PiLR EMA Mobile App Features

 

PiLR EMA Product Capabilities

PiLR EMA is a mobile app that is available in Apple iTunes and the Android Playstore. It is written by the same team that built PiLR Health, and is designed with the experience gained from 4 years of custom applications built to meet the needs of researchers. With PiLR EMA and PiLR Health you can:

  • Create deploy a complex mobile app to collect data and render content without programming using our EMA Builder
    • Write your own simple or complex survey
    • Configure rules for translating sensor activity into counts, or activity types (walking, running)
    • Set triggers and conditions for when to present a survey to a participant
  • Run in background and foreground modes. In background mode, PiLR EMA can implement complex rules to determine when to present a study participant with a survey
  • PiLR EMA can access the phone sensors, so it is capable of evaluating rules that use GPS location, activity levels, time and date.
  • Run normally even when there is no network connection. Plus, PiLR EMA caches data and forwards it when a network connection is available (wifi or cellular networks)
  • Gather data from or deliver configurations to bluetooth sensors
  • The mobile app can accept new rules from PiLR Health, so participants’ experiences can change while the study is active
