There are many good ones, but not all run on Apple products. This question comes up all the time, and the main answer you’ll get is basically: “Whichever one works best for you, use them all with the free trials, and decide from there”. I agree with that statement.
To answer your question about opinions, I used AHIT’s Inspect It or whatever it’s called, and really didn’t like it. Didn’t use it very long, and moved to Home Inspector Pro, and love it. There is a desktop version, that you have to use to generate your report. HIP mobile is their mobile version, which I love as well. You have to pay a cloud service to upload from the mobile so you generate report form desktop version.
It is a really nice set up, and I started out using the iPad for mobile and my Mac desktop for the desktop version. The iPad was too big and bulky for me, so I’ve been using my iPhone. I like that much better, but it’s a bit small, and my phone is giving me issues, so I have to go to the store and deal with that, so I’ll probably end up wit a new phone, and do it that way. If not probably get an iPad mini, or a different tablet. Good luck to you.
