Less to hold in your head. ADHD Notes is a calm place to capture thoughts, see what needs you, and follow through. Keep tasks, notes, meetings, and plans together without turning organization into another full-time job. CATCH THE THOUGHT Save a quick thought in Remember. Keep your original words, then decide what belongs in a task, a note, or your plans. Use text, voice input, Siri, the share extension, or a widget when it is convenient. SEE TODAY CLEARLY Find due and overdue tasks in Today. Use Board for the bigger picture, priorities, and waiting work. Due dates, reminders, and recurring nudges help bring open loops back into view. KEEP NOTES USEFUL Write notes, make checklists, pin what matters, and keep a journal. Find your ideas again instead of rebuilding them from memory. MAKE MEETINGS LEAD SOMEWHERE Keep the agenda, notes, people, and follow-ups in context. Carry the next step forward from one conversation to the next. GIVE YOUR PLANS A PLACE Use calendar and agenda views to see time alongside your work. Keep projects moving and separate work, personal, and school life with workspaces. FOCUS YOUR WAY Choose one task and an optional timer. Focus is there when it helps, without requiring another routine to maintain. ON THE DEVICES YOU USE Use ADHD Notes on iPhone, iPad, and Apple Watch. Home Screen widgets, Siri and Shortcuts, the share extension, and Spotlight give you more ways to capture and find things. Your account also connects with the web and Android apps. Features vary by platform. YOUR WORDS, YOUR CHOICE Optional AI workflows explain what will be sent and ask for permission. Review suggestions before saving them. Core organization does not require accepting an AI suggestion. Some features require an account, permissions, a paid plan, or service availability. ADHD Notes is an organizational tool, not medical advice or treatment. Start with one thought. Carry less.

This month's challenge is open to everyone • Milestone moments at 7, 30, 100 and 365 days, with an image to share • Insights: this month against last, the habits that lift each other, your best time of day and when each chain hits its next milestone • Log Next Habit in Control Center, on the Lock Screen and on the Action button • A Best Chain widget that looks great in StandBy, and a Lock Screen line under the clock • Ask Siri "How's my chain?"
