Icon8 is a photo editor with which you can customize your selfies with various filters to give a unique touch and amaze your friends.
While the app is optimized for selfies it also lets you apply filters to any other picture, in addition to directly sharing your selfies on Instagram and other apps.
When you open the app it lets you choose between your frontal or rear camera to take the photo and then apply filters. You can also search for photos from your device's memory for editing.
