Proof of progress your scale can't show
Weight stalls lie. Photos don't. ShotLock turns progress photos from a camera-roll mess into an aligned, private, genuinely motivating record of your journey.
Perfectly aligned, every time
The capture screen overlays your previous photo as a ghost image — line yourself up, shoot, done. Same angle, same framing, every week. That's what makes comparisons honest. You can also import photos from your library and crop them to match.
Compare any two days
Pick a baseline, pick any day, then flip between side-by-side and the reveal slider — drag and watch one photo dissolve into the other. Subtle changes you'd never see in a mirror become obvious.
Your journey as a film
Select the days that tell your story and play them as a smooth timelapse. When you're ready to share, the celebration video mode restyles the screen, counts you down, and records a polished clip — made for the moment your friends ask 'wait, how much?'.
Frequently asked questions
Are my photos uploaded anywhere?
No. Progress photos are stored on your device, in ShotLock's private storage. They're not in your camera roll unless you export them, and they're never uploaded.
Can I import old photos?
Yes — pick any photo from your library and ShotLock's cropper sizes it to the standard frame so it lines up with your captures.
Can I back-date a photo?
Yes, you can assign any photo to any day, and edit it later. One photo per day keeps your timeline clean.
