This is a really smart feature request, photo-based documentation would save so much time on job sites, especially when your hands are full with tools and meters. Being able to overlay measurement data directly onto a picture and generate a clean report for your boss would be a game changer. On a slightly different note, since you’re into efficient documentation and organizing visual info, I recently came across a site where you can visit products section to see how beautifully they present handcrafted glass items with clear specs and images, it’s a great example of combining visuals with useful data, similar to what you’re describing for measurement logging. Hope your idea gets traction; phase three with graphs would be awesome too.
