User Reviews

This app is a great demonstrator for gravitational lensing

by Jo*****, 2020-02-03

This is a fantastic app when it works - but it doesn't save your edits reliably. It keeps saving the unedited source. update: 11/18: iOS 12.1 on a new iPhone X - still isn't working properly. It allows you to manipulate the image to your heart's content, but will not save anything but the source image. Very disappointing. Used to be a great app.
