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.

Read full description

Nudge is the ADHD companion that checks in on you like a good mate — not a clinical tool that talks at you. Built for adults managing their own ADHD and parents helping their kids stay on track, Nudge brings your entire day into one calm, clear view. MEDICATION MANAGEMENT Track your ADHD medications with precision timing. See when your next dose is due, how long until it kicks in, and get gentle push notifications so you never miss a window. Log each dose with a single tap. FOCUS TIMER Lock into deep work sessions with customisable focus timers and ambient sounds. Set goals, track your sessions, and build a rhythm that works with your brain, not against it. DAILY CALENDAR SYNC Connect your Outlook, Gmail, and Apple calendars so you can see your full day in one place. No more switching between apps to figure out what's next. MOOD & ENERGY TRACKING Quick daily check-ins to log how you're feeling. Track your energy levels throughout the day and spot patterns over time. See how your medication, sleep, and habits affect your mood. DAILY CHECK-IN Start your day with a simple overview. Nudge shows you what's ahead, reminds you what matters, and keeps you grounded — one block at a time. WHY NUDGE? Most ADHD apps try to do too much or feel like they were built for someone without ADHD. Nudge is different. It was designed to be the one app you actually come back to throughout the day — simple, clear, and always on your side. No judgement. No overwhelm. Just a gentle nudge to keep you going. This app is not a substitute for professional medical advice, diagnosis, or treatment. Always consult your doctor regarding your medication and health decisions.
