Difficult to get running

Unfortunately this app isnt saving video to my photo collection. I purchased it last night and this morning it indicated 14 videos had been captured. But none apparently saved to the photo album or otherwise preserved for viewing. This is on my old 4s...
*update*
After several deletes hard resets and reinstalls, the program seems to be working.
