Memory gaps
Clients have limited memory of elevated stress moments, if they noticed at all. Critical patterns go undetected because they're never reported.
Phase 1 · Now available
Biometric intelligence for better clinical outcomes.
InterSession IQ pairs wearable-grade biometrics with the context that happens between sessions, so therapists arrive prepared and clients feel seen, never surveilled.

The Limitation of Traditional Therapy.
Today, psychotherapy sessions only include information clients can recall while in session, usually leaving out a vast amount of information that could be vital to high quality assessment.
The Data Gapwhat therapists miss between sessions
Time in session1 hr
Time between sessions167 hrs
Therapists traditionally have visibility into less than 0.6% of a client’s week. InterSession IQ changes this by providing continuous insights.
Subjective reporting
Self-reported stress levels often don't match physiological reality. Clients may report feeling 'fine' while their biometrics show chronic stress.
Missed opportunities
Without insight into clients' entire week, therapists can only intervene based on what the client remembers at the time of their therapy session.
Care that listens, between sessions.
Three surfaces, one connected loop. Biometric signal, AI-assisted synthesis, and a calm interface that respects how clinicians actually work.
Biometric intelligence
Heart rate, HRV, sleep stages, stress, activity, and mood, all ingested from Apple Health and visualised against personal baselines, not population averages.
Between-session context
Highlights what changed since your last visit, surfaces homework completion, and delivers in-app homework reminders, so the first ten minutes aren't a recap.
Privacy by default
Health data is encrypted server-side, role-scoped on every Convex query, and never leaks into logs, analytics, or URL parameters. We treat opaque IDs as the norm.
From daily life to your weekly session.
Three simple steps connect the week you actually lived to the time you spend with your therapist, so heart and mind stay on the same page.
Bring your data in
Export from Apple Health, Oura, or a CSV and upload it in a tap. Direct device sync and an iOS companion app are on the way.
See the story in your signal
We analyse heart rate, HRV, sleep, activity, stress, and mood against your own baseline, surfacing trends, stress episodes, and what changed since last time.
Arrive already understood
Your therapist reviews an AI-assisted weekly report, threshold alerts, and homework before your session, so the first ten minutes aren't a recap.
For therapists
Walk into every session already 80% briefed.
See the week your client just had, not in raw data, but in the shape of a story. Alerts surface the moments that matter, AI reports condense weeks into minutes, and homework completion is one glance away.
- AI-generated session summaries you can edit before notes
- Configurable alert thresholds per client (HRV, sleep, mood)
- Schedule conflicts caught before you double-book
For clients
Share the patterns that matter, nothing more.
Sync from Apple Health, answer a short intake, and let your therapist see the patterns that matter. You stay in control of what gets shared and when. No social feeds, no streaks, no gamification.
- Sync biometrics straight from Apple Health on iOS
- Calm, ad-free interface designed by clinicians, not growth hackers
- See your own trends. Your data is yours, fully.
Built for the work between sessions.
InterSession IQ works for anyone with a smartwatch who wants to see progress in their therapy or personal mental health journey.
People managing anxiety and stress
Track multiple biomarkers throughout the week to understand your patterns, then review them with your therapist instead of reconstructing the week from memory.
Therapy clients seeking better outcomes
Maximize every session by arriving with objective data about your week. Bridge the gap between sessions and give your therapist insights they've never had access to before.
People managing panic attacks
Heart-rate spikes consistent with tension or panic are flagged in your synced data with the full onset, peak, and recovery timeline, so you and your therapist can review what happened and look for triggers.
Couples in therapy
See your therapy work through the week with homework tracking, and bring objective context into conversations about how each of you responds to stress.
Built for sensitive data
Privacy You Can Depend On.
We treat biometric and personal data like the regulated material it is. The product is designed so the easy path is also the safe path for therapists, for clients, and for the team that audits us.
Encrypted end-to-end
Integration tokens and sensitive payloads are encrypted server-side. Transport is HSTS-enforced HTTPS only.
Opaque IDs everywhere
Stripe metadata, webhooks, emails, and logs use opaque identifiers. No names, diagnoses, or notes in transit.
Least-privilege by default
Therapist / client boundaries are enforced on every Convex query, not just in the UI. Auth is checked server-side, every time.
FAQ
Questions, answered plainly.
What InterSession IQ does today, how your data is handled, and what we’re still building.
How does InterSession IQ work?
You bring biometric data from your wearable - exported from Apple Health, Oura, or a CSV - and upload it to InterSession IQ. We analyse heart rate, HRV, sleep, activity, stress, and mood against your personal baseline and turn it into clear, between-session insights you and your therapist can act on. Direct device syncing is coming soon.
Do I need to manually log how I'm feeling?
No detailed journaling required. Your insights are generated from your wearable data, not symptom diaries. A short intake sets context up front, and you can revisit or update it any time.
Is my data private and secure?
Yes. InterSession IQ is built with a HIPAA-conscious architecture. Health data is encrypted in transit and at rest, access is scoped to you and the therapist you choose to connect with, and we keep names and sensitive details out of logs, URLs, and third-party metadata. We never sell your data.
How do I share data with my therapist?
Your therapist sends you an invitation link. Once you connect, they can review your reports, trends, and alerts before your sessions, and you stay in control of the connection.
What devices and data sources are supported?
Today you can upload Apple Health exports, Oura data, and CSV files (including Health Auto Export). Direct device syncing and an iOS companion app are in active development.
How accurate are the AI insights?
Our analysis highlights patterns across multiple signals to support your conversations in session. It's a clinical aid, not a diagnostic tool - the insights are meant to be interpreted and discussed together with your therapist.
This is Phase 1.
The foundation ships first: synced biometrics, weekly reports, and session prep. Here’s a look at what we’re building next.
Client journaling
A lightweight space for clients to add context to their data, shared with their therapist on their own terms.
Real-time awareness
Alerts when biometrics shift in the moment, not just in retrospect, so support can arrive when it matters.
AI-assisted interpretation
Narrative summaries of biometric patterns with clinician oversight, clear AI labeling, and HIPAA-compliant processing.
