I took an iPhone Timelapse of my recent one hour flight but it ended up being so fast you could not see the details! So I got this app after the first app, and it let me do exactly what I wanted! Slow down parts of my video a little, and a lot in other parts! (Take off and landing slowest, flying a little faster) This app is great! And I really love the fact that this is made by two people who want to make something super helpful for people to use for free. Those are my honest thoughts on this app and I hope this helps. ### 5/5 — Still My Go-To SloMo App *2024-07-15, version 2.5* It’s simple, easy to navigate, does the job perfectly every time, and reduces storage use of each video. It’s free, and has zero ads. Simply perfect for slowing down or speeding up videos. ### 5/5 — 非常推薦 *2024-01-11, version 2.5* 好好用呀👍👍易用簡單，可以局部地調快慢。Very easy to use. You can partially edit slow and fast as you like. ### 5/5 — Worked great before, but now crashing *2023-02-05, version 2.5* Tried multiple clips… crashes when I click export every time. ### 5/5 — App top demais *2022-10-22, version 2.5* Parabéns aos desenvolvedores! Top App ### 5/5 — Thanks *2022-09-11, version 2.5* Thanks it’s free and easy to use ### 5/5 — Slow Fast *2022-05-24, version 2.5* Osm ### 5/5 — Supports portrait too! *2022-02-06, version 2.5* Works incredibly well and I’m happy to find a solid, free app that lets me fine tune my slow motion videos. The waveform approach is intuitive, adding and removing points works well, and the best bit - it preserves original resolution meaning my portrait slo-no vids can go into Adobe Rush! Very pleased with the Neat app 😄 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
