Amazing

This app is a great demonstrator for gravitational lensing

Needs an update for ios 11

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.

Excellent app

Does exactly what it says. Yes, it is somewhat like some Photoshop effects, but this is real physics. And cool physics at that!
