Font size

I hope this is just an oversight and that it can be easily fixed with an update but, there is no way to increase the font size. I’ve own previous versions ie 17 and font size adjustment was available, I ask you to please add that feature, when you are more than 50 like me, that feature is a lifesaver.
Also, I wish a highlighting feature was available, just like MedStudy does.
Thank you, I hope you can fix it.

Developer Response ,

Thank you for your feedback. Version 1.2.1 added the ability to increase the font size.

No highlighting, no screen split. Do not recommend. Bad ebook features.

Good app, with all fancy features, but without a basic and fundamental ebook qualities such as text highlight and inability to use spilt app and write notes in the same time. Would not recommend digital version, very difficult to read and not taking notes and not highlighting text. Constantly feeling like holding my self from not highlighting. Feels like ebook from 1999. If it is about copy right, you can copy paste all text wherever you want but not screen split, no note taking or highlighting... Needs a lot of improvements in “ebook features”. Imaging buying a book but not being able to take notes in the same time. This guys have no idea about medical learning. Emailed support team 6 months ago, received polite response, with no improvements in reading experience in last update so decided to write critical review.

Good app with room to grow

Good design and easy to use. Liked how the tables, images and questions are integrated into the text. Dark mode is appreciated, too.

Suggestions: if possible, please add the ability to highlight text in the book or questions. Changing fonts would be nice, too.
