ChargeTone is a useful Android application developed by Tal Aviram that solves the problem of not knowing if your device is charging or not. This app provides comprehensive control over charge state notifications, ensuring that you never miss an important charging event again.

With ChargeTone, you can receive audible tones or vibrations when your device is connected or disconnected from a charger or computer. This is especially useful for devices that do not provide built-in notifications for charging or discharging. Additionally, you can set a specific target percentage to be notified when your battery reaches that level.

For those who want more advanced features, ChargeTone offers premium upgradable options. These include the removal of ads and the ability to choose your own customized notification sounds.

Please note that ChargeTone requires certain permissions, such as internet access for ads, and billing access for unlocking premium features. If you encounter any issues with the app, it may be due to aggressive app-killing settings on some phone manufacturers' devices.

Overall, ChargeTone is a reliable and convenient solution for staying informed about your device's charging status. If you're tired of waking up to an uncharged phone, give ChargeTone a try.
