DPI Convert

DPI Convert was developed by one lazy Android developer to other lazy-bones, which doesn’t want to convert all dimensions of graphic resources for screens with different dot density in the mind.
And now we’ve got a great app for this task. It’s really simple in use and extremely aggective in its work. If you need to convert dimensions for:
xxhdpi (~480dpi)
xhdpi (~320dpi)
hdpi (~240dpi)
mdpi (~160dpi)
tvdpi (~213dpi)
ldpi (~120dpi)
then DPI Convert will do it for you with pleasure! So if you think that you need something like this, then just download it. Besides this DPI calculator is free )

PS. Don’t forget to write comments, wishes and so on.
