True Amps

True Amps is a customization app that lets you change what you see on your lock screen while you're phone is charging. With this app, you'll see a circle on the screen that indicates how much of the battery is left to charge and how long it'll be until the battery is completely charged.

The great thing about True Amps is that it offers tons of customization options. You can change the main color of the circles, choosing between several different colors, and even adjust the intensity levels of each one. Plus, you can also customize the amount of information that's shown on the screen while the device is charging, change the background color to black or white, choose what sound you want to hear when you should charge your phone and when it's fully charged, etc.

This app is incredibly simple and intuitive to use. You just have to give it permission to run on top of other apps, in the settings, and start tinkering with the different features until you create the configuration that best suits your needs.

True Amps is a good customization app that's perfect if you're looking to give your smartphone an extra special look while it's charging.
