5/5Awesome!
This app is so convenient. It’s a great way to learn and test with so many high quality images and concise explanations. I like that I can use my phone or iPad. It’s an easy way to quiz myself when waiting in line for coffee or on public transit. Great work!! Medical students will find this very helpful in reviewing histology and prepping for Step 1.

5/5Great for familiarization and learning functions
This is a fantastic resource. I wish there was a next and back button. I am not a huge fan of the randomness all the time, I want to cover one specific slide for all 7 labels (if there are that many) right in a a row, but it jumps around to random places.

5/5Good for histo
I’m a second year medical student. Helped a lot with histology. After studying I would use this app to get a large volume of images. I would like to see a feature in the app to view infectious tissue such as osteomyelitis.

5/5Histo! Deserves the !
This app is so helpful! The pictures are good and the descriptions are clear. Everything is easy to navigate. I especially like being able to mark slides that give me trouble and go back anytime I want to look at them again.

5/5Great app!
Images are really good, with several different views of most tissues and organs. Quiz mode was great for testing my knowledge after going through things in Learn mode. Subtopics option let me zero in on stuff I was having trouble with. Very useful learning tool.

1.2.2
The layout has been updated so that micrographs display properly on the new iPad mini (6th generation).
1.2.3
The layout for iPhones has been updated to accommodate an increase in the font size of image descriptions and instructions, which facilitates readability. This requires text scrolling in some cases.

This replaces the single window of Main topics that required tapping to expand and contract the list of items. •The Search Menu has been reorganized and simplified. •The process for identifying and displaying specific slides has been simplified.
