Guides & Tools

Everything here is free and nothing asks you to sign up. It is written for people who are training for something specific and want the part that is actually useful rather than the part that is motivational.

Calculators

Scored from the same tables the app uses, so the two can never tell you different numbers.

Calculator

Ruck Pace Calculator

Pace, finish time, per-mile splits and where your pace sits against the 12-mile standards. Optional load-carriage energy estimate.

Calculator

AFT Score Calculator

All five Army Fitness Test events against the current tables, under the general or the sex-neutral combat standard.

Calculator

USMC PFT Calculator

Pull-ups or push-ups, plank and the three-mile run, with your class and what the push-up cap really costs.

Calculator

USMC CFT Calculator

Movement to contact, ammunition lift and maneuver under fire, scored against the current tables.

Calculator

Navy PRT Calculator

Push-ups, plank and your choice of run, swim or row — because they are not worth the same points.

The app the guides come from

Lensatic tracks runs and rucks by GPS, grades land navigation practice against your plotted points, and builds its plans and standards around the school you are aiming at — from basic training to SFAS, BUD/S, Ranger School and OCS. Forty training plans, twelve schools of lessons, and a standards board that fills itself in from what you log.
