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.
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.
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.
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.”
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.
Friends, challenges and leaderboards — opt-in and dismissible. Cheer PRs, take on a challenge together. No streak guilt, no shame mechanics.
| Record | What it is | Where |
|---|---|---|
| Reps counted | Set count you can edit | On your iPhone |
| Logged sets & PRs | Weight, reps, history | On your iPhone |
| Form-check video | Only a set you choose to upload | Encrypted, auto-deleted within 48h |
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.
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.
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.
