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

I accidentally shot some videos in slow motion and with app I was able to view the video at regular speed as it was meant to be. Great job and thanks.

Finally found the app I was looking for! Easy to use and has the exact slow motion/speed up features I was looking for.... Definitely recommend this app!

i really like the way this app works and the idea of it but ive been having trouble saving the videos please tell me how i can fix this

You can actually adjust the speed of each part of your video.

It is totally awesome. Good work!

Ive been looking for an app for a looooong time. But now, Im not. I would recommend this amazing app.

It is able to speed up videos much faster than other editors and doesnt even have a watermark!

After scouring the App Store for an app like this, I found many which claimed to slow video down, but were not even able to deal with the video I needed to edit. This one was not only able to edit it, but also kept the correct pitch after the fact. Kudos to the devs!

I havent actually uesed it yet but my friend likes it a lot so u know its cool jkjk its amazing

Fantastic app

This seems to be the only app in the App Store that can speed up or slow down your videos well, and also free of charge. Yay!

I looked through a lot of slo- motion apps before finding this one and it was definitely was worth the searching. This app worked so well and I made some awesome videos. This is definitely the best free slo-mo app ever made.

I wanted to speed up a video and this app did the job with fine speed ramping control. Solid simple app that works.

thankyouverymuch! ran into the whole exporting/syncing issue with slow-mo films and this app does exactly what i needed, free to boot! great to learn it’s a promo from the slick glif folks (bought original one on kickstarter = iphone 6s is jealous of the new design). only advice i can offer is to give a subtle gray line to help guide us at which % changes we need to turn 240fps footage to 30fps = 12.5%. had to do a quick calculation to learn that. also useful if i could drag the line = keeping points as they are but moving together.

Thor app is the best one I found! It has so much control over the speed, it doesnt crop the video or cut it!

When I finish editing a video and press the save button, it tells me that it successfully exported the video into my photo library but when I go into my library, the video is not there. If someone know the solution to this problem, please let me know.

After several uses, the app size increases to over 500MB. Its a challenge to my 16GB phone. What a pity but have to delete this very app.

So thankful they offer it for free, makes me want to buy what they actually do sell for sustenance

Got it for kicks, kept it forever. It actually got me into making and editing videos!

I time lapse my drawing videos to share and needed a quick way to super speed them up without having to open far larger applications. This is as near perfect to simplicity as it can get. The only addition I would suggest would be a way to see the actual time on the videos just to see how much time I have shaved off. I have tried all those other free apps and they royally sucked at something as simple as to just slow or speed up videos without sacrificing the quality. Thank you for this fabulous app.
