Simple and fun little app!

Great app I made a video of my travels whilst away on my gap year. I would say it’s slightly annoying that you have to add the music every time you go into the app also it can’t crop stuff to portrait size for you so I got a second app called video crop so that I could crop some go pro videos to portrait size so that I could fit it into the app without it looking weird. After playing around with percentages I managed to fit each clip perfectly and the video produced was great! Last thing is that sometimes it said it was loading clip but when I exited it after waiting ages it was there already! I exited it every time it had the loading box and was fine but perhaps a glitch that they need to fix with the app!

I love it! (but...)

This is without a doubt my favourite app! I take so much pride in showing people my video of the days.
However for some reason, on the 8th August, I always try to add my Live Photo in which usually works as the majority of my nearly 300 videos are from Live Photos. But it doesn’t work! I’ve got 2 photos from that day and neither work. My sister has the same problem on her phone with the 8th August! It must be some issue with that particular day. So I’m wondering if this can possibly be fixed?
But thank you for creating such a fab app, I recommend to all!

Love it

I had this app about a year ago but deleted it because all the videos were being saved to my camera roll and I found it very annoying but I was looking through all the apps I used to have and thought I’d give it another try and found that you could change that so they are stored on the app. I now love it- it’s so artsy and such a laugh. I love watching back- so cute. I would recommend this to anyone!!!!
