Một ứng dụng Đồng hồ bấm giờ đơn giản

If you're running or on a bike at night and need something to make it safer, this app might help. You can enable it to blink every few seconds in red/white. Keep the phone in your hand or attach it where visible.

It can run in the background so you can play music. It also keeps a local history of your activities.
