Works Fine - Maybe

This program works fine *IF* you work it *exactly* as it expects...the correct steps for which are undocumented.
1) If you set up a time lapse and decide to stop taking images in the middle, you can not create a time lapse, nor do you have a way of seeing or deleting the thousands of images already taken. (You can recover the memory iLapse used for those images by deleting the iLapse app, turning your iPad off and on again, and then reloading iLapse from the iTunes Store.)
1) if you interrupt taking photos for a manual time lapse, you can create it. But if you inadvertently press the "wrong" buttons, the software will happily and simultaneously move those thousands of images to your photo album and try to create another time lapse. It will not be successful. And there is no way to send those thousands of images back to the iLapse app from your photo album.
Both of these HCI issues indicate a slap-dash, untested app, and thats simply unprofessional.
