I don't know if you are aware of it, but the battery in your electronic devices, if it is charged to 100% every time, gradually loses its efficiency, so your health suffers the consequences.
But my app helps you, in fact it allows you to set your own charging percentage (80% recommended); so that when this threshold is reached, a convenient reminder is indicated. But the nice thing is that if you don't remove your device from the power, the warning will remain continuous... this is because my app cares about the health of the things that are most precious to you.
