About

Cadence

Read full description

Your day, drawn around your rhythm — not against it. Cadence is the planner built for the way your brain actually works. Instead of rigid to-do lists that mock you when the day falls apart, Cadence quietly rebalances your plan so slipped tasks find the next right moment. No guilt, no rebuilding from scratch, no starting over tomorrow. Built for people with ADHD, suspected ADHD, autism, AuDHD, and anyone whose days refuse to run on a 9-to-5 timeline. WHY CADENCE • DAY FLEX ENGINE — When you miss a task, Cadence moves it to the next best slot in your day. No manual dragging. Your plan flexes with you, not against you. • ENERGY-BASED SCHEDULING — Tell Cadence once when your mornings, afternoons, and evenings run hot. High-energy tasks land in high-energy windows. Low-energy tasks stay out of the way. • GENTLE RHYTHM, NOT ALARMS — No jarring notifications. No red overdue counters. Just quiet suggestions that meet you where you are. • EVERYTHING LIVES ON YOUR PHONE — No sign-in, no cloud sync, no account to forget. Your answers, your rhythm map, your plan — all stored locally on your device. Nothing shared. HOW IT WORKS 1. A 90-second onboarding shapes the app around YOU — your energy pattern, the kind of mind you're working with, the things that usually drain you. 2. We generate your first week — tasks placed on the windows where your brain tends to show up. 3. Miss one? Day Flex moves it. Finish one? The rhythm shifts a little. Every day, the plan is a little more yours. CADENCE PRO Start with the basics for free. Upgrade when you want the full rhythm engine. PRO UNLOCKS: • Day Flex auto-rebalance — the engine that moves slipped tasks • Energy-based scheduling — automatic high/low-energy placement • Rhythm analytics + journal — see your weeks, track what shifts • Gentle notification nudges — calibrated to your pattern, not a clock • Focus mode — quiet, distraction-free task execution SUBSCRIPTION INFORMATION • Cadence Pro Annual: $59.99/year with a 7-day free trial • Cadence Pro Monthly: $9.99/month (no trial) Payment charged to your Apple ID at purchase confirmation. Subscription auto-renews unless cancelled at least 24 hours before the current period ends. Manage or cancel anytime in Settings > Apple ID > Subscriptions. Any unused portion of a free trial is forfeited when you purchase a subscription. Privacy Policy: https://cadence-legal.vercel.app/privacy.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Cadence isn't trying to fix you. It's trying to give you a day that fits. Quietly. Without the shame spiral. Without the blank Monday. Your rhythm is already in there. Cadence just listens.
