The best digital signing apps for iOS and Android

Increasingly, we are asked to sign forms online, but signing a digital document can get tricky. Digital signature apps bypass the tiresome print-sign-scan cycle of signing digital documents and allow you to quickly and easily put digital pen to digital paper, signing online documents with your name, a preset signature, or whatever scrawl you can manage on your phone, tablet, or laptop touchscreen.

Digital signature apps are great timesavers because any important agreements you get in your inbox can be digitally signed and returned by email. Digital signature apps are not something you use every day, but they do come in handy when the occasion arrives. Whether you keep it on your device all the time or just install it when needed, here are some of the best digital signing apps for iOS and Android.
