Pensez à le rendre possible en limitant par exemple la quantité : 1 par semaine/ou au pire 1 par mois Ça serait top et donnerait envie de passer au payant si 8x efficace Sinon bravo 👏👏👏👏👏👏 ### 3/5 — Photo upscale *2025-12-04, version 3.2* Does work, n quite simple needs polishing, Changes face structure, Weak edit in this Ai era, ### 5/5 — Just wow *2025-12-03, version 3.2* Right when I thought there was no app without it being greedy. Here was this app to save the day ### 5/5 — 1 Most User Friendly *2025-11-28, version 3.2* I love how easy and excellent Upscale is, as an Artist and designer this is a must for my end product ### 5/5 — Love it *2025-11-18* Love love so effortless ### 4/5 — Kg *2025-10-17, version 3.2* Good app ### 5/5 — Kind of amazing !! *2025-10-16, version 3.2* I restored a picture of a statue, and frankly it was quite incredible ! Detail I could not have imagined .. Highly recommend! ### 2/5 — Good but messes up background *2025-09-23, version 3.2* Yes, it genuinly does do what u want it to do, it gets rid of every little piece of noise and grain, but it makes like the black outlines boxes in the background, if they weren’t there it would’ve been goated. ### 5/5 — Exactly what i was looking for *2025-09-18, version 3.2* So happy it’s a one time purchase and not subscription slop! Works just as well as a similar program I use on desktop and surprisingly fast. My only critique is there should be more details on what button does what exactly. Thank you🙏 ## Most critical reviews (10 lowest-rated) ### 1/5 — There is no free use *2026-02-27* You cannot use the simple feature without taking the « pro » version of the application, so you don’t have an application at all, it’s not correct to make you believe that you can use at least a simple mode, the most basic option is behind a paywall ### 1/5 — ужас!!! *2026-01-25* не приложение а ужас какой-то, мало того что грузило 10 минут, так ещё и не дают сохранить, говоря купить премиум. ### 1/5 — Все платно *2026-01-11* Мда уж ### 1/5 — :)dope *2026-01-08, version 3.2* So good ### 1/5 — Grid Lines! *2025-12-13, version 3.2* I noticed after a lot of work that the upscale photos have faint grid lines on them that are being added by the app. ### 1/5 — Terrible *2025-12-06, version 3.2* The picture sharpens a lot but….. the eyes change which is not cool at all!!!! This need to change NOW!!!!! I want these pictures of the women I love a lot to look the same as when I enhance them to look The eyes of the women change and looks nothing like them at all!!! ### 1/5 — DO NOT BOTHER *2025-11-24, version 3.2* What a waste of time. You can’t save any image without upgrading to the pro version. It’s a joke. Is there negative stars for wasting my time? ### 1/5 — 不完全&品質悪い *2025-11-16* 確かにアップスケールとかは出来るんですけど画像にある字幕とか、画像の一部分だけアップスケール出来なかったりとか不完全な所が目立つ。 ### 1/5 — Eyes are not upto the mark after upscale *2025-11-03* Don’t buy premium ### 1/5 — Ffgghh *2025-10-25, version 3.2* Try ## Most praised reviews (10 highest-rated) ### 5/5 — 값어치 이상!! 👍👍👍 *2026-08-02* 요즘 화질만 올리는 업스케일링 사이트들 다 월간 구독에 비싸거나 가격대비 성능은 품질이 좀 떨어지는 편인 것도 많았는데, 우연찮게 찾은 이 앱은 1회성 결제인데도 좋네요!! 진짜 유레카 외쳤습니다 ㅎㅎ 잘쓰겠습니다 감사합니다! ### 5/5 — Норм *2026-06-05* Норм ### 5/5 — Exceptional *2026-03-02, version 3.3* Professional Quality ### 5/5 — Love it *2026-02-14, version 3.3* Use this app on a daily basis, thank you ### 5/5 — No Subscription Just One Time Fee *2026-02-11, version 3.3* Thank you for making something that people will actually want to pay. $4 one time fee is very reasonable and the app is very good! ### 5/5 — G *2026-01-20, version 3.2* Good ### 5/5 — Great app *2026-01-03, version 3.2* Really useful ### 5/5 — App *2025-12-25, version 3.2* Really good ### 5/5 — Nice *2025-12-21, version 3.2* Good ### 5/5 — Pic *2025-12-11, version 3.2* Great quality --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
