Supplemental: Therapy Journal
Capture insights & prepare
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Make more of therapy between sessions. Capture insights as they happen, prepare what you want to discuss, and turn breakthroughs into small daily practices.
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.
