Our Mission

We lead the science of Ecological Momentary Assessment — what people do, feel, and think in everyday life — and make the research tools to study it accessible to every researcher.

One platform for experience-centered data, real-time communication, and community — built where scientific rigor meets human-centered design, so researchers and participants alike love using it.
