Tried to edit a picture (add a quick watermark) and the app wouldn’t launch. It was continually stuck in the splash screen. Tried and wait it out and the app wouldn’t launch crash. Since I have updated my iOS and even phones thought it might be an issue. So I deleted the app along with the data since I had bought the upgrade years ago. Downloaded the app again, and this time it launched but to my surprise? It is now a monthly subscription?! I tried to restore my purchase and it says I hadn’t bought anything. This is when I realized what has happened: lock out the legacy purchasers to make them pay the new monthly subscription model. For these prices, I would rather switch to photoshop express. Too bad, this was a great app for very casual users. I don’t need anything AI (I believe the selling point because of the tokens used). 2 stars because i had been using it and it’s great for SIMPLE edits ### 1/5 — Bug with pointer *2020-11-26, version 1.6* The pointer must not be just under my finger. This is very annoying when erasing or recovering background. If the pointer is just under my finger touch, I can’t see what I erase, recover or draw. Please fix this annoying issue, it makes the app I paid for useless for me. ### 5/5 — เสียเงินแต่ได้ใช้ *2020-09-17, version 1.6* เสียเงินแต่ได้ใช้ ### 5/5 — Brilliant *2020-09-04, version 1.6* Just what I was looking for, so much fun ### 5/5 — Saving strikers in the Dash board issue *2020-07-10* I was subscribed for Knockout HD plus sense few months for 1 year but right my account shows that I’m regular accountant and I cannot access my uploaded stickers I’m getting messages saying that I can only access 5 pictures and if need to access more of my pictures I should subscribe again on time that I’m already subscribed until June 2021 as showing in Apple subscriptions. Would you please review my account and resolve this issue ASAP and please contact me soon for any additional information. Note: I did not find any contact information for your company in the app reviews or in your applications!!!? ### 5/5 — Awesome! *2020-05-24, version 1.6* I love, love this app! 🥰 Improvements make it even better. Thank you! 😁💕 ### 5/5 — Muuuuito bom *2020-05-05* Nota 1.000✨ ### 4/5 — Terrible *2020-04-17* Worked great until something changed , now it just crashes all the time ,avoid much better out there . ### 2/5 — New Update *2020-04-13* I have used this App for the past few years. It was brilliant. Couldn’t fault it. Then the most recent update came out. It has really gone down hill. Nothing has improved. Only got worse. Such a shame. I have been playing around with the new update since it has come out and there is nothing that has got any better. Just worse. There are so many bugs on this version. When you return to your work something has always moved. Not impressed. Such a shame. I really hope they go back to the old version. ## Most critical reviews (10 lowest-rated) ### 1/5 — Used to be *2026-06-28, version 1.6* Used this app a lot years ago, then here recently it has become extremely glitchy. It closes on its own and it’s pretty annoying. Still try to make it work ### 1/5 — Disappointment App *2026-05-12, version 1.6* I’ve used the app for many years but now it’s only gotten worse. The sticker option leaves residue on photo adjustments. Goodbye. ### 1/5 — Not updated *2026-04-15, version 1.6* ซื้อ แต่ล่าสุดเปิดแอพไม่ได้แล้ว ### 1/5 — Ai cut fake *2025-08-25, version 1.6* Not working. Won’t give money back ### 1/5 — ไม่คุ้ม *2023-03-01, version 1.6* ไม่คุ้มนะ ถ้าเทียบกับ proknockout การตัดภาพไม่คมขอบเส้นไม่ชัดเจน เสียเวลาต้องมาแก้ไข ในขณะที่ proknockout ตัดเส้นได้คมกว่า ราคา 69 ไม่คุ้มเลย ข้ามเรื่อง hd ไปเลย ต้องซื้อเพิ่มอีก! ### 1/5 — Nul *2022-08-18* Je dé conseille. Très mauvaise ergonomie ### 1/5 — NOT HAPPY!!! *2022-04-09, version 1.6* I subscribed to the pro version and then this HD version popped up. I thought, Ok, $1.99 I will try it! WHAT A RIP OFF!! I want my money back! This app is so full of distracting adds and nothing works the way it says it will. Plus I am getting nag screens to upgrade THIS version! What was the $1.99 for? I’ve been using photo editing apps for years. Only reason I had to find a new one is because one that I was very satisfied got discontinued! So disappointed with this app! ### 1/5 — Ein sehr schlechter App *2021-09-19, version 1.6* Tut absolut nicht, was er verspricht. Einfach 1,99€ abkassieren für einen App, der überhaupt nicht funktioniert. 👎👎👎 ### 1/5 — ảnh mờ *2021-03-04, version 1.6* lưu ảnh ra mờ quá cần cập nhật thêm tính năng mới thông minh hơn lấy hình chuẩn hơn tự động xoay hình thẳng đứng ### 1/5 — Worst application ever *2020-12-18, version 1.6* Kept exiting out and nothing worked ## Most praised reviews (10 highest-rated) ### 5/5 — Тамара *2025-12-21* Пользуюсь много лет:) спасибо хорошая ручная вырезка. Вылетело сохранение в прозрачный фон, как исправить? ### 5/5 — มือใหม่ *2022-03-20, version 1.6* ดีครับใช้ง่ายครับ ### 5/5 — Perfecta *2022-03-10, version 1.6* Llevo años con ella y esta muy bien para hacer montajes o retocar un poco las fotos, tiene muchas opciones para escoger. ### 5/5 — Excellent *2021-08-03, version 1.6* Excellent ### 5/5 — Recomendo a instalação do aplicativo ⭐️⭐️⭐️⭐️⭐️ *2021-04-12* Parabéns aos idealizadores e desenvolvedores do aplicativo ### 5/5 — One of the best *2021-03-12* I do a lot of “sudden” photographic images with kids in primary school. I might put them on the moon, or include them in a picture with their favorite football team, or chatting with Mr Trump, etc. this app is one of the most accurate for cutting out an image, and it does not cost a fortune. It's great! I won't pay for subscription though. Everyone has got on the subscription bandwagon. If I had to renew subscriptions for all the useful apps it would cost a fortune each year. Also I use most apps occasionally so don't get my money's worth. ### 5/5 — Great App *2021-02-02, version 1.6* So easy to use, transform pictures in a breeze! ### 5/5 — Excellent product for quick and solid results. *2021-01-17, version 1.6* Best by far in my mobile ### 5/5 — Great app *2020-12-26, version 1.6* The best app ever second to none ### 5/5 — Fun *2020-12-11, version 1.6* I have sooo much fun with this app! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
