Slow Fast Slow - Control the Speed of Your Videos App Reviews

Amazing app! Love the simplicity of the controls and the smoothness of the slo mo! If you do editing, this is the app for you!! And I love that there arent any advertisements

Exactly what I was looking for. Allows you to slow your video AND keep it at the same pitch; great for musicians. Thanks!

It did an amazing job with my video and I got the exact results that I was looking for!!!

Ive used this app briefly but from what Ive seen it is absolutely incredible. 240fps to 480fps AND backwards rendering for an iPhone 6/6 Plus and FREE....WOW!!!!!!

Thank you for making such an amazing app for free, you guys are awesome keep it up!

I cannot save the video to camera roll. Its all black. I cannot use. Please fix it.

Its just a waste of money with these properties. It needs to be improved. There must be more video formats like 16:9, 4:3 Also there must be an import option to edit previous videos that we shot.

Problem to save in portrait orientation

Everything is absolutely great after last update;)

This app really awesome!:)

Best slow mo app ever! gj guys

Bad resolution even on iPhone 5S , cant import from camera roll, square movies and low resolution ! With all these premises you cant really use this app!

Ive been looking for an app like this since I first got my iPhone three years ago. It slows down or speeds up a video with fade in or fade out effects, that is the video slowly slows down or slowly speeds up. Just set the cue in and cue out points. Its simple and intuitive and it works just fine. And its free! Can you believe it?

This app was my saving grace! I tried another app like this and it was a disaster. I couldnt get it todo what it was supposed to, the sound cut out halfway through, it took ages to load and had a huge watermark. After that experience, this app is a dream! Its so easy to use. It makes sense and works quickly. The video I created looked exactly how I wanted it to! 10/10

I love this app! Works amazing!

This is the only app that I found that you dont have to pay extra for anything, and dont have to upgrade to a new version, or PUTS WATERMARK ON YOU VIDEOS. Its AMAZING and so easy to use!

Perfect app for adjusting clip speeds at multiple intervals

I searched for an app like this for quite a while and I finally found it! Thank you so much. Nice, simple and very useful.

This app is exactly what i have been looking for to add effects to my videos :D would recommend, perfect app

This app is just what I was looking for. Easy to use and beautiful interface. Works flawlessly on the iPhone 6 plus.
