It Simply Doesn’t Work!

Even with the paid version, the app cannot edit the original text in a PDF. It only allows you to “fill in” the document by adding text boxes, which even use a different font from the original. The native iOS app already does that.

I purchased this app specifically because I wanted to literally EDIT PDFs by modifying the existing text within the document itself, not simply adding text boxes on top of it.

Waste of money

Any major adjustments.. forget it. You have to pay more utilizing a subscription plan. Not worth it!!!! Big ripoff!

Paguei e o app ainda pede mais dinheiro para continuar tirando marca d’água

Assinei o app para tirar marca d’água de fotos, eis que me deparo com ele pedindo mais dinheiro dizendo que meus créditos acabaram. Absurdo!
