Your Go-To Tool.
Every Day.
The professional app built for Gray Institute®–trained specialists.
You have the education. Now you need the tool that puts it to work — fast, simple, and built for your day-to-day. Screen clients with 3DMAPS®, build individualized programs grounded in Applied Functional Science®, and assign them in seconds. This is how AFS® gets applied in the real world.
The Science Behind Everything.
Most professionals were taught what the body can do. Applied Functional Science® teaches you why it moves the way it does — in three dimensions, as a fully integrated system. It's the reason Gray Institute® has trained over 250,000 movement professionals across 45 years. And it's the principle baked into every single tool in this app.
The result? A principle-based system that lets you design a limitless number of individualized assessments, treatments, and training programs. No one-size-fits-all. No plateaus. Just outcomes — for every patient and client, every time.

Work 1-on-1 with a Gray Institute® team member to configure the app for your practice. Solo PT, performance coach, or full clinic — we set it up to match exactly how you work.
Run a 3DMAPS® screening, identify movement priorities, build a personalized AFS®-based program, and assign it to your client in seconds. From first screen to delivered workout — that fast.
Assess. Analyze. Design. Coach.
Most apps just deliver workouts. The Gray Institute® App delivers a proven process — the same Applied Functional Science® workflow you learned through certification, now built into every client session and extended through the Vitality® client experience.
Assess
Run a full 3DMAPS® screening directly in the app. Capture mobility and stability data across all three planes with built-in reference video — in minutes, not an hour.
Analyze
The app generates your client's Relative Success Code and Performance Track automatically — surfacing movement priorities and the precise starting point for individualized programming.
Design
Filter 300+ AFS®-based templates by certification track — CAFS®, FSTT, 3DMAPS®, Golf, and more — or build fully custom programs from the full exercise library.
Coach
Assign through the Gray Institute® App, then coach beyond the session through the Vitality® companion app — with workouts, readiness tracking, education, and measurable progress all connected.
