### 1/5 — it used to be good

*2025-09-26, version 3.2.22*

recently unstable

### 5/5 — 地図表示すると中断するようになりました。

*2024-02-21, version 3.2.19*

トラック中に、これまでの移動経過を地図で確認すると、地図から戻った直後にトラック作成を中断します。再現性あります。１日安心して動作するよう、改善をお願いします。

### 3/5 — 動作不良？

*2023-05-02, version 3.2.19*

Eメールでトラックエクスポートが出来ません。機材は、iPhone13(iOS16.4)にてログ作成→@yahoo.co.jpへメール送信出来ません。以前は出来たのですが、、、もちろん、iPhoneのリセットとかは一通りやってます。ちなみに、10回に1回位送れます。

### 1/5 — 勝手に止まってしまう

*2022-11-02, version 3.2.18*

2022/1/4追記 しばらく調子が良かったですが、また止まってしまいました。 以前改善されたとのお話でしたが、まだ勝手に止まってしまう問題はあるようです。 2022/10/11 また止まりました。2022/11/2 また止まりました。

### 1/5 — はっきり言って、最悪...

*2022-08-27, version 3.2.18*

買取だと思って購入したら、いつの間にか、
サブクリに変更されていてました。
月初に期限だったので解約しようとして、
説明を読むと不明確...
さらにサポートに連絡するも未だに返信なし。(既に5日経過)

### 2/5 — ログがとれない事がある

*2022-04-09, version 3.2.16*

原因、理由はわかりませんが、肝心の時に限ってログが記録されず、出発点と到着点が直線で結ばれる事があります。記録を残しておきたい時に限って、が多いので困っています。

### 5/5 — gpsが途切れる問題

*2022-01-09, version 3.2.16*

gpsログを記録中他のアプリや電源を入れてない状態だと高確率で中断されますが
設定の計測間隔を距離じゃなくて時間にしたら
中断されなくなりました。参考にどうぞ

### 3/5 — 最近GPS信号ロストが頻発

*2021-07-28, version 3.2.15*

もう10年くらい愛用し、雑誌などの取材時にも行動記録として役立てていますが、最近計測中にGPSをロストして正確に計測できない症状が頻発しています。全くできないわけでなく、戻ってくることもあり。

iPhone8plusが古くなったせいかとも思いましたが、12proに変更しても変わらず。OSの問題かもしれません。ただいま14.7。

### 1/5 — Unusable

*2021-04-21*

The app is free to download but no features can be used without a subscription. 

This isn’t clear in the app description. 

Rather pointless.

### 4/5 — 自動ＯＮ.ＯＦＦ機能

*2021-03-09, version 3.2.14*

便利に使わせていただいております。

自動で指定した日時に計測のオン・オフ機能をつけられないでしょうか。日々の行動記録を自動でとりたいのでよろしくお願いします。
