Body Tracker — your transformation, in pictures.

Track your body transformation week after week with guided progress photos, before/after comparisons and complete body tracking. Whether your goal is weight loss or building muscle, Body Tracker makes your progress visible and keeps you motivated.

Guided progress photos
Retake every photo from the same angle thanks to a ghost overlay of your previous shot and a tilt guide. Your pictures stay perfectly aligned for honest, reliable comparisons.

Before / after
Compare two photos side by side or with a sliding slider. See your evolution over 30, 90 or 365 days and measure how far you've come.

Weight & measurements tracking
Log your weight with each photo, follow the trend line and spot your progress. Add notes and muscle-group tags to every entry.

Streaks & consistency
Keep the momentum going with streaks, consistency dots and milestones. Personalized reminders help you never miss a photo.

AI Visual Check-in (premium)
Get a kind estimate of your body composition and posture from a single photo, with concrete tips. Reserved for users aged 18+, with your explicit consent.

Private by default
Your photos, weight and measurements stay on your device — no account required. The only time a photo leaves your phone is the optional Visual Check-in, and only when you explicitly ask for it.
