Build and run custom protocols combining questionnaires, guided activities, and smartphone camera measurements, including heart rate, breathing rate, and heart rate variability (HRV), without wearables or a custom app.
LEESBURG, Va., Nov. 10, 2026: Last week, Presage Technologies, maker of camera-based contactless vital signs software, launched eSSESSMENT®, a self-serve, no-code platform that lets researchers, coaches, and wellness teams run longitudinal studies and daily check-ins combining questionnaires with smartphone-camera vital signs, without wearables or a custom app.
eSSESSMENT serves research labs tracking adult participants between lab visits, performance coaches running athlete readiness check-ins, and wellness programs tracking progress between sessions. A team can build protocols consisting of survey questions, guided breathing exercises, and camera readings of heart rate, breathing rate, and heart rate variability (HRV). Participants complete the protocol on their own phones in Presage’s free Coherence app, so the team has no app to build and no wearables to ship.
Readings in Coherence and eSSESSMENT come from SmartSpectra, Presage’s contactless sensing engine, which uses remote photoplethysmography (rPPG) to measure heart rate and HRV from subtle changes in skin color on video, and breathing rate from upper-body movement, using only a standard camera. Presage’s published model cards report mean absolute errors of 0.36 beats per minute for pulse rate against ECG and 0.37 breaths per minute for breathing rate against capnography.
“What people tell you and what you can measure belong in the same assessment,” said Mark Oliver, founder and CEO of Presage Technologies. “With eSSESSMENT, researchers, coaches, and wellness teams can bring their own questions together with camera-based vital signs in a single check-in. Now they can build and run those programs themselves, on the phones people already have, and keep learning between sessions.”
Who eSSESSMENT Is For
- Health Research Teams: Researchers and healthcare organizations launching remote health studies and clinical trials, collecting patient-reported outcomes, or testing new participant check-in protocols without building a custom app.
- Academic and Clinical Researchers: Teams running ecological momentary assessments (EMA), experience sampling, and daily diary studies with adult cohorts who want physiological data between lab visits without shipping wearables.
- Psychophysiology, HRV, and Breathwork Labs: Labs that compare heart rate, breathing rate, and HRV before and after paced breathing.
- Strength Coaches, Athletic Trainers, and Gym Trainers: Staff who work with adult athletes and run daily readiness check-ins and wellness questionnaires without chest straps or smart rings.
- Wellness Programs and Coaching Teams: Organizations and club coaches working with adults who check in with participants between sessions to track engagement, stress, and recovery.
How It Works: No-Code Activity Builder, ChatGPT, and Claude Integration
A team can describe its protocol in plain language to ChatGPT or Claude. The Coherence connector for Claude or for ChatGPT then builds that protocol as a program in eSSESSMENT. For example, a lab can type: “Build a daily check-in with a 2-minute paced breathing exercise and a survey about the participant’s current energy levels. Capture heart rate, breathing rate, and HRV during the breathing exercise and survey.”
The team reviews the result in the no-code Activity Builder, or builds the protocol there step by step. During a check-in, a participant uses the free Coherence by Presage app on their phone to complete the breathing exercise and survey while the phone’s camera takes a reading of heart rate, breathing rate, and HRV. Each camera reading carries an automated reliability score. The team then reviews completed sessions in eSSESSMENT, including each participant’s physiology traces across the entire capture, and adds notes or downloads the data for further analysis.
Common Questions
How fast can a team deploy a contactless vital signs check-in on participants’ phones?
Because participants use the existing Coherence by Presage app rather than custom software, a team can build a protocol and invite participants instantly. Participants install Coherence by Presage from the App Store or Google Play.
How does eSSESSMENT support longitudinal health research?
eSSESSMENT helps research teams follow participants over time through repeated check-ins on their own phones. Teams can collect surveys, questionnaires, and patient-reported outcomes on the study’s schedule, with optional guided activities and camera-based heart rate, breathing rate, and HRV. These check-ins build a longitudinal record that helps researchers explore day-to-day patterns and baseline physiological changes affecting program participants, complementing data collected during lab or clinic visits.
Can a study collect heart rate and HRV without wearables?
Yes, if the protocol includes a camera reading. Participants answer questions while the phone’s camera reads heart rate, breathing rate, and HRV. The survey answers and physiological readings are collected during the same session, and each reading carries a reliability score.
How does eSSESSMENT protect participant privacy and research data?
eSSESSMENT encrypts data sent over public connections and encrypts primary databases and saved recordings at rest. Access is controlled at the organization level, and archived audit records are kept in tamper-resistant storage. Organizations choose whether supported live activities save video, audio, or both, and measurements, questionnaire responses, and results are stored separately from video.
How do coaches run an athlete readiness check-in without wearables?
A coach builds a short routine once in eSSESSMENT. The routine can include a 30-second resting scan, paced breathing, a repeat scan, and one readiness question. Adult athletes complete the routine in Presage’s free Coherence app before practice.
Pricing and Availability
Presage Technologies’ eSSESSMENT is available today for research, coaching, and wellness programs at presagetech.com/essessment, with no sales call required. Teams can create an organization and start building protocols on their own. The Coherence app for participants is free to download on iOS and Android.
Clinical Evidence and Regulatory Status
In a peer-reviewed, Presage-sponsored Baylor College of Medicine study of 111 healthy adults, about 96% of captured heart rate readings were within 3 beats per minute of ECG. On June 18, 2026, Presage’s SmartSpectra Vital Signs Monitor 1.0 received FDA 510(k) clearance (K254169) for trained healthcare professionals to spot-check pulse and respiratory rate in adults; eSSESSMENT and Coherence use the same SmartSpectra sensing technology for general wellness and research and are not FDA-cleared.
About Presage Technologies
Presage Technologies is a contactless vital signs company that turns ordinary cameras into health sensors. Its SmartSpectra engine captures heart rate, breathing rate, heart rate variability (HRV), electrodermal activity, and facial expressions, and is in clinical validation for contactless blood pressure measurement. It uses phone, laptop, and device cameras without wearables. SmartSpectra powers eSSESSMENT, the self-serve platform for expert teams, and Coherence, Presage’s free app for individuals and program participants. Developers and device makers can integrate the technology through the SmartSpectra SDK.
