Project Screener
Screen participants by creating project requirements (e.g., demographics, location). Great for online recruitment.
Screener Questions
Prevent participants from continuing based on random or careless responding to improve data quality.
Branching & Logic
Create sophisticated surveys with branching and logic — ideal for personalized surveys or interventions.
Piping
Create question text based on previous participant choices to further personalize surveys.

Automatic Next Question
Move participants to the next question immediately after a choice is made — a great time saver on long surveys.
Forced Choice
Require an answer before moving to the next question — excellent for important questions.
Request Response
Request an answer when participants skip a question. Great for gently reminding participants.
Mobile Charts
Give participants viewable charts to track their own responses and growth over the project.
Hide Progress Bar
Option to hide the progress bar for long surveys.

Event-contingent, signal-contingent, and interval-contingent protocols — combined in a single project.
Calendar Schedule
Send surveys on specific dates — e.g., ask every participant about New Year’s resolutions beginning January 1.
Rolling Schedule
Collect a set window of data — say two weeks — from each participant regardless of when they start the project.
Static (Event-Based) Schedule
Surveys can be taken whenever the participant chooses.
Combine Schedules
Combine schedules for different survey types — event-contingent, signal-contingent, and interval-contingent protocols in one project.
Start & Close Times
Control when participants can take surveys so they cannot backfill outside the scheduled time.
Randomized Survey & Notification Times
Create randomized timings — e.g., a survey randomly available for one hour between 8–11 am.
Fixed or Snoozed Reminders
Remind participants to complete an available survey when they have not done so after a certain time.
Personalized Schedule
Let participants adjust survey timings in the app — great for shift and healthcare workers.
Event-Triggering
Trigger contingent surveys and notifications based on responses — built for adaptive interventions, EMIs, and JITAIs.
Adaptive Time Zone
Schedules adapt automatically to each participant’s time zone — a 9 am survey fires at 9 am local, even when participants travel mid-project.
Researcher Push Notifications
Send customizable push notifications from the participant log to send friendly reminders and increase participation rates.
Multiple question types
From single selection to multimedia capture and cognitive tests — tailor every prompt to your objectives.
