### 2/5 — 飛行機での使用レビュー

*2026-08-31*

加速するプロセスは問題なく計測された。
スマホをオフにすると記録は取れない。
飛行中にこのアプリを起動しても計測しない。スローなところから計測しないといけない。

**Developer response:** 詳しいレビューをありがとうございます。飛行機で使っていただけたこと、とてもうれしいです

レビューを拝読して、バージョン1.2.0で次の変更を行いました
・GPSを探している間や信号が途切れたときに、状態を画面に表示するようにしました。飛行機モードで起動した場合、衛星を捕捉するまで数分かかることがありますが、GPSを掴めていない間は「GPSを探しています」と表示されるようにいたしました
・合わせて、歩行時の速度表示を安定させ、ゆっくり歩いたときの距離の計算も修正しました

画面をロックすると計測が止まる件は、まだ対応できていません
バックグラウンドでの計測は今後の改善候補として検討しています

貴重なフィードバックをいただき、ありがとうございました
