The PT test decides your career.
Sentinel makes sure it doesn't end it.
Your integrated training, nutrition, and test-day brain for the USAF PFRA. Built for the 2026 standards — WHtR body composition, the 2-mile run option, and every cardio component.
Most PT apps tell you a score.
Sentinel tells you how to pass.
Your score doesn't live in a spreadsheet, a pace chart, and a nutrition app somewhere else. Your career doesn't either. Sentinel is one integrated brain for your PFRA — calculator, training, nutrition, and test-day coaching in one place. Built by a USAF veteran for the people who carry the same uniform.
Already in your pocket.
Everything below is live on the App Store today — free to use, no ads, no account required. Sentinel+ is an optional upgrade.

What we're building next. Some lands in the free app; some powers Sentinel+.
