App Store

Pignus ist eine der iPhone-Applikationen, die gut in Apples frühe „Es gibt für alles eine App“-Werbespots gepasst hätten. Der Download selbst ergänzt das iPhone-Betriebssystem zwar lediglich um ein Feature, in Abhängigkeit von den Anforderungen des Anwenders kann dieses jedoch von großer Bedeutung sein.


Niet zo thuis in de versleuteling van bestanden, maar toch wil je iets beveiligd versturen? Pignus is de oplossing. De app maakt het makkelijk om bestanden met encryptie te delen via iCloud, Dropbox of mail.
