AltoThought is designed to guide you through reframing negative thoughts, enhancing your cognitive process. Originally created to support my own cognitive behavioral therapy journey, it is now available to assist you in reshaping your mindset. Here's how AltoThought works: Begin by jotting down your initial thought, whatever it may be, and note your current feelings. Next, visit the Alternative tab to explore a new perspective on that thought. This helps you add nuance and reshape any cognitive patterns that may be holding you back. Analyze your progress with insightful statistics that reveal how your feelings evolve through the practice of alternative thinking. Let AltoThought be your companion in developing a healthier and more balanced thought process.

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 — 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.
