iPhone 7を使っているのですが、ログファイルを開けません。iPad では開けるので、わざわざiPad を使ってみてます。iPhone でも開けるようにして欲しいです。

### 5/5 — Very useful and simple App!

*2022-07-18*

Good app, easy to use with just what is really useful to display. Arigato gozaimasu

### 3/5 — OK viewer, poor flight mode

*2020-04-26*

I thought this would be a great app to use for soaring. Unfortunately there is no way to upload a task. Each point must be entered. You should be able to upload a .cup file for a flight task to fly.

### 4/5 — ログファイルが開けない（開けるようになりました）

*2019-06-13*

iPad mini4を使ってますが、igcファイルを開こうとするとアプリが終了してしまいます。解決策はあるんでしょうか。良さそうなアプリなだけに残念です。

アップデートされてファイルを開けるようになりました。対応ありがとうございました。
次合宿からは記録ができるか試してみます。
