Tally

Just move. We count.

Pain: Manual rep counting. Doubt that AI really counts.
Creatives: 3 hooks · 15 s · 9:16
Channels: Meta (Reels), TikTok, YouTube Shorts
We measure: Hook rate · CTR · CPI · ROAS

The client

Workout app that counts reps through the phone camera.

Put the phone down, start moving: Tally sees the body, counts squats, push-ups and lunges, and logs the session. Audience: people aged 20–40 who train at home.

The pain

Manual rep counting. Doubt that AI really counts.

For the business. Fitness ads all promise results. A camera rep counter sounds like a gimmick until people see it work on a real body.

For the user. Losing count mid-set, and not trusting that an app can see what you do.

The solution

Show the proof, not the promise: a live skeleton on the body, joint angles, and the counter ticking up only when a rep really happens.

The skeleton tracks the body, knee and elbow angles appear, the counter rises with each real rep, the session summary, the end card “Try Tally”.
