There are several other code blue apps and you're wondering which one to pick so I'll just cut straight to the chase. You want a simple, intuitive, and customizable app to help you track medications and events. You don't want a bunch of other tools that you'll never use and that will clutter your screen (and if you did there would be a whole separate section for that, which needs to be enabled) If you're a pharmacist or registered nurse in charge of tracking medications, then I think you'll find this app very useful. If you're a provider (MD, DO, ARNP, etc) or paramedic MAYBE you might find some use out of this. I've built this app in a way to allow for customizable ACLS navigation (checklists, RSI, Hs/Ts). Please use the 30-day trial to see if it meets your needs and if it doesn't let me know how I can improve it. The app is dirt cheap. It's $0.99 every 3 months. That's less than the price of a cup of coffee every year. The only reason I'm really charging for it in the first place is because it cost money to keep apps on the Appstore and I don't want to run ads on something like this. Please try it out and leave a review. Thanks, Brian Mun, PharmD codebluetracker@gmail.com Terms of Use EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
