Second Brain

Read full description

The first ADHD app that comes ready to use - no setup, no configuration, no building from scratch. Every productivity app expects you to design the system yourself. By the time you're done setting up, you've already lost momentum. Second Brain flips that. Open the app and you'll find a library of 20+ real-life tasks - paying bills, refilling prescriptions, scheduling appointments, doing laundry, filing taxes - each broken into small, clear steps you can follow one at a time. DAILY ROUTINES Install a Morning Routine, Evening Wind-Down, or Sunday Reset and get guided through your day one card at a time. Customize them or build your own. CHECK-INS Gentle prompts throughout the day. Feeling off track? Tap into a recovery flow and reset without judgment. HANDS-FREE MODE Tasks are read aloud as you go - perfect for mornings when your phone is across the room. SMART DEFAULTS Recurring tasks regenerate automatically. Tasks surface when they're due - not before. Your most recent task stays at the top. Less clutter, less thinking. No account. No cloud. No subscription. Your data stays on your device. Built for the ADHD brain that wants a second brain - without having to build one.

Your head, but quieter. ADHD Notes is a calmer task and follow-up app built for brains that run many threads at once. Stop holding everything in your head. Capture it, keep it in context, and let the app surface what needs you next. WHY IT IS DIFFERENT Most task apps make you file everything into projects and nested folders. For an ADHD brain, too much structure becomes friction. ADHD Notes keeps work visible on one flat board with a simple promise: get it out of your head, and let the tool carry it. CAPTURE FROM ANYWHERE Type it, paste an email, speak it, use Siri, or tap the Home Screen widget. The assistant can turn messy thoughts into clean tasks with the right dates, people, and context. ONE THING AT A TIME A focus mode with a quiet timer, gentle check-ins, and a live countdown on your Lock Screen. No noise, no nagging. IT REMEMBERS FOR YOU Recurring nudges resurface what slips. Follow-ups can move out of sight until tomorrow. A plain-language Daily Brief tells you where things stand. Reminders bring tasks back exactly when you asked. FULL CONTEXT ON EVERY TASK People, customers, meetings, notes, subtasks, links, and history live on the task card. Nothing scattered, nothing lost. RIGHT FROM YOUR HOME SCREEN Home Screen, Lock Screen, StandBy, and Apple Watch support. Ask Siri to capture a thought. Find tasks with Spotlight. MADE FOR YOUR BRAIN Flat by design, with no nesting to get lost in. Calm colors, quiet motion, lighter visual noise, and forgiving undo patterns. Deleted items wait in Trash for 30 days, so mistakes are easy to recover. Free to start. You could be carrying less in five minutes.
