About

Second Brain

Features
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.
