Turn therapy sessions into private notes, clear recaps, and meaningful reminders you can revisit between appointments. Undertone is built for people already in therapy. It helps you hold onto what mattered, reflect between sessions, and come back to your next appointment with more continuity. Capture or upload a session, get a clean summary, save what you want to remember, and prepare for what to bring up next time. THERAPY SESSION NOTES • Record or upload session audio • Get a clear session summary with key themes, insights, and next steps • Keep past sessions organized in one place BETWEEN-SESSION REFLECTIONS • Revisit meaningful Moments from past sessions • Save thoughts, questions, and topics to bring into therapy • Keep homework and follow-through items easy to find • Review what came up without digging through scattered notes PRE-SESSION BRIEFS • See what you talked about last time • Review what you planned to work on • Bring forward important thoughts from the week • Walk into therapy with more continuity, not a blank slate A CALMER WAY TO STAY CONNECTED TO THERAPY Therapy can move quickly. Important insights, patterns, and next steps are easy to forget once the session ends. Undertone gives you a private space to return to the parts of therapy that matter most, so the work does not disappear between appointments. Undertone is not a therapist, crisis service, or diagnostic tool. It does not provide medical advice or replace professional care. It helps you organize, revisit, and reflect on the care you already receive. Undertone is built using HIPAA-aligned workflows.
