One of the most interesting features in Overlay is that it lets you add text to any photo. You can choose what you want to write, the font, color, position, angle, and opacity. Basically, you have total freedom.
Other features of Overlay let you add filters as well as make basic corrections by adjusting brightness, saturation, contrast, and so on. Once you finish working with your photo, of course, you can save it to your memory or share it directly.
Overlay is a great photo editing app that presents a wide range of features in an elegant and easy-to-use interface. It's a very interesting alternative among the many image editing tools available on Android.
