About this app

Our team is grateful for all of the feedback and emails that have been sent to help us make this app better through the pandemic. The critical community is a lot of fun. There have been a lot of changes to Critical, but this is by far the biggest one yet. During this time, we have done a complete overhaul of the app's UI to make it even better for users. Here is some of the things the team has done based on your feedback.

Nice IPAD Version, great on the iPad mini. Bugs have been fixed in this new version (30). The 02 section for the EC135 tank has been updated to fix them. The ability to change the conversion factor. Added Bell 407 to the list. All over the app, there are new calculators and layouts that you can use. The Peds section added fun a widget that helps you do CPR. In addition, the app's UI has gotten better. This includes the ABG page, the drip (UI changes to the drips show how long it will take to run the next dose), pharmacology (customization), and a lot more. Calcs now have RSBI and BMI added. Smoother animation changes. Of course, there will be speed improvements, major UI changes, small bug fixes, and more!


Please enjoy and let us know how your new Critical experience is!

Ratings and reviews

It won't save a calculator as a favorite. It's REALLY annoying to have to accept the disclaimer before accessing the app EVERY time-ESPECIALLY when in a hurry. Would be nice to add a dose calculator that is accessible direct from every weight based dose med (eg if I'm looking up Norepi..the dose calculator would be at the bottom with the weight based dose already set - all I need to do is input pt weight).

It is a good idea in principle, but none of the weight-dependent doses update for any change in reported weight. Several of the clinical info pages are incomplete, and those that do have info have several typos. A lot of work has been put into the design of the app, but the animations are over-performative without adding any benefit to use. The same effort needs to be put into clinical facets as was to design aspects.

Ground critical care transport & fixed wing flight nurse. The app has excellent features, but 2 big issues keep me from giving it 5 starts. 1) The app only works with an internet connection. I can't get an internet connection at 40,000 feet, so the app is essentially useless in any environment with spotty to no internet service. I'd much rather see a product that can operate 100% without internet. 2) The critical care drip calculator user interface is wonky-the cursor isn't visible when entering
