PebbleFit is an app and pedometer system that uses Pebble smartwatches and Android tablets to encourage physical activity among middle school students. It allows students to form groups and compete socially by tracking steps and viewing rankings. The free system integrates the Pebble watch and Android tablets, allowing for motivation through social competition not found in other fitness apps or devices. Developing the project taught the student team about software development, project organization, and effective team communication.
