Your steps unlock your apps. It's that simple. Free forever for early adopters! Zeno is a unique screen time app that connects your physical movement to your phone usage. Walk 1,000 steps, earn 10 minutes of app time. No complicated systems. No harsh blocking. Just a simple trade that helps you move more and scroll less. --- THE PROBLEM 5-6 hours. That's how much time you spend on your phone each day. Most of it happens on autopilot - opening Instagram in bed, scrolling TikTok between tasks, falling into YouTube rabbit holes. You've tried Screen Time limits. You've tried willpower. They don't work because they fight against your brain instead of working with it. --- A DIFFERENT APPROACH Zeno doesn't punish you for wanting to use your phone. Instead, it asks one simple question: Have you moved today? • Walk 1,000 steps → Earn 10 minutes of app time • Walk 3,000 steps → Earn 30 minutes • Walk 10,000 steps → Earn 100 minutes Your body becomes the unlock key. Every step counts toward the apps you actually want to use. --- HOW IT WORKS 1. Choose Your Apps Pick 2-3 apps that drain your time and focus. Instagram, TikTok, YouTube, X - whatever your "brain rot" apps are. 2. Set Your Window Block access during your most vulnerable hours. Morning? Evening? You decide when you need protection most. 3. Walk to Unlock Zeno reads your steps from Apple Health. As you move, you earn credits. Spend credits to unlock your apps. 4. Stay Accountable See exactly how much time you've earned versus spent. Gentle nudges help you walk more when credits run low. --- WHY ZENO IS DIFFERENT Unlike other blockers that rely on willpower alone, Zeno creates a positive feedback loop: - Want to scroll? Go for a walk first. - The walk improves your mood and focus. - By the time you've earned your time, you often don't need it. - And if you do use it, you've already done something good for yourself. This isn't about restriction. It's about earning. --- PERFECT FOR • Morning doomscrollers who reach for their phone before getting out of bed • Students and professionals who lose hours to social media • Anyone managing ADHD who needs gentle friction, not harsh rules • People who want to move more but struggle to find motivation • Anyone tired of Screen Time limits they ignore after 5 seconds --- FEATURES • Steps-to-Minutes Conversion — Simple 1,000 steps = 10 minutes formula • App Selection — Choose which apps require credits to unlock • Morning Block Window — Protect your most vulnerable hours • Credit Dashboard — See exactly what you've earned and spent • Apple Health Integration — Automatic step counting, no extra devices needed • Privacy First — All data stays on your device. No accounts required. --- THE ZENO PHILOSOPHY Named after the ancient philosopher who taught that small, consistent actions lead to wisdom, Zeno believes the same about your attention. You don't need to quit social media. You don't need extreme digital detoxes. You just need a simple trade: movement for screen time. Walk first. Then scroll. --- PRIVACY BY DESIGN We don't want your data. We want you to walk more and scroll less. No servers are storing your information.

####################### Tired of screen time apps that are too easy to unblock? — Same. We believe: The only thing that can keep you off your phone is having to PAY FOR IT! Lock4Good helps you take back control of your phone usage. And if you do want those extra minutes? Buy them. — WE DONATE ALL PROFITS TO A CHARITY OF YOUR CHOICE! SAVE TIME. DO GOOD. ### HOW IT WORKS Pick the apps you want to limit and set your own daily limit for each. Lock4Good tracks your usage in the background. When an app reaches its limit, it is blocked for the rest of the day. Ideally, you stick to your own limits, but if you really want more time, there are four ways to unlock a blocked app: • A free emergency minute, once per app per day, no payment • An optional paid unlock (+5 or +20 minutes) • The automatic reset at midnight • Deleting Lock4Good, which lifts every restriction instantly ### DO GOOD What you buy in Lock4Good is additional screen time. We donate all profits from these unlocks to a charitable organisation of your choice: GiveWell, GiveDirectly, Against Malaria Foundation, Médecins Sans Frontières, Action Against Hunger, Save the Children, WWF, or Amnesty International. You can change it at any time. ### YOU STAY IN CONTROL Lower or delete any limit freely at any time before it is reached. There are no accounts, no logins. Just the functionality you need. ### PRIVACY FIRST Your app selections, limits and usage never leave your device. Crash reporting and analytics are off by default and fully optional.
