Bella bella

Funziona bene. Bravi! La 5 stella se l'aggiornate con la possibilità di seguire i link anche iPhone e iPad creati con PDFpenPRO su Mac.

Non buttate soldi applicazione pessima

L'ho acquistata per annotare sui PDF con la penna Adonit Jot Script ed usufruire del palm rejection. Ma non fa il suo dovere: il testo viene sottolineato dal mio palmo e non dalla punta della penna.

Inoltre il sync reclamizzato funziona solo con dropbox e icloud. Per quanto riguarda il WebDAV è un semplice importa/esporta a mano (niente a che vedere con i sistemi di sync avanzati come in iAnnotatePDF o GoodReader)

Ripeto l'unico motivo per cui avevo investito questi 17,99€ era per avere la compatibilità con la Jot Script. Per cui soldi buttati

Soldi buttati

Firmare documenti? La scrittura è talmente imprecisa da sembrare quella di un bambino di prima elementare. Questa app non mantiene quello che promette. Non c'è nemmeno la gomma per cancellare gli errori di scrittura. E io l'ho presa per firmare i documenti. Bell'affare. 1000 volte meglio la app Iannotate che costa tre volte di meno. Ladri.
