Photo Proof Before You Drive Off the Rental Lot

The idea

Every time I rent a car I forget to photograph every scratch and dent before driving away, and then I get hit with a damage charge weeks later for something I didn't do. I want a quick guided walkaround, maybe just a laminated checklist taped to the counter or a simple app, that times-tamps and geotags photos of all four sides, the wheels, and the interior in under two minutes. Store those photos somewhere I can pull them up fast if the rental company disputes it later.
