Backup Email Notifications
Sending email backup reminders to participants who may not have immediate push notifications for time-sensitive projects
Real-time data dashboard
Obtain real-time information on the number of participants and time taken for each survey within the project.
Participant logs
Track individual participant response rates in real-time for different surveys and view specific responses. Able to view response rates based on expected responses to date or expected responses for the entire project. Track notification status to know whether participants are receiving push notifications.
Participant payments
Compensate participants directly with Amazon gift cards without the need for any identifying information. Compensation can be based on response rates seen in participant logs. Great for keeping projects anonymized while paying participants.
Screen participants by creating project requirements (e.g., demographics, location). Great for online recruitment of participants.
Rolling Schedule
Prevent participants from continuing based on random responding or careless responding to improve data quality.
Static (Event-based) Schedule
Surveys can be taken whenever the participant chooses.
Combine Schedules
The easy-to-use scheduling interface allows combining schedules for different types surveys (e.g., event-based survey and random survey). In ESM and EMA terminology, you can create schedules for event-contingent, signal-contingent, and interval-contingent protocols all in a single project.
Set Start & Close Times
Control when participants can take surveys so they cannot backfill surveys outside the scheduled time
Randomized Survey & Notification Times
Create randomized times for participants taking the survey. E.g., survey will be randomly available for 1 hour between 8-11 am.
Fixed interval Or Snoozed Reminders
Remind participants to complete an available survey when they have not done so after a certain time.
Personalized Schedule
Enable participants to change when the timings of the surveys on the mobile app. Great for shift and healthcare workers who may have different schedules.
Event-triggering
Create contingent surveys and notifications based on participant responses. Great for adaptive interventions, ecological momentary interventions, and just-in-time-adaptive interventions (JITAI).
Adaptive Time Zone
All schedules are automatically adapted to participant time zones. A 9 am survey will occur at 9 am regardless of which time zone a participant is in. If they change time zones halfway through the project, the mobile app will adapt the schedule accordingly. Great for recruitment of participants around the world or for participants that frequently travel.
Researcher-enabled Push Notifications
Send customizable push notifications to participants from the participant log to send friendly reminders and increase participation rates.
Choose one option among multiple options. E.g., “strongly agree” to “strongly disagree”.
Multiple Selection
Choose one or more options with checkboxes.
Dropdown Selection
Choose a single option from a dropdown list.
Rating Scale
Provide ratings based on the number of stars. Researchers decide on the maximum number of stars.
Counter Question
A counter to count the number of occurrences of one or more events happening. Useful in clinical or health settings to count the number of occurences or behaviors.
Scale Question
Slider question where a response is made on a scale decided by researchers. E.g., sad to happy
Matrix Question
Multiple questions that have the same response format.
Grid Question
Select a cell on a two-dimensional grid that best represents the experience. E.g., affect grid with a horizontal axis sad-to-happy and a vertical axis low-to-high arousal.
Text Input
Enter free-form text
Numeric Input
