Built for modern digital research
From EMA and ESM to clinical monitoring and market insights, SMAAT connects your study design with participants’ smartphones and sensors.
Dynamic sampling with item library
Configure time-based, random, and event-based prompts, set quiet hours, and build surveys from a validated item library tagged by construct, so you can drag-and-drop pre-phrased questions instead of writing everything from scratch.
Real-time compliance monitoring
Monitor per-participant response rates by day, week, and survey type in a dedicated compliance dashboard, and receive automated email digests when adherence drops below your thresholds.
Participant engagement & gamification
Keep participants engaged with points, streaks, badges, progress bars, levels, missions, leaderboards, team goals, and optional narrative modes that make intensive protocols easier to stick with.
For researchers, clinicians, and applied teams
Academic & clinical research
Design EMA/ESM protocols, longitudinal cohorts, and intervention studies with fine-grained control over scheduling and measures.
Businesses & market insights
Understand customer journeys, employee well-being, or realtime feedback using mobile surveys and optional passive data.
Healthcare & individuals
Monitor symptoms, routines, and mobility patterns to support digital health interventions and personal self-tracking.
From study idea to encrypted dataset
Design your study
Define surveys, sensor streams, sampling schedule, and inclusion criteria in the web dashboard.
Enroll participants
Share study codes or links, let participants install the SMAAT app, and start receiving smartphone-based data.
Analyze and export
Track adherence dashboards, inspect time series, and export clean datasets for statistical analysis.
Start from a validated study design
Choose from ready-made templates spanning mental health, cognition, sleep, mobility, and more — with surveys, schedules, and sensor configurations already set up.
Use any template as a starting point and customize it to fit your protocol
Sign up to access all templates, clone them into your dashboard, and adapt surveys, schedules, and sensor configurations to your study.
SMAAT app for iOS and Android
Participants join your study through the SMAAT mobile app, available globally and translated into multiple languages to support cross-country research.
Global accessibility
SMAAT supports multiple interface languages so you can recruit diverse samples across regions.
