### 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.

### 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.

**Developer response:** We are sorry to hear that you are experiencing issues with our app. Could you please email contact@imaios.com explaining your problem (if needed with a screenshot)? This will greatly help us to fix your problem.
