Fixed the back button that could stop responding after opening the same screen twice.

The code entry card on the upgrade screen now has a button that closes it, and a tap outside the card closes it too. The store listing now names and links every official source behind the medical content, and states clearly that this is an independent app, not a government one.

The rating button on the home screen now opens the store page so you can leave a review. The app also waits until you have used it on a few different days before asking for a rating.

The TCCC reference now follows the CoTCCC TCCC Guidelines dated 01 MAY 2026, up from 1 August 2019. Clinical text in the reference and the field tools is quoted from the guidelines, and each section names the guideline section it comes from. The Sources screen shows the guideline edition and lists what the app does not cover. Reference paragraphs no longer split a sentence in two. Fixed: MARCH drill ticks now stay when you switch tabs. Fixed: the upgrade screen's buttons stay above the keyboard. Training and reference only. Follow current guidelines, your medical direction, and your scope of practice.

NEW: TOURNIQUET CLOCK Log the time a tourniquet went on, per limb and per casualty. The clock keeps counting while the app is closed and after a restart, and flags the 2 hour reassessment point and the 6 hour limit. Free for everyone. The app now opens on the field tools instead of the chapter list. The TCCC Casualty Card exports a formatted DD Form 1380 you can hand off. The 9-Line MEDEVAC request and the Casualty Card now save as you type, so a closed app no longer loses what you entered. New app icon. Training and reference only. Follow current guidelines, your medical direction, and your scope of practice.
