iPhone
Your roommate says they didn't touch anything. Prove them wrong.
TamperCheck is a change detection camera. Take a photo of your desk, your shelf, your drawer — whatever you want to keep tabs on. Come back later and take another photo. The app figures out what's different.
It doesn't just overlay two images and hope you spot something. It actually aligns them first, correcting for the fact that you're never standing in exactly the same spot twice.
HOW IT WORKS
1. Take a reference photo of your space
2. Come back later and take a comparison photo
3. The app aligns the images and finds what changed
4. Changed areas show up highlighted in red
SMART ALIGNMENT
Here's the problem with other "spot the difference" apps: they need you to hold your phone in the exact same position both times. That's nearly impossible in practice.
TamperCheck uses the same feature-matching algorithm used in professional image analysis to find common points between your two photos, then mathematically warps one image to match the other's perspective. You can be standing a foot to the left, at a different angle, and it still works.
WHAT THE DETECTION ACTUALLY DOES
The comparison goes deeper than just checking if pixels changed color:
• It diffs each color channel independently. If someone swapped a red book for a blue one at the same brightness, grayscale comparison misses that. This doesn't.
• It adapts to uneven lighting. A lamp in one corner doesn't throw off the whole analysis.
• It runs the check at two different scales and only keeps detections that show up in both. Cuts out noise.
• It uses structural similarity (SSIM) to ignore cases where the lighting shifted but nothing actually moved.
Three sensitivity levels let you tune it. Low catches big stuff like moved furniture. High catches a drawer left slightly open.
YOUR PHOTOS STAY ON YOUR PHONE
There's no account to create. There's no cloud upload. There's no server on our end receiving your images.
All image processing happens on your device. We built it that way on purpose. We literally cannot see your photos.
WHO THIS IS FOR
• Shared apartments. Yes, your roommate did open that drawer.
• Your desk at work. Did someone go through your papers while you were at lunch?
• Hotel stays. Take a photo of the room when you check in, check it when you get back.
• Packed luggage. Take a photo before the flight, check it after.
• Insurance documentation. Before-and-after records of property condition.
• Storage units. Periodic checks that nothing's been disturbed.
