Learned this the expensive way, sharing so you don't.

Had a tenant move out and try to claim a bunch of damage was there before they moved in. I had taken move-in photos — but they were just regular phone pics. The tenant argued they could've been edited, or taken any old time. With no way to prove they were real and untouched, they were basically useless in the dispute.

Now I document every move-in and move-out with a tool that seals each photo — proof it was shot live on the spot, not filtered, edited, or pulled from the camera roll, and locked to the exact date and time. So nobody can argue the photo's been doctored or that I took it whenever it suited me.

Happy to drop the (free) tool in the comments if anyone wants it — don't want to spam. Main point: a regular photo proves almost nothing in a dispute. It has to be provably real and dated.
