてくれています。

まだまだ、頑張って長生きしてくれそうです♪
