Everything the platform can capture and measure
An all-in-one platform to survey, schedule, notify, and pay participants — the full ExpiWell capability catalog, in one place.
One platform for modern research
Rich, multi-modal data in real-world contexts — from surveys to sensors to place. The full catalog below sits underneath these six.
Adaptive mobile surveys
Capture thoughts, feelings, and behaviors as they happen — branching logic, twenty question types, and scheduling that bends to the protocol rather than the other way round.
Wearable & sensor data
Objective context for every self-report: activity, sleep, and movement from phone sensors, Apple Watch, and Fitbit, landing in the same export as the answers.
Geofenced triggers
Geographically explicit EMA — a survey fires the moment a participant arrives at, stays in, or leaves a place, so context is captured on site.
Real-time analytics
Catch compliance dips while there is still time to act on them: watch response rates live, then filter and export every stream from one dashboard.
Cross-platform
Meet participants on the phones they already own — native iOS and Android apps, one consistent journey, no app for your team to build or ship.
What surrounds the answer
Place, time, and connection decide what a moment actually means. These seven shape what lands beside every response — and what leaves with you at the end.
Place-based triggers
Geographically explicit EMA: a survey fires the moment a participant arrives at, stays in, or leaves a place — clinic, campus, or community.
GPS capture
Record where an experience happened — with explicit participant opt-in and per-study permission controls.
Adaptive time zones
A 9am survey fires at 9am local, and re-anchors automatically when a participant travels mid-project.
Offline capture
Surveys open and save with no connection, then sync when one returns — fieldwork that doesn’t depend on coverage.
External survey links
The Dynamic Link question type carries participant ID and session data into Qualtrics, SurveyMonkey, or any external URL as embedded data.
Automatic transcription
Voice and video answers transcribed automatically — digital ethnography without the transcription budget.
Structured exports
Everything you captured leaves in one file — surveys, sensors, and timestamps in CSV, TSV, or XML, every row linked by the same anonymous identifier, ready for multilevel models.
60+ capabilities, grouped by what you’re doing

Automatic Transcription
Voice and video answers transcribed automatically on Premium and above — ready to code or analyze.
Multiple study and survey options
Sophisticated designs — screeners, logic, and personalization — with no coding required.
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.
Randomize Questions
Randomize the ordering of questions each time the participant takes the survey.
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.
Easy survey scheduling
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.
Geofenced Triggers
Fire a survey on arrival at, stay in, or departure from a location — clinic, campus, or community. Geographically explicit EMA, on the GEMA plan.
Multiple question types
From single selection to multimedia capture and cognitive tests — tailor every prompt to your objectives.
Convenient project distribution
Access Code
Participants enter a unique access code into the mobile app to start the project.
Invite by Email
Only participants with specific email addresses can start the project — great alongside existing data-collection platforms.
Temporary User Accounts
Project-based temporary accounts for fully anonymous collection — very useful for populations who can’t easily create their own account.
Response data you can act on
Data Download
Download response data in CSV, TSV, or XML, numeric or choice text — all surveys linked by a unique anonymous identifier.
Time-Stamped
Survey completions are time-stamped for tracking when participants complete them.
