This free flashlight app is designed to work on Android smartphones. The app will let you set a custom alert for each notification, so you will know which one is for your phone. You can choose to have it blink on every notification, or just for the ones from your favorite apps. It can also be set to work with your phone's default notification settings.

It has a built-in flashlight, and you can use it to light up your way in a dark place. It's also great for use in outdoor activities, or when you're using a headset.

This app is simple to use, and you don't need any special skills to use it.
