### 3/5 — Prompts about using location data

*2025-12-27*

The app inverts images as needed. However it keeps prompting to say it’s using my location data. Kind of sketchy and annoying after the first few photos. Why does a photo inverter really need our location data?

**Developer response:** Thank you for your feedback. The app itself does not need your location to invert photos. The prompt may be related to the advertising service or its privacy settings, but we understand why this feels unnecessary and concerning. We’ll review the configuration to reduce or remove repeated location-related prompts where possible.

### 2/5 — Shame about the ads!

*2025-12-19*

Ok results but  the ads make this pretty unusable

**Developer response:** Thank you for your feedback. We’re sorry the ads affected your experience. As the app is free, advertising helps support its development, but we’ll continue reviewing the frequency and placement to make it less disruptive.

### 3/5 — Please make it better

*2025-07-07*

The app works well but it needs two main improvements.

1. Remove the Complete dialog when saving, it's completely unnecessary and a very annoying additional pause and click. Slows everything down. 

2. Add a filter to the file picker to show all light or all dark images. Having to scroll up and down to find the one light or dark image is more of the annoying time sink as in 1.

Thank you!

I'll adjust the review once improvements are done.

**Developer response:** Thanks for the detailed feedback! In the next update, saving is now a single tap — the confirmation and the "Complete" pop-up are gone, replaced by a quick "Saved" toast, so it's much faster.

On filtering the picker by light/dark images: unfortunately iOS's system photo picker has no way to filter by brightness — Apple only allows filtering by media type. Delivering that would mean building a custom in-app gallery that scans and classifies your whole library, which we're evaluating as a separate, larger update. Appreciate your patience!

### 4/5 — It works

*2024-12-26*

It simple works but output JPG seems highly compressed? Not sure what is limiting it.

**Developer response:** Thank you for your feedback! We’re glad the app works well for you. We’ll review the JPG export settings and look into improving the output quality and reducing unnecessary compression in a future update.

### 5/5 — 确实没有多余的步骤

*2024-11-05*

很简洁

**Developer response:** 谢谢您！我们尽量保持简洁易用。

### 5/5 — Good app

*2024-09-22*

This app is actually good for making ur photos invert and you don’t have to pay a fee?? Like other apps try to charge people for simple image editing but this on makes it simple by adding 3 buttons. Simply pressing on the third letting you choose the photo you want to invert, the first button being the invert filter, and the second being download.

**Developer response:** Thank you! We're aiming to keep it as simple and user-friendly as possible.

### 5/5 — 名副其实

*2024-05-23*

很好，没有任何多余的步骤，一步到位！

**Developer response:** 谢谢您！希望您使用愉快！

### 5/5 — Reverse Screenshots

*2024-02-10*

I was able to reverse (dark/light) colors of screenshot taken at night (dark screen mode) so as to reduce toner (or ink) consumption when printed.

**Developer response:** Thank you! Enjoy using the app!

### 5/5 — 👍

*2023-08-01*

Did not reduce the quality of a 4k image. 

Works perfectly as intended.

**Developer response:** Thank you! Enjoy using the app!

### 1/5 — 앱좀 잘만드세요

*2023-07-17*

원본 이미지크기 지멋대로 줄이고 원복 삭제시켜서 복구도 못하게 만들어 놓고 배경화면 손수 만든건데 날라갔는데
좀 어플  만들꺼면 완성도있게 만드세요 
편집 프로그램이 사용자가 원하는것만 들어줘야지 지멋대로 데이터 바꿔놓게 만들지말고 
진짜 별 반계도 아깝네

**Developer response:** 앱 사용 시 새로운 이미지를 저장하므로 원본 이미지는 삭제되지 않을 것입니다. 원본 이미지 크기가 축소되는 부분에 대해서는 개선을 검토하겠습니다.

### 1/5 — 広告がチカチカする

*2026-06-23*

広告がチカチカして気になるため、落ち着いて作業出来ない。

**Developer response:** 無料アプリのため広告をつけさせていただいております。広告なし課金などの検討もさせていただきます。

### 1/5 — Too many ads!

*2026-03-30*

Takes so long to get through ads! Shame, otherwise a useful resource.

