### 5/5 — Fantastic!!

*2024-07-01*

Most medical apps do not survive iOS software updates. CytoAtlas is the exception with straightforward content and non of the bugs with most medical apps. Great job to the writers of this app.

### 1/5 — Stopped working.

This app won’t even open up for me anymore. It used to be an amazing tool in procedures. Please fix it!!

### 5/5 — Exactly what I've been looking for!

I'm a 4th year med student applying to Pathology programs for residency. This app is exactly what I need for studying/review of cytology- from the very basic to complex disease. Thank you!

*2015-03-02*

As a medical student interested in Pathology, this is a gold mine of practice. Great images and explanations. I'm a fan of the categories and the zoom function.
Odd issue: wouldn't properly load the first few days I had it. I deleted and reinstalled the app a couple times before it got past the loading screen. 
Possible future addition: ability to submit slide images to the database would be a great way to expand it!

### 5/5 — Great pictures and explanatory text
