Mobile EMA


ilumivu’s mobile ecological momentary assessment app – mEMA – enables researchers to collect real-time data from participants as they go about their daily life. It is used by researchers using Ecological Momentary Assessment, Experience Sampling methods and ambulatory assessment.

Our native Apple and Android apps allow participants to use their own phones increasing compliance and reducing burden. mEMA sends in-app push notifications so your study keeps running even when the phone is offline. mEMA also runs response time tests with millisecond precision collects data from in-phone sensors, and can integrate with wearables.
