Cant save the pic

Wanted an app that allows a longer exposure for astronomy pics with iPhone. This app wont save the pics. Just a blank white screen. You can take a screen shot and edit out all the ads and junk but field of view is really small. I thought all the bad reviews were mostly people not using app right. Nope. Ive tried many different ways to get an image saved and no luck. Cant recommend this app at all.
