I just published my first Android app "Check charge", Check charge is free of charge app which indicates the battery charge level of your device.Check charge is a small, sleek and elegant app that will help you to follow the current battery percentage and temperature of the battery on your device.When Mobile Charger is Connected, Check charge screen will be appeared automatically with the Battery and Temperature details. thanks!

Here is the app: https://play.google.com/store/apps/details?id=com.usbplugged
