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.



  • Just include a set of instructions please

    I am 70 years old and have very little technology knowhow. Please just include (in your app) a set of instructions on how to use it. Maybe put a "help" button. Duh? step 1, step 2, step 3, etc. It's just that easy. I wouldn't think this app is just for young people, is it?
  • Very good. Needs a way to fine tune points.

    Great, straight-to-the-point app for editing the speed of multiple parts of a slow-mo video. The problem is the lack of fine tuning. Needs a method for zooming in on the editing timeline to tweak the exact edit points.
  • Does what it says, no tricks.

    I’m not an actor or a shill for these guys, just happy to find an app to speed up my video!
  • Amazing!

    ABSOLUTELY amazing app. 10/10. This doesn’t give you any ads, no problems, quality, any thing you could ask for. I have a idea that can improve this app. My idea that I’ve always wanted to see was a speed editor where you can select a place where you want the speed to go. For example, One Half of the screen is Slow While the other would be fast, or The Vibrating Hand move from Cw’s the Flash! This would make the app 1000 times better than it already is! Other than that, Outstanding app.

    I needed this for a school project and it helped ALOT; I especially liked the fact that there weren’t any in-app purchases for extra features
  • lit lol

    I never write reviews for apps but i had to for this one. This is the best app if you wanna make a velocity edit. I use video star to make edits but you have to pay for an extra feature to make a velocity edit. Im so glad i found this app and it lets me control the speed wherever i want it to be.
  • Change something please

    By FrozenMusic101
    The app is really cool, but if you can change the fact that if you wanted to have a song in the slow mo, the slo mo wouldn’t change the song to a slow mo as well.
  • Amazing BUT..

    By 😜😍😎😜
    This app is amazing! There are so many different ways to use this app and put it to use. I learned how to use it pretty fast but I have one question! How do you add more of the dots? I can’t figure it out! I can only get faded ones to show up that disappear once I tap my screen again
  • Laggy
