Some days you're a productivity machine. Most days you're running on empty. Every other to-do app was built for the machine days, and quietly makes you feel broken on all the rest. Ikoi is the to-do list and daily planner for brains that don't run in a straight line. You pick the energy you've got, and Ikoi picks the task to match. WHY IKOI WORKS WHEN OTHER PLANNERS DON'T Most apps open to a wall of everything you haven't done. That's not a plan, it's a guilt machine. Ikoi shows you one thing at a time, sized to the energy you actually have right now. No infinite list, no red badges shouting at you. RUN ON YOUR REAL ENERGY, NOT YOUR IDEAL ONE Set your mode, Zombie, Okay, or Hyperfocus, and your list quietly reshapes around it. Low-spoon day? The heavy stuff steps back until you're ready for it. START BEFORE YOU FEEL READY Every task keeps a 2-minute first step, because starting is the wall, not the work. Do the tiny thing, then focus in a quiet Pomodoro session once you're moving. NOTHING PILES UP, NOTHING SHAMES YOU Cap your day in spoons and let skipped tasks fade instead of stacking. Build habits and gentle routines that bend on hard days instead of breaking, with reminders that nudge rather than nag. A HOME FOR EVERY LOUD THOUGHT Brain-dump it all and sort it later, or never. Turn a thought into a task, a reminder, or nothing at all. No judgment. MADE TO BE LIVED IN Six hand-drawn pixel-art themes, cozy and warm. A planner that feels like a game you want to open, not a spreadsheet you have to. MADE FOR People with ADHD, autistic folks, anyone in burnout or recovery, students drowning in deadlines, and every brain that's tired of apps built for someone else's. No guilt. No overwhelm. Just the next small thing. Terms of Service - https://ikoi.app/terms Terms of Use (EULA) - https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy - https://ikoi.app/privacy

About

Odysseus knew he couldn't resist the Sirens, so he had himself tied to the mast. Mast does the same for your phone. Screen Time limits are easy to dismiss. Mast is different: you create commitments, scheduled blocks where your distracting apps lock, and you decide up front what it takes to get them back. Your apps don't just come back when time passes. They unlock when you act. HOW IT WORKS 1. Choose the apps that steal your time: TikTok, Instagram, games, anything. 2. Schedule your commitments: study sessions, work hours, mornings, evenings. 3. Pick your unlock policy, what it takes to earn your apps back: โ€ข Photo: snap a photo to prove you did it: gym clothes on, books open, bed made โ€ข Timer: run down a focus timer before anything unlocks โ€ข Mark done: apps stay locked until you check the task off โ€ข Just wait: or simply lock yourself out for a set time WHY IT WORKS Psychologists call it a Ulysses pact: a binding decision you make now, while you're clear-headed, that your weaker future self can't undo. Willpower fails in the moment, so Mast removes the moment. When the commitment starts, the ropes are already tied. There's no "remind me in 15 minutes" to tap through, and the only way out is the one you chose yourself. โ€ข Powerful blocking built on Apple's Screen Time technology โ€ข Flexible schedules for study, work, sleep or a full digital detox โ€ข See the hours you've won back If you have any ideas or questions, please email us at hello@usemast.app. Terms of Use: https://usemast.app/terms
