Strength, with your crew.

Forge is social strength training. Set up your phone and lift: on-device camera rep counting that never sends a frame off your phone, an AI form band with the exact cues to fix, programs that adapt to what you actually lifted, and a crew that cheers, not judges.

The honest limits

What it does, and what it doesn’t

a band and a cue · never a verdict on your body

What it does

  • Counts reps on-device from your movement — free and unlimited
  • Returns one form band plus the single biggest cue to fix
  • Builds a program that adapts to what you actually lifted
  • Shares sets with friends and challenges — all opt-in

What it doesn’t

  • Never sends camera frames off your phone for rep counting
  • Never invents a rep or a fault it can't see — it pauses and asks
  • Isn't a safety rating, injury screen, or medical assessment
Not medical advice. Talk to your clinician.
How it works

Four things, done properly

Your camera counts the reps

Prop your phone up and lift — Forge counts reps from your movement, on-device, free and unlimited. Counts may be imperfect, so every set is one tap to correct.

The one thing to fix

Upload a set video and Forge returns a band plus specific cues drawn from your own footage — depth, tempo, side-view joint angles. No vague “keep your core tight.”

Programs that adapt to you

Forge builds a strength program around your goal and equipment, then adapts it to what you actually lifted — and tells you why next session looks the way it does.

A crew, not a feed war

Friends, challenges and leaderboards — opt-in and dismissible. Cheer PRs, take on a challenge together. No streak guilt, no shame mechanics.

Questions

Straight answers

How accurate is camera rep counting?

Counting runs entirely on your iPhone, and real-world conditions — angle, lighting, how much of you is in frame — affect it. Counts may be imperfect, and every count is one tap to correct. When Forge can’t see enough, it pauses instead of guessing.

Does the rep counter send video anywhere?

No. Rep counting is processed on your device — camera frames never leave your phone. The only videos that reach our servers are set videos you deliberately upload for a form check, deleted automatically within 48 hours.

What do form-check bands mean?

A band summarizes how the set looked, plus cues tied to what a single camera view can measure: depth, tempo, side-view joint angles. It’s technique information, not a safety rating.

Forge counts and coaches for fitness, not medical assessment. Rep counts, bands and cues are estimates and technique information — not diagnosis or treatment. Consult a qualified professional before starting any training program, and stop if something hurts.
