Rank your lifts.
Fix your form.
Film your set. FormX scores your form with AI, then ranks the lift on a ladder from Iron to Apex — and sloppy reps cap your rank, so every tier you hold is one you actually earned.
Film the set. Get the rank.
One form check does both jobs: an AI form score with the exact fault and next cue, and an instant rank for the lift. Thirty seconds from racking the bar to knowing where you stand.
Phone against a water bottle is enough. Normal gym angles work.
0–100, rep by rep — the main fault and the one cue to fix it next set.
Weight × reps × bodyweight, mapped to strength standards, gated by form.
Every exercise ranks separately — your squat can sit in Obsidian while your bench grinds through Steel. Muscle-group and overall ranks roll up from the lifts underneath them.
Ranks you
can’t farm.
Every other ranking system can be gamed with quarter squats and bounced reps. FormX can see your reps — so the rank engine caps what strength alone can reach until your form score clears the gate.
Strong but sloppy gets capped. Light but clean climbs honestly. When you see an Obsidian badge on someone’s profile, you know their form held up on camera — that’s what makes the ladder worth climbing.
Same inputs, same rank — the engine is deterministic. No XP grinding, no streak inflation, no paying your way up.
Frank reads your form data
so you don’t have to.
Frank isn't a chatbot bolted on the side — he sees your form scores, your recurring faults, and your rank progress, and he can actually edit your training. Ask why a rank dropped and he'll tell you which rep pattern caused it, then fix Thursday's session for you.
Rank-ups hit different
when your friends see them.
The feed runs on real training moments — rank-ups, PRs, form milestones — not filtered gym selfies. Add friends with a code, react to their lifts, and watch the ladder turn into a group chat rivalry.

“FormX is absolutely amazing! This whole time I thought my form was perfect, but boy was I wrong. I feel the impact so much more whenever I lift.”
“Love what you guys do. Made tracking my sets much easier. 👍”
Quick answers.
How are ranks calculated?
Estimated 1RM from your logged set, normalized by bodyweight and sex, mapped onto strength standards — then capped by your form score.
Can I rank up with ugly reps?
No. That’s the point. Heavy but sloppy caps your tier until your form score clears the gate.
What do I need to film?
Just your phone leaning on a bottle or bench. Front, side, or diagonal angles all work — full body in frame.
Is there a free tier?
Yes — form checks, ranks, and the feed are free to start. Pro removes the weekly limits.
Where does your
squat actually rank?
One form check answers it. Free to start.
