I started out using HomeReport from AHIT on my iPad. It's ok, but I discovered that I can use it on my iPhone 6 Plus last week. With a larger phone, I can now navigate around the app and take pictures immediately without the clunkiness of a large tablet in the attic or crawlspace. Major drawback is that is goes on a crashing binge from time to time. I do like that I can customize it fairly easily and it's already paid for with my previous license. AHIT has a new software piece called InspectIT, but it has a monthly license and works only on tablets.
