## History

Pinger was founded in 2005[2] by Greg Woock and Joe Sipher.[3] At first, the company created the Pinger Phone in 2008, which consolidated phone, email, and messaging contacts and communications.[2][4] The free texting features were converted into a separate iPhone app called Textfree.[2] Pinger was initially focused exclusively on mobile messaging, but started developing other smartphone apps after Apple released the iPhone software development kit (SDK).[2]
