schema is an app-making toolkit for iOS and Android for designing, developing, and deploying mobile apps for health assessment and intervention. There are three key benefits to the schema platform:
Build your study using a single protocol file - no coding required.
All survey items and data collected are stored on your own server, independent of the schema platform.
schema is free to both researchers and participants for non-commercial use.
A wide range of elements are included to build research tools and clinical interventions, including: audio, video, slider, date/time picker, checkboxes, radio buttons, text, and more. Most elements also support dynamic branching.
Multiple instruments can be deployed in a single study/intervention, allowing for flexibility of study design (e.g. pre and post surveys, incremental release of surveys, and so on).
Flexible scheduling of alerts, including once-off alerts, recurring alerts, open responses, location-based alerts, and more, meaning the platform is suitable for ecological momentary assessment, longitudinal research, interventions, observational studies and data collection in the field.
Any outcome variable can be easily linked to a dynamic feedback graph to allow your users to track their progress or behavioural change over time. Interval data types are currently supported.
