Not useful – PDF Tools Professional - View, Read, Open, Edit, Export, Annotate, Sign and Fill Form Documents and Contracts Review

Think these are the developers friends writing these reviews. Needed to annotate, can't even highlight. No tutorials, can only add rudimentary text boxes, check boxes, or photos. App keeps crashing as well.
