### 2/5 — Pretty sure this is AI slop

*2026-08-10*

It’s paid once you get into the app, but there is a 3 question preview that shows incorrect diagrams, mentions equations not even found in the PE handbook, and the reference for the solutions is too vague to be remotely helpful. Stay away.

**Developer response:** Thanks for the helpful feedback! You're right about the references. Most solutions cite the handbook but don't define the section. We're currently fixing these so that each one references the applicable section, or indicates where a method isn't in the handbook at all.

On the diagrams, I rechecked every figure in the preview against its problem data and the numbers line up, so I'm not sure which one you mean. Everyone who previews an exam gets the same three problems. If you email support@ingenioproductions.com with the exam name, I can pull up the exact figure you saw and fix it. And if you did buy an exam and it isn't working for you, email us and we'll help you get a refund from Apple.
