User reviews

Better mobile use than apex but needs improvement.

Finding MA to be much more user friendly and experience on mobile than APEX for continuing ed, and it has elements that vastly improve on what Vargo/CoExistinf offers. However, the app is in desperate need of a few improvements:

1) Most importantly, a way to change font size.

2) A per-lesson way to leave feedback or suggest corrections. For $450, it bums me out to see major typos and sentences that just drop off in the middle of a thought. You have a lot of content, and proofreading is hard, but there’s no simple way for users to help you correct mistakes, and this devalues your product.

My go to

Amazing resource. Constantly updated with current evidence. And gives little snippets of evidence based practice updates in email.

Exceptional

By far the best companion app for anyone in the anaesthesia field.

Improving all the time

I’ve been using MA for at least 5 or so years. It’s a great app and each update is an amazing improvement. I recommend this app to colleagues all the time. It’s easy to navigate and easy to read especially in the OR. Keep up the great work!

The best anesthesia resource

Love this app so much for my anesthesia practice. Easy to use, comprehensive, relevant information that’s actually useful for everyday practice. Worth every penny
