Pose-guided, hands-free capture and ghost-overlay alignment mean every shot lines up — so your check-ins stay consistent and you have time to hit the pose just right.

CAPTURE THE RIGHT WAY • Guided sessions walk you through your division's mandatory poses • Hands‑free: start each pose by voice ("let's go" — or your own catch phrase), motion‑stillness, or a timer • Ghost overlay of your last shot so you match framing every time • Burst Mode takes multiple shots of each pose (optional) SEE YOUR PROGRESS • Side‑by‑side and blended overlay comparisons • Auto‑align two photos; isolate yourself onto a clean background (on‑device) • Export timelapse animations to show your prep over time TRACK THE NUMBERS • Log weight and measurements; see trends and weekly change • Goal countdown with prep progress • Multi‑show career: organize check‑ins by show and compare across years PRIVACY FIRST: YOUR DATA STAYS YOURS • 100% on-device — your check-ins are never uploaded to our servers • No account, no sign-up.
