Camera Timer!

I also had the problem of thinking I was taking multiple shot to later realize that only one was saved. The solution that I found was to turn off cellular and wifi data. This prevents the advertisements from starting. The ads seem to interfere with storing the pics. Hope this helps someone. Otherwise it works as expected.

I wish I had found this free app before I spent money on a few other paid apps that couldn't deliver this simple feature: taking multiple photos at a set interval. The max number of photos you can set up for his app is 30, which is a lot higher than another paid app that allows only 10!!

I loved this app before the last two updates. Now it put the phone to sleep missing 90% of the photos I want it to capture. I use this for my business so it's frustrating that I waste a ton of time turning the phone back on.
