Free Basic version
Every ExpiWell account starts on the Free Basic plan — free forever, no credit card required. It enables event-contingent Experience Sampling Method (ESM) and Ecological Momentary Assessment (EMA) research with no restrictions on scale, and creating an account takes about a minute.
What Free Basic includes
- Unlimited participants, responses, and projects
- Unlimited mobile surveys, with event-contingent ESM and EMA
- 12 question types, with randomization, grouping, and skip logic
- Rich text capability
- In-app digital payments (20% transaction fee)
- Free native iOS and Android apps for participants, in thirteen languages
- Participants automatically link across surveys and projects
- Anonymous tracking of participants' response rates and engagement
- Data export via CSV, TSV, or XML
Creating your free account
- Click Create an account anywhere on expiwell.com.
- Check your data region before you continue. Signing up creates a Global account, which stores your data in the United States. If your organization is based in the EU or EEA, follow the EU link on the sign-up form instead — the EU is a separate platform, not an option on this one.
- Set up your first project and build a survey with the no-code builder.
- Invite participants — they join through the free ExpiWell app.
Your region is fixed at sign-up and cannot be changed from the account afterwards — moving requires a support request and a data migration. There is no region selector to switch later, so take the EU link before you continue if that is where your organization is based.
When you need more
Scheduled notifications, adaptive time zones, multimedia collection, event-triggering, wearable integrations, and geographically explicit EMA live on the paid plans — Plus, Premium, Sensor+, and GEMA — each of which can be trialled free for 7 days when you sign up. See Try a free EMA & ESM subscription or the subscription page for the full comparison. Graduate-student, short-term, and academic-department pricing are available.
