Photogene by Omer Shoor
Photogene is one of the first iPad photo editing apps and still stands the test of time, despite that it's last update was issued in September of 2014. Photogene provides all the basic tools for editing photos like cropping, retouching, and enhancements. The app also comes with the ability to add text and an array of export options. One of the latest updates included the ability to combine photos into collages. Photogene is $2.99. I hope the developer considers future updates.
