Slow Fast Slow is an app for manipulating the speed of videos you shoot on your iPhone. It works especially well with slo-mo videos. Use the intuitive interactive timeline to slow down or speed up your videos. Additionally, you can add pitch control, as well as clip reversal. • Import videos from your Photo Library. • 240 fps videos (iPhone 6 and 6 Plus) can be slowed down to 1/16 speed, which is twice as slow as the built in camera app. • Pitch Control: Retain the correct audio pitch even when the video is sped up or slowed down. • Backwards playback. • Add and remove points to adjust the timeline. • Export videos in the original ratio or square. • Requires iOS 10.



  • This app is great!

    I mistakenly recorded video in slo-mo on my IPhone X camera. This app easily converted it to normal. Thank you!
  • So convenient!

    I love that you can add and remove points! A lot of other apps don’t have this option but thank god this app does! If you’re not happy with your edit you can still go back and fix it!
  • Solid, straightforward app

    By SoundShop
    This app is extremely simple to use and effective at what it does—slow/fast video with easy ramp up/down functionality. The only thing I can think of to make it better would be to make the ramp up/down transitions smoother. Besides that it’s perfect.
  • Great app

  • 5 Star App that crashes

    By Live2bProof
    This is by far the BEST free slow motion to fast motion app out there. The customization you get with being able to adjust specific, different parts of the video is really nice. It’s easy to use. Also, you can reverse your video if needed. A lot of great features for sure! The only annoying this is that the app now crashes on me whenever it goes to compress my videos. It didn’t do it originally but within recent uses, it now crashes every time it tries to compress and save the video. CREATOR, PLEASE FIX THIS!!!

    It’s works great! At first I was only confused because I didn’t read “fast & slow”. If you are a YouTuber &/or want to edit certain parts of your videos this is the app for you!
  • Video Won’t show up

    It sounds great and all, but I downloaded this app and went to use it. So far so good, right? I went to add the video and tapped on my video. It wouldn’t show up and I tried multiple times. It was free and there was no added purchases, but that’s about it
