Founder of AppToDesign
Tanmoy Khanra
I run AppToDesign, an app studio in Kolkata, India. I build eSign PDF, the iPhone app for signing PDFs you receive, and I write these guides.
How I test these guides
Tested on iPhone
Every step is done on a real iPhone first. The demo video is a real recording.
Prices checked and dated
Competitor prices come from their own pages, with the date checked.
Real reviews, counted
Complaints come from App Store reviews we counted. No invented quotes.
Honest about limits
Pages say when a free tool or another app is the better choice.
Disclosure: I make eSign PDF ($59.99 once in the US). The guides also say when you don't need it.
