Also won’t recognize iPhone 17 in settings. Help **Developer response:** Thank you for pointing this out. Hotfix is on the way! ### 2/5 — doesn’t work well! *2025-10-31* unfortunately all that the 4k option did was add a light filter.. no quality was adjusted! **Developer response:** Thank you for your feedback. We recommend trying version 3.2, which features an improved algorithm and upgraded ML models for better performance. Your input is valuable, and we encourage you to use the in-app support for further assistance. ### 1/5 — No change whatsoever. *2025-04-06* I have now attempted to upscale some 31 videos. Not one has a perceptible change to the quality in any way. I have attempted HD, 4K, 8K, and 16K, although every attempt scale to 16K has met with an error “not enough pixel information.” It is clear that this app does not work. I have cancels the subscription and will be demanding a refund from the Apple Store. Edit: developer responded to another negative review by claiming the app does not “upscale”. Which is odd because it’s literally in the app description. Further, all support is in Russian. Do NOT BUY! ### 2/5 — . *2025-03-24, version 2.9* I need to uninstall the application everytime i want to upscale a video? Why does it do this😒 ### 1/5 — Fake *2025-02-25* I want my monthly subscription money back .. doesn do anything ### 3/5 — Paid for Subscription not working *2025-02-13, version 2.9* Hello, I paid money for the subscription in which I still have available through my apple subscriptions. However it isn’t saying I have not got a subscription and have to pay to upscale my videos. Please can you fix this. Thank you ### 1/5 — Scam!! Doesn’t work! *2024-12-05, version 2.8* The app is a scam that takes your money and doesn’t upscale videos. ### 3/5 — Not sure yet *2024-10-27, version 2.6* Is there a way to get a preview of the results like a test run before paying a whole months subscription? I can’t see what I’m paying for and there is mixed reviews on here if it works or not, thanks. ### 1/5 — Обман *2024-10-26, version 2.6* Оно абсолютно никак не меняет качество видео ### 1/5 — Don’t install this app *2024-10-18, version 2.6* I am a YouTube content creator I installed this application to enhance my video quality I select 4K resolution to my video after saving to my photo library. They completely compromise my original video quality, the other watermark prevent YouTube to viral or except. The application are the water marked your video when you upload this video to YouTube or another social media app platform the curler does not accept. Your social media platform does not accept your edited video. ### 1/5 — Doesn’t work *2024-07-29* Doesn’t work or upload videos **Developer response:** There is no uploading feature. Confused with another app? ### 1/5 — A complete scam *2024-07-24* Not able to upscale videos **Developer response:** If you open video before and after in 100% zoom - you will see the difference. It does upscale videos but just don't expect magic from a mobile device. ### 1/5 — Лохотрон *2024-07-04, version 2.3* Верните деньги! ### 1/5 — SAVES YOUR VIDEOS! *2024-06-04* This app saves your videos!! I deleted a video of mine twice but it kept showing up when I tried adding a new video. May not be safe!! And oh be quiet how come i completely deleted it but it still shows up? I don’t want to hear it **Developer response:** It’s wrong, app doesn’t keep user videos. ### 2/5 — Better… *2024-05-29* The black covering the whole other side of the video is fixed, but it still outputs it in the same quality as before. And it won’t let you change the video you first converted. I also don’t really like that the audio of the video plays at the same time in different points in it. **Developer response:** It’s fixed, try updated version. ## Most critical reviews (10 lowest-rated) ### 1/5 — Free version *2026-05-29* Worked good for a day then stopped, it’ll upscale but won’t save. **Developer response:** Free usage ran out. ### 1/5 — Not sure what’s going on.. *2026-02-19* Tried to contact through app support and haven’t received any help.

I tried reloading the app, attempting different videos but nothing worked. Either way it didn’t work for me. ### 1/5 — Won’t switch videos *2025-05-15* It allows you to upscale 1 video, despite paying for the subscription ### 1/5 — Do not pay for premium *2025-05-12* This app is garbage ### 1/5 — Grosse arnaque ne vaut rien !! A fuir !!! *2025-05-11, version 2.9* Passez votre chemin cette app est une arnaque elle ne fait rien de bien. C’est inadmissible une app de si mauvaise qualité dans l’AppStore ! C’est indigne d’Apple et ainsi que le refus de rembourser les 8,99Euro d’abonnement que j’ai pris pour espérer que la conversion de la vidéo soit de meilleure qualité mais non rien. On a bien meilleur résultat avec l’application photo ! Je recommande de boycotter cette arnaque. ### 1/5 — Rubbish *2025-04-24, version 2.9* Doesn’t do anything but increase file size ## Most praised reviews (10 highest-rated) ### 5/5 — I love *2026-03-01* The best 👍🏻😍 **Developer response:** Thank you so much! ### 5/5 — Функции. *2025-03-22, version 2.9* Не знаю у кого как, но у меня лично все работает на ура)) ### 5/5 — This app does NOT a work!! You charged me $7.99 for something that doesn’t work! *2024-09-01* IIi **Developer response:** Please reach out to s@kovallux.com, describe your problem and I will try to help. ### 5/5 — Nice job ! *2023-09-12, version 1.9.1* Beta pls ### 5/5 — Thank you so much! *2023-02-13, version 1.8.3* This app saved me so much time and assume that I thought I was going to have to through! You deserve this 5 star rating and I hope you continue to strive with this app! ### 5/5 — worked perfectly *2022-09-21* i'm actually shocked by the amount of negative reviews for this app. i saw taylor swift last night and was so disappointed when i realized i recorded all my videos in 1080p instead of 4k. i used this to convert them and can definitely tell a difference in the clarity and quality, and i had no issues saving the converted vids. i never write reviews but i was disappointed to see so many negative ones when my experience has been so positive. thank u for fixing my tswift vids :-) **Developer response:** Thank you so much! Reviews like this inspire me to continue development of this app. Negative reviews are given by competitors on purpose. ### 5/5 — Ok it’s fixed to landscape so 5 stars *2021-06-16, version 1.5* Ok fixed now so it’s perfect ty ### 4/5 — Great app, has two bugs that should be fixed. *2025-03-30* Running the latest IOS on an IPhone 15pro max. The two issues I keep getting are that even if you select a video, a previous converted video shows up in the window, and the other issue is when you hit the + button or select a video to convert, the video browser just gives you the entire video folder. It should lead to the menu that shows your separate folders. Especially if I move 20 videos from all over my library into one new folder… I’d like to be able to access that new folder to pull videos instead of navigating through my entire video folder which has thousands of videos. Other than those two big issues, the app does exactly what it says it does. Wonderful upscaling. **Developer response:** Thanks a lot for your review! The first bug I will fix, the second is tricky, I will see what can be done. ### 4/5 — Really good! *2024-10-09, version 2.6* This app is rlly good, althought somtimes it lags and the I can’t change the video ### 4/5 — Nice app *2022-07-15, version 1.8.1* Nice app --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
