最近のアップデートまでは特に不具合もなく快適に使用していたが、ここ数ヶ月ほどのアップデート以後、HIITの2回目でクラッシュからの強制終了する確率がとても増えたのと、クラッシュからの復帰後にジャンプ感度が低下することが増えた。それとは別に高頻度でApple Watchからの心拍数を読み込めない事が増えた。運動アプリとして致命的なバグだと思う。
1. If your watch is Apple Watch SE or Series 5, there have been reports of occasional crashes with this model. You can temporarily resolve this issue by turning off "Voice Tip" in the watch app or selecting "iPhone Only" under "Voice Tip - Output Device".2. The app simply displays data provided by the system. Apple Watch is quite accurate in measuring resting heart rate but may occasionally fail to track or provide accurate readings during intense physical activities . This issue is related to hardware and not the app, and it is more likely to occur in winter.
