User Reviews

Reviews show PDF Max is valued for organization and iOS integration, and for document review capabilities. However, crashes, data loss after updates, and a subscription-centric pricing model drive significant dissatisfaction. Additional frustration stems from restoring purchases and the removal/gating of features like merge. Overall, strong organization and compatibility are noted positives, but stability and pricing changes are the primary concerns.
Pros
  • Easy to save and organize PDFs on iPad/iPhone.
  • Integrates well with iOS apps, making PDF access quick and convenient.
  • Useful for reviewing plans and checking Building Codes.
  • Longstanding app with extensive document storage and history of use.
Cons
  • Frequent crashes or instability when annotating, saving, or opening PDFs.
  • Features locked behind subscription or pro plans, reducing value of one-time purchases.
  • Data loss or inaccessible files after updates or crashes (lost work).
  • Difficulties restoring prior in-app purchases and generally poor customer support.
  • Removal or gating of key features (e.g., merge, form flattening, text reflow) or requiring extra fees after updates.

I have always enjoyed this app. However, I just downloaded the latest version on my new iPhone 13, which has the latest iOS on it. And PDF Max keeps crashing every time I try to annotate a page. I never had that problem with the older version on any device! What can be done to fix this problem?

I purchased the pro app but for some reason does not transfer all documents from the basic version.

LOVE THIS APP! I finally have an easy way to save things in an organized way on my IPad. Could not be happier.
