Pebble uses data science and analytics to improve its smartwatch products. Pebble's data team analyzes over 60 million records per day from the watches to measure user engagement, identify issues, and inform new product design. Their first problem was setting an engagement threshold using the accelerometer. Rapid testing of different thresholds against "backlight data" validated the optimal threshold. Pebble has since solved many problems using their analytics infrastructure at Treasure Data to query, explore, and gain insights from massive user data in real-time.
