The developers have abandoned it, and they stripped it of all it's best features before they did. ### 3/5 — Used to be good, devs seem dormant *2026-08-05, version 3.8.1* This app used to be great but now I can’t even select some of the render options and it won’t save my output video to my photos app or files app. Really disappointed, this used to be better than the built in slow motion tool in iOS but now it’s a bit clunky and non-functional. 3 stars as it has potential if bugs are resolved! ### 5/5 — The best… *2026-06-20, version 3.8.1* SloPro is by far the best slow motion app out there that I’ve seen or used. Not only that if you don’t mind a small watermark at the bottom of the screen you don’t have to pay a penny for it. I paid for premium that removed the water mark voluntarily, after years of using the app. My one criticism would be when late last year I upgraded to iPhone 17 I had 31 gb of stored data on the app but I couldn’t use the app anymore because according to the App Store the app wasn’t available in the UK anymore. I was heartbroken but I didn’t delete the data from the app for months just in case it was available again in the uk. 3 months in I needed the memory so after trying and trying to redownload it for months I deleted the app 2 months later after trying multiple different slow motion apps (ALL paid weekly or monthly ALL useless) I randomly tried it again & got it back!! Unfortunately I had deleted all the 31 gb of my data but at least I have the opportunity to start again with the best Slow Motion app out there!! Thank you developer please make sure we get to use it in the uk indefinitely. Thank you ### 5/5 — :) *2026-05-24, version 3.8.1* Yeessss!!! It’s finally back!!🤩🤩 ### 4/5 — Good quality *2025-03-18, version 3.8.1* Great slow motion very smooth, just on the free version is great quality it what I use for any sports, cars races, motocross, it’s the best free app I’ve found! ### 5/5 — Please update 🙏🏻 *2025-03-14, version 3.8.1* this app was ahead of its time since it came out and now it’s 4 years old. Please give us an update ### 5/5 — Love it *2025-01-21, version 3.8.1* Works great no complaints here ### 1/5 — Broken *2025-01-13, version 3.8.1* The free version doesn’t allow for any settings to change on my iPhone 16. And when I tried to buy the Pro version, the “Buy” button didn’t work. Why is this still even in the App Store… ### 3/5 — 🤷🏽‍♀️ *2025-01-10, version 3.8.1* I’ve used this app before to edit some videos and recently decided to start back editing, it’s a great app but I’ve encountered one issue which is the fact that i’m no longer able to save the slowed videos to my gallery and i have bo clue as to why that’s happening. ### 1/5 — Version PRO *2024-12-25, version 3.8.1* I bought a PRO version but when I changed my iPhone can’t restore the purchased PRO version ## Frequently asked questions about SloPro ### What does SloPro do?
