"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/

Reminders that don't go away. Every reminder gets its own card on your Lock Screen, and it stays there until you deal with it. No badge to miss, no list you have to remember to open. Swipe the card away and it's done. If you have ever closed a reminders app and forgotten the reminder existed, Linger is built for exactly that. WRITE IT THE WAY YOU'D SAY IT Type "water the plants every Tuesday at 8am" and Linger reads the schedule out of the sentence. It shows you what it understood, so nothing gets silently misread. Every repeat you'd actually want is there — daily, weekdays, every Tuesday and Thursday, the 1st of the month — without a form to fill in. FINISHING IS ONE GESTURE Swipe the card off your Lock Screen and the reminder is complete. A repeat rolls forward to its next date on its own. You never have to open the app at all. SEE WHAT IT ADDS UP TO Every reminder keeps a grid of each day you ticked it off — months of it, readable at a glance. Streaks count themselves. It's the difference between thinking you've kept something up and knowing you have. PUT SOMETHING DOWN WITHOUT LOSING IT Archive takes a reminder off your Lock Screen and out of the list, and keeps its whole history. Bring it back whenever you like and the grid comes back with it. Something archived in March and restored in August returns on its next real date, not five months overdue. YOUR REMINDERS NEVER LEAVE YOUR PHONE No account. No sign-up. No ads, no analytics, no tracking of any kind. What you write is a file on your device and nowhere else — there is no copy of it on any server, ours included. ALSO • A Home Screen widget, so it's there before you unlock • Fourteen colours, so a glance tells you which is which • Dark mode, lit properly rather than dimmed • A backstop notification, so a reminder can never quietly vanish FREE, AND WHAT PLUS ADDS Linger is free to use, with one reminder on your Lock Screen at a time. Linger Plus lifts that limit — keep as many as you like, each on its own card — and is a monthly or yearly subscription, or a one-off lifetime purchase. The yearly plan starts with seven days free: the whole app, nothing held back. We'll remind you the day before the trial ends, so it can't turn into a charge you didn't expect. SUBSCRIPTION DETAILS Linger Plus is available as a monthly subscription and a yearly subscription, both auto-renewing, and as a one-time lifetime purchase that never renews. The price in your local currency is shown on the purchase screen before anything is charged. A subscription renews at the end of each period unless auto-renew is turned off at least 24 hours before that period ends. You can turn it off at any time in your App Store account settings.
