Video Speed Editor Slow & Fast 4+

I actually liked this app more than I thought I would. I came in looking to make a video faster and I saw that I could ALSO make it slower. The only thing I didn't like was that the app wanted me to pay to make the video a little more faster or slower. I think there needs to be more if I'm going to buy it. Not exciting enough...

I understand that paying for goods and services is logical and when I went to use the 8x speed it charged me for premium but then I couldn’t use the 4x speed without premium either so I can only use 2x speed to make my video faster which isn’t a lot and this wouldn’t be so bad if a 20 minute video was able to be sped up but your paying to put 8x speed on a 10 minute video at max when it would be very useful on a 20 minute video. The trimming is horrible too! You can only trim from the beginning of your video to any part of the video but the beginning of the video can’t be trimmed of! Also you HAVE to trim it if you want to change the speed so you have to have a small useless part of the video to trim off to use this! Don’t use this app if you want to actually speed up or slow down your video without any problems constantly popping up. Thank you.

App crashes now every time I try to open it. When I check to see what’s running on my phone, it still shows this App, but when I select it, it crashes again! When I close it completely and try to run it again, it still crashes. My iPhone7 is still on iOS 13.??, so it can’t be the new 14.?? iOS causing this video app to crash. Funny but it use to run when I first got this stupid App. I am now uninstalling it and would not recommend it! BTW, iMove is free with your Apple phone and let’s you speed up or slow down sections of your video for FREE!!!!

Update: I uninstalled it then reinstalled it and it no longer crashes, BUT now when I try to change speed of video, a message pops up asking for $2.99 to make the change? Forget that crap. Lke I said before, iMovie does a better job for free and comes with your iPhone!
