The old way: receive PDF → print → sign with pen → scan → email back. The phone way: receive PDF → sign with finger → send back. Takes 30 seconds instead of 30 minutes.

Tips for Better Signatures
Use your finger, not a stylus — finger signatures look more natural on touchscreens. Sign slowly for smoother lines. Landscape mode gives you more space to draw.
