Self Timer Cam & Teleprompter

If you just want to take a few selfies then its usable. However I needed to take pictures every minute or two for a day of the display on a smart thermostat to identify a problem with my heating system. The App took hundreds of pictures under my instructions. I then found out what was not disclosed: 1) The pictures do not have a time stamp. 2) I could not select All pictures to save them to the photo library with just one command, but only one at a time. The time stamp in the photo library is set to the time the picture was saved there - useless. 3) The pictures in the App’s own library are displayed 3 across making it awkward to inspect them quickly. You can tap on a picture to see it full screen, but you have to go back to the 3 across state to look at the next picture. I don’t understand why the App can be programmed to take unlimited pictures without giving you basic tools to manage a large number of them. I assumed that was what I paid for. What was the developer thinking?
