Army Fitness Calculator APP
In addition to calculating the ACFT, the app also has sections to calculate Ht/Wt and BF%, Promotion Points for Semi-Centralized Promotions, and APFT.
Along with the calculators, the app has the doctrinal verbiage for the event instructions; a link to the Army's ACFT page for more information on the implementation, videos, and resources; and a settings page to set the variables that aren't going to change every time you open the app (i.e. age, gender, aerobic event, etc.).
Upgrading to the Premium version allows you to save scores for yourself and your Soldiers, download scores to official DA Forms, and chart progress. The Premium version also removes ads.
