One platform, from design to data.

Your whole study, live.

Centralive integrates everything a digital health study needs: wearables, questionnaires and EMAs, a drag-and-drop Participant App and just-in-time adaptive interventions that close the loop.

Built at the UC Irvine Institute for Future Health NSF-supported
Centralive sits between participants and the research team. Wearable data and questionnaire and EMA responses flow into Centralive, which updates each participant's Dynamic Profile and delivers just-in-time adaptive interventions (JITAI) to the Participant App. The team sees adherence, reminders and secure exports in the Researcher Dashboard.

How it works

Design, collect, monitor, decide, intervene, optimize.

One connected workflow, from protocol to analysis-ready data.

  1. DesignBuild questionnaires, EMAs, schedules, reminders, the Participant App and its rules, with micro-randomization built in.
  2. CollectWearable data, smartphone sensing, questionnaire answers and EMAs arrive in one timeline.
  3. MonitorTrack adherence, act on alerts and export data for analysis.
  4. DecideRules check each participant at the decision points you set.
  5. InterveneNudges, questionnaires, EMAs, content or a Livi conversation reach the participant.
  6. OptimizeOutcomes from every decision show which interventions work, so you refine the pool and rules as the study runs.
App Designer

Build your own Participant App with drag and drop.

One native iOS and Android app runs every study, designed by the people who wrote the protocol.

Just-in-time adaptive interventions (JITAI)

From state to outcome, at every decision point.

A closed loop: data comes in, the right intervention goes out, and every decision is measured.

Feedback channel: new readings, questionnaire and EMA responses & adherence return to the sources

Rule-based

IF/THEN decisions personalized from each participant’s Dynamic Profile, with a full decision log.

Advanced designs

Micro-randomized trials (MRTs), timing optimization and burden caps for intervention research.

Why teams switch

Replace the patchwork.

TodayWith Centralive
A survey tool, separate case report forms, wearable exports, reminder scripts and spreadsheetsQuestionnaires, EMAs, case report forms, devices, reminders and data in one place
One fixed intervention for every participant, decided before the study startsA pool of interventions, matched to each participant's data and optimized as the study runs
A custom app costs far more and takes months to build, or a fixed layout you can't changeYour own Participant App, built with drag and drop in minutes

Dynamic Profile

Personalized to every participant.

Each participant’s Dynamic Profile keeps their live context in one place. It updates as wearable, questionnaire and EMA data arrive, so your rules and interventions adapt to the person.

Live participant context

Each participant's current data, in one place.

Updates from data

Values refresh as wearable, questionnaire and EMA data arrive.

Group participants

Group participants by what their data shows.

Rules without code

Use profile values in JITAI rules and personalize thresholds.

Livi AI Agents

Livi: AI agents for digital interventions.

Centralive connects with Livi so your interventions can be a two-way conversation, not only a pushed message. Livi agents are built from your own guidelines, connected to your study’s data, and governed by your rules.

Pain assessment
Centralive gave me direct access to raw wearable sensor data, which significantly accelerated my pain assessment studies and opened up new possibilities for analysis.
