The most beautiful thing an app can do is get out of your way. Sumi sits quietly on cream paper, holds your attention for an hour, and asks for nothing back. Set a length. Put your phone face down. Pick it up before the time is done and the session breaks — not as a punishment, but as a commitment kept. No ads. No notifications. No streaks-as-slot-machines. No weekly subscription trap. Just deep work, and the quiet record of the hours you've given it. — THE RITUAL — Set an intention and a length. Put the phone down. Sumi keeps watch: lift it, or leave the app, and the session ends. When the time is held, the line completes, your lifetime hours grow, and the session is logged. Silent while you work. Quietly rewarding when you finish. — A CALM LEDGER, NOT A GAME — The number that only goes up: your lifetime hours focused. A streak, if you want one. A week that fills, a line that climbs. No characters to feed, no points, no dark patterns. Progress you can feel, with nothing engineered to hook you. — MADE FOR DEEP-WORK PEOPLE — For writers, developers, designers, students of a craft — anyone who already romanticizes focus and resents apps built to fracture it. Graphite and cream. Monospace. Paper grain. A single calligraphic mark. — PAY ONCE — Your focus shouldn't be a recurring charge. Sumi is free to use, with an optional one-time Lifetime unlock (or a subscription, if you prefer) for custom lengths, full history and trends, themes, and session intentions. Put the phone down. Pick the work up. ——— Privacy Policy: https://dayonefoundry.com/sumi/privacy Terms of Use (EULA): https://dayonefoundry.com/sumi/terms

"Find Resonance in Your Solitary Exploration." See the threads, and the questions not yet asked. Right after a session ends is often when your mind is fullest. Countertransference lingers, a boundary question remains unresolved, and an unasked question keeps circling—yet your next human supervision session is still days away. ECHO is not a clinical supervisor and does not provide professional supervision. It is a case-reflection and independent client-management workspace for counselors and psychotherapists—supporting everyday reflection, client organization, and preparation for your next session or qualified human supervision. [ CORE CAPABILITIES ] - Independent Client Profiles & Session History Create a dedicated profile for each client to organize consultation type, frequency, core concerns, risk observations, and session progress over time. Client profiles, scheduling, and session records work independently without requiring a reflection report. - Practice Calendar & Clinical Scales Manage upcoming appointments and daily session flow in one view. Prepare and send standard clinical scales (PHQ-9, GAD-7, PCL-5) before sessions begin. - On-Device Transcription & Selective Submission Capture what stayed with you in text or use on-device audio transcription to review pauses, repetitions, and key moments locally—then decide which de-identified excerpts to submit for reflection. - Framework-Informed Case Reflection Using psychology frameworks, ECHO organizes therapeutic technique, working alliance, ethical boundaries, and transference/countertransference clues into testable hypotheses and structured reflection questions—keeping private reflection separate from SOAP notes, DAP notes, and formal clinical records. - Practice Statistics & PDF Handover Review consultation hours, active clients, and session trends locally on your device. Export clean A4 PDF reflection reports for your physical case folder or to share with your human supervisor (for remote or in-person supervision). - Privacy by Design & Private iCloud Continuity Activate across iPhone, iPad, and Mac with one License Key—no traditional account registration required. Session text is encrypted in the app's local database (AES-256), with continuity across your Apple devices through your own private iCloud container. Off-device analysis begins only when you actively submit selected text. ECHO performs a two-pass identifiable-information check before analysis and before report delivery; if safe processing cannot be confirmed, analysis stops, no report is returned, and the credit is refunded. [ PROFESSIONAL BOUNDARIES & DISAMBIGUATION ] ECHO is designed strictly for licensed counselors, psychotherapists, and qualified mental health practitioners (and supervised trainees within applicable ethical rules). It is not intended for client or patient use. ECHO does not provide professional supervision, establish a supervisory relationship, diagnose conditions, issue treatment instructions, handle crisis intervention, serve as an EHR or formal medical-record system, or replace qualified human supervision and professional judgment. ECHO on echo.gifts is not affiliated with Project ECHO or Extension for Community Healthcare Outcomes. Privacy Policy: https://echo.gifts/privacy/ Terms of Service: https://echo.gifts/terms/
