About

Cognitive Diary

Read full description

Cognitive Diary is a private, privacy-first space for self-reflection, emotional awareness, and everyday mental well-being. The app combines CBT-inspired journaling tools, guided breathing exercises, and validated self-assessment questionnaires to help you better understand your thoughts, emotions, and reactions โ€” at your own pace and without pressure. You can choose from structured journal formats inspired by cognitive behavioral techniques, including thought tracking, anxiety and trigger monitoring, activity planning, emotion regulation, exposure tracking, and mood reflection. These tools help organize inner experiences, notice patterns, and explore alternative perspectives in a calm and non-judgmental way. Cognitive Diary also includes simple breathing exercises designed to support moments of stress or emotional overload. Visual breathing guidance helps slow down and reconnect with the body. You can use the app without creating an account. Signing in is optional and unlocks PRO features, including secure end-to-end encrypted cloud synchronization across devices. Your privacy is a core principle of the app. All entries and test results are encrypted. Encryption keys never leave your device, and you remain in full control of your personal data. Important disclaimer: Cognitive Diary is not a medical device and does not provide medical advice, diagnosis, or treatment. It is not a substitute for professional healthcare or mental health services. If you are experiencing severe or persistent mental health symptoms, please seek help from a qualified professional. Cognitive Diary is designed as a supportive self-reflection tool and a private companion for building awareness and self-regulation skills in everyday life.

About

ThroughLine App

Features
Read full description

Therapy happens once a week. Everything else happens in between. ThroughLine is an AI-powered support tool for people in therapy, designed to help you make the most of the time between your sessions, not just the hour you're in the room. Start with a 14-day free trial. After your trial, full access requires an active ThroughLine subscription. Reflect. Between sessions, things come up. ThroughLine gives you a quiet space to process what's on your mind, guided by questions that help you go deeper than a blank page would. Your reflections build over time, creating a thread you can actually follow. Plan. Before each session, ThroughLine draws on your reflections to help you shape what you want to bring to your therapist. You arrive with clarity instead of starting from scratch. Continue. After each session, capture what happened while it's fresh. ThroughLine helps you hold onto the insights and intentions that can otherwise fade before your next appointment. Your reflections are yours alone. Everything you share is encrypted, and your data is never used to train AI models. ThroughLine is a tool, not a therapist, but it's built for people who take their therapy seriously.
