Never forget to charge your phone again

Battery Alert is a simple app that plays a sound when your battery gets low. The sound keeps playing until you plug in your charger, even if you've closed the app.

That's it. No complicated settings, no accounts, no internet needed. Just install it, pick a battery level, and you're done.

Simple and lightweight

No ads. No sign-up. No internet needed. The app keeps running quietly in the background, even after you close it, and uses almost no battery. When your battery gets low, it plays a sound to remind you to charge.

How it works
1

Install the app

Download and open it. No account needed, nothing to set up.

2

Choose your battery level

Use the slider to pick when you want to be reminded. For example, 20% means the sound plays when your battery reaches 20%.

3

You hear a sound

When your battery gets low, the app plays an alarm sound so you know it's time to charge. This works whether the app is open or not.

4

Plug in your charger

The sound stops automatically when you connect the charger. That's all you need to do.

Easy to use

Built for everyone

Large buttons, big text, and high contrast colors. Easy to read and use, even without your glasses. Works great with screen readers.

Always watching

Works in the background

Starts automatically after your phone reboots. A small status bar icon lets you see at a glance that monitoring is active. Uses almost no battery.

Your privacy

Nothing leaves your phone

No data is collected. No internet connection used. Everything stays on your phone. We can't see anything, and we don't want to.
