Speakfree is an Android App which helps users to make Free Phone Calls without using the Internet. Users get to listen to 10 or 20-second advertisements of products, offers, and services before the call is established. The app needs to be installed only in the caller’s phone, not in the receiver’s. Currently we are offering our service in Kerala, India. At the end of call, users will be prompted with a SMS about the advertisement they just heard.
