### 1/5 — よかったけど…

*2025-05-18*

長年使ってきたけど最近ログが取れなくなった日が多くなった気がする　
見直したい日に保存されてないと本当にガッカリ
アプリ自体は表示もスッキリしててすごく見やすいから使い続けたいけど…

追加:写真が全く保存されなくなりました
問い合わせもしたけど返事なし
やる気ないのかな

### 4/5 — 歩数表示のラグ

*2025-04-21*

movesや僕の来た道に代わって便利に使わせてもらっているが、最近？日付指定で歩数確認すると表示してから2〜3秒おきに1回、2回と歩数が増加していく現象が発生している。煩わしいので歩数の計算だか参照だかに時間がかかるならずっとローディングにして一度で結果を表示してほしい。

### 2/5 — フラストレーションが溜まる

*2024-10-22*

使っていて気になる点が大きく2点あります。

・信号待ち程度の時間すら「滞在」カウントになり、一日のタイムラインが見づらい。徒歩の時間に含めてほしい
・立ち寄った店の名前を一度登録すると、後日その周辺で立ち止まっただけでも自動でその店に行ったことになってしまう。手動でその記録を消す必要があり、かなり面倒

アプリ内をくまなく探したつもりですが、この点を変更できるような設定項目は見当たりませんでした。

### 1/5 — Life Cycleというアプリが英語だからと思って使ってみたものの使いづらい

*2024-10-03*

Apple Watchでも使えるということでダウンロードしていちどは使ってみたことあるけれど、利用規約とプライバシーポリシーを確認して同意しますをタップすると、プライバシーポリシーが出てきて先に進まない。VoiceOverを使っているから進まないのかどうなのかがわからないけれど、詳しく状況を教えてとデベロッパーガーから返す前に、iPhone 15を使っているのでそれを使って試してみて欲しい。

### 1/5 — データが消えるアプリは論外

*2024-08-24*

長年バックグラウンドで動いてくれましたが、ある日データもアカウントも全て消えてました。
アカウントはどこにも保存されてないので、回復不能のようです。
データの転送が1日分ずつなも不便
クラウド等への自動保存や一括保存の機能は必須だと思う

### 4/5 — 月表示の年月

*2024-08-15*

日付をタップするとカレンダーが表示されますが年月の表記がiPhoneのノッチに隠れてしまい、遡っていると何年何月だかわからなくなります。アプリスイッチャーで確認はできますがカレンダー&年月をノッチの下まで下げてもらえるとありがたいです。

### 2/5 — 0表示

*2024-07-12*

何らかの理由があるとは思うけど、ログがとられていなくて、0表示になっているときがある。通勤しているのにゼロはないわけで。

追記
なるほど、本体を再起動した場合はアプリを起動しなければログをとることができないわけね。要注意。

### 1/5 — うーん

*2024-07-11*

昔のスマホで使ってたのを思い出し、インストールしました。
新しいアカウントを作ろうと思い必要情報を入力して アカウント登録 のボタンをポチ…と、登録に失敗しました の文字…
最近のレビューを見るとバグも多いらしく、使うのやめようかなぁとなりました。

### 5/5 — 去年の母の日どこ行ったっけとか

*2024-05-12*

過去の記念の日にどこに行ったかなど調べるときに非常に助かります。
難点を言えば、過去に遡るときに年ごとにカレンダーが移動できないこととです。
カレンダーが表示されたときに年をタップすると過去の年が数年分表示されて選択できるととても良いです。

### 1/5 — 記録がつかなくなりました

*2024-04-03*

前は放っておいても記録がついていました。しかし、いつ頃からか記録が0のままに。しばらく改善されるかと待っていましたが、どうやらダメな様です。昔はできていたことが出来なくなっていて余計な機能がつくというのは、私的にはなしなので、端末上からなくすことと致しました。
