Supplemental Capture insights. Stay engaged between sessions. Walk into therapy prepared. Supplemental is a therapy companion that helps you capture insights, prepare for sessions, and build small daily practices—so progress doesn’t stop when therapy ends. Most people leave therapy feeling clear and motivated. By the next day, life gets busy. Important thoughts are forgotten, breakthroughs fade, and the things you meant to discuss never make it into your next session. Supplemental helps you hold onto what matters. Capture Before You Forget Record thoughts, emotions, breakthroughs, patterns, and questions the moment they happen using voice or text. Everything is automatically organized, so your reflections are ready whenever you need them. Walk Into Therapy Prepared Build a Session Agenda naturally throughout the week instead of trying to remember everything at the last minute. Before your appointment, generate a clear Session Brief that organizes your themes, challenges, wins, and priorities into one easy-to-read summary. Spend less time remembering. Spend more time making progress. Turn Insight Into Action After therapy, transform your biggest takeaways into personalized daily micro-practices inspired by evidence-based approaches including CBT, DBT, and mindfulness. Small actions. Real momentum. Stay Connected Between Sessions Growth doesn’t happen one hour a week. Use reminders, guided reflections, and simple daily practices to stay connected to the work you’re doing long after your therapy session ends. Supplemental Pro Unlock advanced therapy tools including: • AI-generated Session Briefs • Personalized Micro Practices • Insight Mode • Smart reminders Designed to Support Therapy — Not Replace It Supplemental is designed to complement your work with a licensed mental health professional. It helps you remember what matters, prepare for meaningful conversations, and apply therapeutic insights between sessions. Supplemental does not provide medical advice, diagnosis, or treatment and should not be used as a substitute for professional mental health care. Subscriptions Subscription options are displayed in the app before purchase. Payment is charged to your Apple ID upon confirmation of purchase.

You think of it on Tuesday. By Thursday, in the room, it's gone. Between Sessions is a notebook built around the rhythm of therapy — the week, not the day. BEFORE THE SESSION Add to your agenda the moment something comes up. Walk in with a list instead of a blank stare. AFTER THE SESSION Capture the sentence your therapist said that you want to keep, the new framing, the thing you noticed. BETWEEN SESSIONS Track the work you take home — thought records, exposures, behavioural experiments — with reminders. CARRIED FORWARD Anything you didn't get to moves to the next session on its own. PRIVATE BY DESIGN No account. No cloud. No tracking. Everything stays on your device, behind Face ID. SHARE IF YOU WANT Export a single session or the last month as a PDF. Your call, off by default. Between Sessions is a notebook. It does not provide therapy, diagnosis or treatment.
