Ecological momentary assessment
Measure experience as it happens.
Build EMA, experience sampling, and diary studies without writing an app. Participants answer short check-ins on their phones, and you export tidy data for R or Python.

Build the protocol you designed
Choose when each check-in can happen, and mix schedules in one study. Every random schedule is saved, so you can see exactly when each prompt was planned.
Fixed times
The same times each day, such as 8 AM and 8 PM.
Random times
A set number of prompts in a window, with a minimum gap between them.
One per window
One random prompt in each window you define: morning, midday, afternoon, evening.
When it happens
Participants start a check-in themselves after an event, such as a craving, a headache, or a meal.
Easy for participants
Participants use the phone they already carry. Check-ins are designed to be short.
Join with a QR code or link
No app store. Participants open a link, agree to the consent, and add the app to their home screen.
Reminders on their phone
Push notifications and email, with quiet hours and one follow-up reminder.
Works offline
Answers save on the phone and sync when it reconnects.
One question per screen
Large buttons and a progress bar, sized for a quick check-in.
Data you can trust
Timing, missed prompts, and protocol changes are part of the research record, so they are kept with every answer.
Every check-in keeps its timeline
When it was scheduled, sent, opened, started, and finished, in the participant's time zone.
Protocol versions
Change a live study without overwriting what came before. Each answer records the version it used.
Exports for analysis
Long and wide CSV files, a reminder log, adherence by participant, and a data dictionary.
Pilot first
Test the study with your team. Pilot data stays out of your results.
Planned
More than surveys
Add a speech sample, a cognitive task, a video task, or a sensor reading to the same check-in. ConductSpeech, ConductCognition, ConductVision, and ConductSignal do the measuring, and every result lands on one timeline per participant.
Clear prices
Free for pilots and teaching. The Researcher plan is $399 a year and the Lab plan is $1,199 a year. Questions, check-ins, and responses are unlimited on paid plans.
