Comments on Critical - Medical Guide for Android

★★★★☆ George Olschewski · Dec 8, 2020

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

★★★★★ Carlos Justin · Mar 18, 2020

Great app, used for while when I had an iphone. Nice to see on android. Would like to see initial vent setting calculator (TV based on IDB and or goal TV with IDB, MV etc.)

★★★★☆ Shiva Chanderan · Aug 29, 2023

I gave 4-star rating and would like to give 5-star rating, but you need to fix some issues. Un able modify small weight like 1.2 kg etc., if you fix this on android version it would be better for everyone, and we will be happy. Hopefully you will respond soon and fix this issue as soon as possible.

★★☆☆☆ Yannick Sharras · Apr 2, 2023

Good Idea... It's misleading in drips though... The drug dosages are not lined up for you to modify how you want to give. For example, you want to start a ketamine drip. 500 mg of key in 500mL bag to give 1 mg\kg\hr... The app says mcg\kg\min, so you put that in and your drip is wrong because that data point is really asking for mg\kg\hr but says mcg\kg\min. I think all those data points should be modifiable like I should be able to change it from mcg\kg\min to mg\kg\hr and that dosage slider bar.

★☆☆☆☆ J McD · Sep 20, 2025

This app is a major letdown for critical care providers. It's supposed to simplify drug dose calculations but the features are incredibly buggy. You can't change the patient's weight or drug concentrations, which makes it unreliable and unsafe for clinical use. The O2 cylinder calculations are also consistently wrong. This app is more of a liability than an asset. Avoid at all costs.

Description by The Barringer Group, LLC Written by the developer, not by AppBrain. Click to read.

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!
