Pinger has been building apps that help people communicate in new and surprisingly simple ways since 2005. Our two flagship services, Sideline and Textfree, have been used by over 100 million people around the world. Sideline gives people a 2nd phone number to organize work and life on one device. As the go-to phone solution for mobile professionals, Sideline is one of the fastest-growing communication apps in the App Store and Google Play. Textfree makes communication free and accessible, even without a carrier plan. As the original free texting app, Textfree lets anyone with an internet connection call and text for free from a real phone number.
