Tell your friends about your new solar charger app. Impress them. Expose your phone screen to sunlight to see how fast it charges.
A virtual ampermeter will show you how much current you get.
Don't get fooled! Unless you use a real charger, the phone won't charge even for a bit. Of course it's a prank but your friends don't know it yet.
