Adobe Systems has made digital signing app EchoSign available, for free, on iOS devices. As well as enabling users to send documents to be signed, the app takes advantage of the touch screens and portability of mobile devices, so legally-binding electronic signing can be done in person.

The service, under the Adobe umbrella since it acquired EchoSign in July, has over 4m users and 50,000 customers worldwide on other platforms.

“The enterprise is experiencing unprecedented adoption of tablets and mobile devices, presenting new opportunities to leverage cloud applications to streamline business processes and greater efficiency,” says Jason Lemkin, vice president of web business services, Adobe and former CEO, EchoSign. “With EchoSign, we’re making it that much easier for organisations to incorporate web contracting into their business models, allowing users to sign documents and send documents for signing right from their iOS device. The end result is a higher rate of contract completion in less time, leading to increased productivity.”
