I just recently got this app, and I quite like it. I can film any video using the app and it allows it to play backwards. I can then save the video to my camera app and use it any way I want! I think that everything is perfect... but there are a lot of ads.
LUCKILY, the ads usually play while the backwards video is loading, so they really do no harm.
One thing I was a little worried about was when I saved the videos, I realized that the screen was squared. The visual size of the screen was different than normal videos. (The black bars on the sides are a lot bigger than usual). This looks pretty strange if I play the backwards video in a slideshow, or beside normal videos. That can have a pretty big impact on projects depending on what they are. (In my case, it does).
Another problem is that there is a time limit for the videos. You can only make videos under one minute. If it reaches a minute, you can not use that video...😕 That was a little but disappointing. But very easy to work around.
Unfortunately, those are the two things that lowered my rating. Otherwise I, I would have given it five stars...
I also just got this app, so I'll probably find more things to like about it. (I wonder if it will let me LOAD videos...)
But either way, I really recommend this app! You can really create beautiful videos with it. It's really fun to use and once you make one video, you can never stop!!
