iPhone Screenshots


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.

Please update to iOS 13

I wish the developer still have time and energy to update the app. The simplest and coolest app to control speed. Unfortunately have not been updated for a while. No longer full screen on some iPhone and also it does not recognize video on iCloud.

The best.

Really straightforward and easy to use. Did exactly what I need it to the very first time.
Love the little intro sharing the guys’ shop, makes it seem really personal and human.
No adds or pop ups.
