Funciona genial. ### 1/5 — Incidencia *2021-02-05, version 4.0.1* No me funciono. Espero que no sea fraudulenta. ### 5/5 — Gran aplicación, con un margen de mejora *2020-03-03, version 4.0.1* Excelente app para firmar tus documentos de manera digital con certificado electrónico. La única que deja hacerlo al ciudadano, sin tener que pasar por laboriosos registros para darte de alta. Simple y eficaz.

Visualización de la firma en formato texto, p.ej. Documento firmado digitalmente por... ### 1/5 — No funciona *2019-01-13, version 4.0.1* Por lo que sea ha dejado de funcionar. Que lastima ya que merecía la pena ### 1/5 — No funciona *2019-01-11, version 4.0.1* Parece interesante y sencilla pero no funciona ni con el certificado demo que ellos incluyen. ### 1/5 — Ha dejado de funcionar *2017-07-28, version 1.9.0* Con este programa se podía firmar con firma digital oficial cualquier documento PDF. Esta aplicación era muy útil, entre otros, para abogados y procuradores que quisieran firmar documentos para presentar en organismos públicos desde un IPad. Es una pena que haya dejado de funcionar, si pudieran arreglarlo se lo agradecería. Ya no permite firmar con firma digital ningún documento, da un error genérico incomprensible. Gracias. ### 1/5 — Doesn't work. *2014-10-22* Went through all the steps to get the document I need signed on the app and the app never showed up. Glad it was free and easy to delete. ### 1/5 — absurdo *2014-08-30, version 1.8.0* He modificado un documento firmado, al verificar el documento manipulado indica que la firma es correcta y no indica que, en cambio, el PDF ha cambiado ¿de qué sirve entonces? ## Frequently asked questions about Mobile Signer ### What document formats can Mobile Signer sign?
