Fortis results screen: coaching moments for a snatch - Strong finish through the hips at 0:06, Early arm bend at 0:04, Catch drifts forward at 0:10 - each with a tap-to-play timestamp
Straight with you

If we can't measure it, we won't make it up.

Film front-on and Fortis will never invent bar-drift numbers it can't see - metrics the camera angle can't support are left out, and the app tells you why. Film side-on and you unlock the full bar-path record.

How it works

Three steps between you and better lifting.

Fortis onboarding screen titled Film it right: side-on to the bar, full body and bar in frame, phone stable at hip height
01

Film your lift

Side-on, full body in frame, phone at hip height. The app shows you the framing once and checks it for you after that - no tripod rig required.

The AI reads it like a coach

It classifies the lift, then reads it phase by phase at six frames a second - first pull, contact, turnover, catch. Deep Analysis on Elite goes frame by frame.

Coaching you can scrub

Every cue carries a timestamp. Tap it and the video jumps to the exact moment - the early arm bend at 0:04, not "somewhere in the pull."

What you get

Built like a coach thinks.

Technique memory

It remembers your early arm bend - and notices when it's gone. Your faults follow you across sessions, so the coaching builds instead of repeating.

Bar-path overlay

Your bar's actual path traced over the video - computed on your phone, calibrated off the plates in frame.

A coach that speaks

Live sessions with a natural voice between your sets - ask why the bar crashed and get an answer while the barbell is still loaded.

Deep Analysis

On Elite: a frame-by-frame phase breakdown - setup, first pull, transition, second pull, turnover, catch - each read on its own.

Works offline

Basement gym with no bars? Film anyway - the quick check runs on-device and the full analysis queues until you're back in signal.

Drills that target your faults

Not a generic warm-up library - each drill is picked because of what your last video showed, with sets, reps and what to feel for.

For coaches

The coach's eye between sessions.

Your athletes film their lifts and bring you what Fortis found - timestamped, not remembered. Each athlete builds a technique history you can actually look back through.
