Already spent half an hour trying to login, even after purchasing a document that can only be open through this device. So bad. ### 3/5 — Lacking features *2023-09-18* I really appreciate the copyright protection the app attempt to do, and I totally support it. The problem is that PDFs lack the search function, bookmark function or any functions that allows you to easily find a term, a topic or something you need to go back to. If these fictions are added, it could be way more powerful. ### 1/5 — Please fix bugs *2019-11-25, version 1.23* I would like to rate this application cause it seems useful and safe but... It crashes every time I try to open a document from my email ... So what now ?... UPDATE . PLEASE UPDATE THIS APPLICATION . I CAN NOT READ MY SCHOOL BOOKS ### 5/5 — Excelente *2017-04-26, version 1.17* Además de ser gratis me ha resultado muy buena es segura ,solo a veces demora un poquito de una foto a la otra tal vez sea mi teléfono ### 1/5 — No funciona *2014-07-08, version 1.9* Hoy instalé esta actualización y temo que cometí un error. La aplicación no abre, y parece que la única solución es desinstalarla y perder todos los archivos que tengo protegidos en mi teléfono. ## Frequently asked questions about Prot ### What types of files can Prot-On encrypt?
