Check-In: Physique

Check-In: Physique
The most powerful motivation in fitness isn't a program, a coach, or a number on a scale. It's seeing your own body change.
Check-In is a progress photo app built around one thing: showing you how far you've come. Check in consistently, build your streak, and watch your timeline fill with proof of your work, week by week, month by month, phase by phase.

See the difference
The comparison view puts any two check-ins side by side for the same pose. Drag the slider. The work speaks for itself. No estimated body fat charts, no AI analysis, no progress bars. Just your photos, next to each other, showing you exactly what has changed.

Built for the habit
Ghost overlay shows your last check-in as a semi-transparent guide in the camera view before you shoot. Same pose, same angle, every time. Consistent photos make comparisons actually useful.
Streak tracking rewards showing up. Check in on time and it builds. Miss and it resets. Your cadence is now visible and honest.
Anchored reminders count from your actual last check-in, not a fixed weekday. Your schedule stays consistent no matter when you started.
Widgets and Live Activities put your progress and quick entry points on your Home Screen and Lock Screen. Check-In is there when you need it.

Yours alone
Progress photos are personal. Check-In keeps them that way. Your photos are stored on your device and never uploaded to a server. Nobody else sees them unless you choose to share.
