Muito triste isso. Todos os meus estudos e anotações nos livros e artigos foram perdidos. ### 4/5 — Crashing *2026-03-05, version 8.1.0* 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? ### 1/5 — Stopped working having not long renewed subscription *2026-01-30, version 8.1.0* App now crashes every time I go to create a PDF or try saving a current one. Have tried the fixes google recommends but none work and no support available on website. ### 3/5 — bom mas o kybook 3 é melhor *2024-01-09* alem de caro o app tem alguns problemas, então acabei optando pelo kybook 3 ### 1/5 — Great app when works *2023-09-06, version 8.1.0* I purchased the pro app but for some reason does not transfer all documents from the basic version. ### 1/5 — cannot download pdf max any longer *2023-04-19, version 4.1.0* PDF Max stopped working on my mac - macbook pro M2. I deleted from the macbook and tried to download but it will no longer download. Check its fixed before paying as if it doesnt work its a waste of money. ### 1/5 — bad *2023-04-18, version 4.1.0* literaly didnt let me add my pdf or do anything without paying for the premium - maybe its just stupid design or maybe its the fact its so hard to understand but dont be fooled by the 1 review that gave it 5 stars ### 5/5 — Sharon *2022-12-10, version 8.1.0* LOVE THIS APP! I finally have an easy way to save things in an organized way on my IPad. Could not be happier. ### 1/5 — Crashes at opening *2022-08-19, version 8.0.1* I have PDF Max and Max Pro for my iPad and both crash every time I open them. What the heck?!!? It used to work perfectly. Now… useless. ### 1/5 — Need a subscription to do text! *2022-05-25, version 4.0.1* Looked useful, but needs a subscription to do even the simplest of things. Very dissapointing. ## Frequently asked questions about PDF Max ### What can I do with PDF Max? PDF Max allows you to read, annotate, and sign PDF documents on your iPhone and iPad.
