With SmartCall you can easily reduce your phone bill. SmartCall vibrates the phone after a user defined period of time, and you know it’s time to end the call. If the call continues, SmartCall will vibrate the phone again after one minute. SmartCall runs in the background and is completely invisible to the user. Once you have set the call duration and the vibration intensity, you won’t need to touch the settings again. This application will pay for itself in one week. Compatible with S^3 / Anna / Belle Smart Phones.
