Easy M


Easy M was an Android smartphone app for researchers and clinicians to conduct experience sampling studies that collect behavioral data from sensors. Its goal was to make smartphone-based experience sampling studies easy, simple, and fun. I built and maintained Easy M between 2013-2017, and supported the studies listed below.

Smartphone Surveys with Configurable Notifications

Ask your participants to assess their mood, health, and context with a variety of questions using Easy M's reconfigurable interfaces, ranging from categorical to Likert scales. Prompt your participants to answer a survey at specific times of the day, or let the device pick random times to beep.

Behavioral data from Sensors

Study your participant's mobility, sociability, and physical activity by capturing data passively from their smartphones' sensors. Use machine learning algorithms to analyse participants' daily behaviours, such as meaningful places and dynamic communication networks.