**Developer response:** We’re sorry for the inconvenience. We found and fixed an issue that caused too many ads to appear on some devices. Please update the app to the latest version and try again. We’re glad you otherwise found the app useful, and we appreciate your feedback.

### 1/5 — Not the best sorry :(

*2026-03-14*

It works if the negative image effect is all you want but it’s not the best sorry!

**Developer response:** Thank you for your honest feedback. The app is designed as a simple tool focused on the negative image effect, but we understand that it may feel too limited for some users. We’ll consider ways to improve it while keeping it easy to use.

### 1/5 — Works, but too many ads

*2026-03-01*

The number of ads makes this app practically unusable, unavoidable 30s ads at almost every click, what an awful experience that was…

**Developer response:** We’re sorry that the number and length of the ads made the app difficult to use. As this is a free app, ads help support its development, but they should not interrupt nearly every action. We’ll review the frequency and placement of the ads to improve the experience. Thank you for your feedback.

### 1/5 — Marketing advertising

*2026-01-29, version 2.1*

This asks to track all your I phone activity, it floods advertising and even fires up your Safari. Yes, I am VERY NEGATIVE , now I gotta check for scams. Apple please review your promoting and offers in the App Stire.

### 1/5 — Electronic pathogen vs scam vector

*2025-09-20*

"Ad" pretending to be a malware detector told me phone was infected but I could fix it by participating in their scam.  Deceptive security claims are harmful, especially to the least knowledgeable.  Unethical behavior earns 1 star regardless of functionality.

**Developer response:** We’re very sorry that you encountered a deceptive security advertisement. Ads are provided automatically by a third-party advertising network, but misleading malware warnings are not acceptable. We will report and block this type of ad where possible and review our ad filters to help prevent similar ads from appearing again. Thank you for bringing this to our attention.

### 1/5 — Ads

*2025-07-27*

Way too many

### 1/5 — Ads Make It Unusable

*2025-07-02*

The recent update causes the ads to make the app completely unusable. You can’t click out of the adds and when you watch the ads it just plays another one. Please fix.

### 1/5 — So many ads could not even get it to process a picture.

*2025-03-23*

So many ads could not even get it to process a picture.

**Developer response:** We’re sorry for the inconvenience. We found and fixed an issue that caused too many ads to appear on some devices. Please update the app to the latest version and try processing your picture again. Thank you for your feedback.

### 5/5 — It does exactly what it says!

*2025-06-02*

Taking screenshots of apps and webpages when dark mode is enabled means a LOT of black background. 
Easy on my eyes, but outrageous for my printer ink levels. 
While I’m basic, and printing screenshots like photos, I definitely don’t need photo quality or the black background, just the information/text. 
And for the few things I need to print (at this time) a full featured photo editor is not warranted. 

This does exactly what I want - 
roughly invert black background and white text to white and gray backgrounds and black text, and blue banners to peach (lol) 
And when I want it - 
NOW, 
And with the most basic of commands - Files (find image) symbol, 
Floppy Disk (save to same location as original image) symbol 
Circle Arrows (convert image) symbol

No help file (don’t need)
Minimal text (press to go past splash ad to app)
No request for donations or purchase (ad-supported)
Big splash ad on launch, then banner ads on bottom (nothing objectionable, yet)

And since I print plain paper, draft quality, black and white, this photo is practically a document, and is easier on my black printer ink levels.  

And when you select your image, while you see your Photo Library/Album, the app only sees the image you select, convert, and save. 

Good, so far. 
Will update if any problems noticed in future.

**Developer response:** Thank you so much for your detailed and thoughtful review! We’re delighted that the app does exactly what you need and helps make screenshots easier and more economical to print. We’re also glad you appreciate the simple controls, minimal design, and the fact that only the image you select is accessed. Your support and feedback truly mean a lot to us!

### 5/5 — 一键转化！

### 5/5 — Perfecto!

*2025-02-09*

What - a - blesssing. Just what I was going insane looking for. Simple, intuitive, effective, and it does what it says it does. Even the ad banner at the bottom is no big deal (devs gotta eat too). Overall a godsend. 5 Stars!

**Developer response:** Thank you so much for your wonderful review and understanding! We’re delighted that the app was exactly what you were looking for and that you found it simple, intuitive, and effective. Your support truly means a lot to us!
