Great app except for the fact that you have to do everything in one sitting. If you have multiple videos to do you can't close this app and come back to it because once you do, it crashes. So what you have to do whenever you want to use it is uninstall it and then reinstall it. It's a hassle. I hope they'll update this.

Very frustrating

Would put a -5 stars if I could... I thought this app would be like an old one that I had on my old phone called "tempo", which was very easy, simple, and straight forward to use. This will not let me adjust the speed as I intend, will change things that I had already set, is overall very frustrating to use, and plays wayyyyyy wayyyy wayyyy wayyyyy wayyyy too many ads.
The app keeps closing on me too. Extra frustrating because the idea is great, just very poorly done...

Helpful but...

I love this to make videos but whenever I exit out of the app I can never get back in. I have to delete and reinstall the app everytime. If it didn't do that then I live it!!
