The worst part is that if you switch between female and male, the data doesn't change—the threshold for being thin remains the same in both cases. The graphics are also of poor quality since you can't adjust them horizontally, and they don't give you a clear idea of your progress. ### 1/5 — 記録 *2022-07-22, version 1.2.8* 突然記録出来なくなりました 対応よろしくお願い致します。 ### 1/5 — App needs an update *2022-06-19, version 1.2.8* The app will no longer allow new users to be added nor can anyone register a new account. Seriously needs an update or devices become unusable… ### 1/5 — 急に使えなくなった *2022-05-31, version 1.2.8* 息子と一緒に別々のスマホで使用しています。私の方は問題なく使えますが、息子のほうが使えなくなりました。正確には息子の計測が私のスマホに飛んできます。私の方のアプリを閉じていても、私が計測するとホーム画面にベルのマークで息子のデータの蓄積を知らせてきます。（息子のスマホには計測されていない） そもそもアプリにメールアドレスを紐づけているのに、個人を識別しないのが不思議で仕方ないです。 アプリから問い合わせましたが不思議な日本語訳の返答でした。 私がiPhoneで息子がAndroidです。他の方のレビューにもありましたが、これは何か関係があるんでしょうか。 息子のために買ったので、私は一旦アンインストールしますが、この謎ルールだと私はアプリを持っていなくても私の計測は息子のスマホに飛ぶのでしょうかね？家族といえど嫌ですね。 2022/5/31追記 ついに息子のスマホともペアリングできなくなりました。 計測してもアプリが反応しないので、アプリのログアウト、アプリのインストールし直し、スマホの再起動、Bluetoothの再接続、デバイスとの再接続、いろいろやりましたがダメでした。 と思ったのですが、本体の電池を一度外して入れ直したら復活してくれました… ダメ元だったけど信じられないくらいアナログな方法で復活したので拍子抜けしました… アプリが反応しなくなった方は一度お試しください… ### 3/5 — データの反映出来るようにしてほしい *2021-08-16, version 1.2.8* 5月10日以降、データが外部（ヘルスケア）に、反映出来てません。なので、更新して不具合直すのを希望します。それ以外は、とってもよいアプリですね！すごく計測も早いし、グラフも見やすいし！ ### 2/5 — グラフ改良してください *2021-08-05, version 1.2.8* 各項目を計測はできるが、グラフ化できるのはたった5項目程度のため、推移が分からない。全項目グラフ化対応してほしい。使いにくい。改善求む。 ### 1/5 — 詐欺 *2021-05-22, version 1.2.8* 買って1週間で全くBluetoothが繋がらなくなったが？ そもそもアプリ内でしかBluetoothに繋げないって仕様のせいでユーザ側で原因特定する手段が皆無なのおかしいだろ 舐めてんのか？ ### 2/5 — iPhoneでは使える *2020-11-03, version 1.2.5* 良いです。毎日記録して助かっています。 が、Androidでの使用が突如できなくなりました。アップデートでもないようですが何故でしょう？ 運営さん、ご対応よろしくお願い致します。 後日追記 家族2人で共有しています。iPhoneとAndroidで。Androidが動かないのは、どうもiPhoneの方に反映してしまっているようです。なんとかなりませんかね… ## Frequently asked questions about F ### How does F-Tracker help with weight goals?
