Hughie
Step 1: Your body becomes a skeleton of 33 points
When you start a live session, Hughie runs an on-device pose-detection model against every camera frame. The model finds landmarks — shoulders, elbows, wrists, hips, knees, ankles, and more — roughly 33 points that together form a live skeleton of your body. This runs many times per second, entirely on your phone's processor.
Step 2: Joint angles tell the story of a rep
Each exercise has a geometric signature. A push-up is your elbow angle closing as you descend and opening to lockout while your body stays in line. A squat is your hip and knee angles closing to depth and opening to full standing. A jumping jack is arms and legs cycling between closed and extended. A plank is a held shoulder–hip–ankle line.
The counter is a state machine riding those angles: top position → descending → bottom position → ascending → rep counted. The app confirms it can see you before the countdown, and if you drift out of frame mid-set it prompts you to reposition.
Step 3: Everything stays on your device
This is the part worth being picky about when choosing a rep counter app: where does the video go? In Hughie, nowhere. The camera frames are processed live on-device and discarded — never recorded, never stored, never uploaded. The only data that persists is the output: your reps, sets, duration, and calorie estimates.
Why automatic counting changes behavior, not just logging
Manual logging fails at the exact moment training gets hard: end of a set, out of breath, arms shaking. Automatic counting removes that failure point and adds something a notebook can't — a live number climbing while you move, spoken out loud. Hughie stacks motivation on top: reps earn progress on daily challenges, challenges earn coins, coins unlock accessories for your puppy, and completed sessions keep your weekly streak alive.

AI rep counter FAQ
How accurate is camera rep counting?
Good conditions — full body in frame, decent lighting — make it reliable, but lighting, framing, and camera quality genuinely vary by phone. That's why every set is editable: tap it on the summary and correct the count before saving, and the fix flows into all your stats. If an exercise keeps miscounting on your device, report it in-app (Settings → Contact) — Hughie is built by a solo developer, reports land directly with him, and detector fixes ship fast.
Does it need an internet connection?
Pose detection runs on-device. Your connection is used for account sync and AI coaching features, not for counting reps.
Which exercises does Hughie count?
15 exercises across Beginner, Intermediate, and Advanced tiers — from jumping jacks, squats, planks, side bends, and wall sits up through high knees, split squats, squat jumps, and knee tuck jumps.
