*2026-06-27*

Used it for the first time last month and I loved it so much! But now, after the latest update, it keeps crashing when I try to export the photos as video, no matter the length of the video. Same experience across iOS and iPadOS. Please fix this!!

Serve para diagnóstico porém não consigo fazer medições no iPad. Como trabalho com implantodontia, não faz muito sentido.

### 3/5 — Limitações no tablet e iPhone

*2025-12-15*

Não consigo fazer medições no iPhone e nem girar a referência cruzada no tablet. Tem que melhorar isso aí

### 4/5 — Suggestion

*2025-12-08, version 3.2.0*

Please allow measurements while on MPR

### 4/5 — Really good- missing one thing

*2025-11-30*

It’s unable to read JPEG2000 Lossless files, preventing me from seeing some results. Add that feature for 5 stars

**Developer response:** At the moment the app doesn't support 2000 Jpeg lossless. However, you can view your file on IMAIOS DICOM Viewer Web (on IMAIOS website), which does support this DICOM format.

### 4/5 — Awesome Free Resource with Small Missing Features

*2025-06-23*

So happy to find this app to view my MRIs from the last couple years! Definitely recommend! Though I did find myself wishing for a couple features that would’ve been very helpful for me, overall awesome quality from a free app :) Thanks Devs! 

The good: Importing everything was very simple; I couldn’t get the Folder option to work, but multi-selecting files worked very well and the program automatically knew which of 9 studies to add each file to, which was very impressive. The interface is also really easy to use and intuitive, worlds better than the free image viewer that came in my DICOM zip file from the hospital. 

Suggestions: With the available annotation tools, it would be really nice to be able to add simple straight or dotted lines to help visualize reference points (I just used the distance measure tool, but the additional numbers add clutter to what I’m trying to see). The other thing I really wish I was able to do is pull up images from 2 different studies side-by-side to compare; not even rendered as a full-scan stack, just maybe if certain frames/layers of studies could be flagged or duplicated into single images to work with? 
I haven’t spent a ton of time in the software, so maybe haven’t figured out all the tools yet, but I wasn’t able to find an obvious way to do these things and thought they’d be useful for others too.

**Developer response:** Your feedback is greatly appreciated, and we'll consider your suggestions for future improvements.

### 1/5 — Não abre os arquivos

### 1/5 — Buggy

*2026-03-31*

Two .zip imports gives errors "Unable to open file DICOMDIR IM5", so both Ultrasound and X-Ray missing Image 5. Also the Ultrasound has 67 images, but can only view the first one? Deleted - will find something else.

### 1/5 — Does not work on an iPad Pro

*2025-12-15, version 3.2.0*

It does nothing

### 1/5 — Force close

*2025-10-25, version 3.2.0*

Every time I try to access the files on this app it force closes the app

### 1/5 — Waste of time

*2025-09-16, version 3.1.0*

This is an embarrassment of an app. How did Apple approved this?

### 1/5 — Not supported

*2025-06-21, version 2.7.0*

Says it doesn’t support JPEG 2000 which doesn’t make sense. Why would a web viewer support something while a dedicated app wouldn’t?

### 1/5 — Mueble to open Dicom imagen

### 5/5 — Молодцы

*2026-04-14*

Немножко сбился с толку при импорте, залил из айклауда. Сделайте пожалуйста возможность прямой заливки на устройство, это когда приложение доступно во вкладке «Файлы».

Не медику сложновато разобраться, неплохо бы какую инструкцию, так сказать, что тут к чему 😊

С управлением вопросов нет, тут интуитивно понятно.

**Developer response:** Thanks for your feedback! We appreciate your suggestions and will keep them in mind for the future.

Used to view DICOM zip file of my MRI

### 5/5 — 不用改文件后缀特别棒

*2026-02-01*

最开始下载了另一款可以读dcm文件的中文软件，但是电脑上下载的文件无法显示后缀更别谈论更改，因此我尝试了半小时在如何显示并且更改文件后缀上，天菩萨我第一次知道一个文件的格式可以是文件。怒而选择了你们这款全英文的，比那款好用多了还不用改后缀……感动的流眼泪了🥹🥹🥹

**Developer response:** 谢谢你的反馈   我们很开心你喜欢这个应用！

### 5/5 — Супер!!!

*2026-01-22*

Отличное приложение. Очень удобное. Работает с PAC серверами. Только не хватает DX формата. Будете ли добавлять в обновлении? Корректировка: Не полностью разобрался с настройкой сервера. Нашел, где включит. Активно пользуюсь, все работает!!!

**Developer response:** Спасибо за ваш комментарий! Мы рады, что Вам нравится приложение.

### 5/5 — 五分好评

*2026-01-22*

特别特别好 五星推荐 意见 1能否支持多窗口模式对比模式 不同时期放射医生阅片需要不停切换对比很麻烦 2打开影像后没有时间 要返回才能看到时间
