Your attention is a garden. Overgrow helps you take it back. Overgrow is a screen-time commitment device. You pick the apps that eat your day, set limits while you're feeling strong, and Overgrow holds you to them when you're feeling weak. Every time you resist the urge to open a distracting app, a living garden grows. Heavy scrolling and it gently wilts. It never dies, and there is no shame, just progress you can see. WHY OVERGROW IS DIFFERENT The limits you set are limits you actually keep. Tightening a limit applies right away. Loosening one only takes effect tomorrow, so you can't talk yourself out of your own commitment in a weak moment. No instant snooze. The only way out is deleting the app, and you'll feel that. HOW IT WORKS - Choose the apps and categories to block, powered by Apple Screen Time. - Set your rules: how many unlocks a day, the earliest hour you're allowed in, and how long each unlock lasts. - Open a blocked app and you'll meet a calm shield instead of the feed. Spend one of your limited daily unlocks, or stay focused and water your garden. - Watch your garden grow as your screen time falls. PRIVATE BY DESIGN No account. No login. No sign-up. Your Screen Time data never leaves your device. We never see the apps you block or how you use them. OVERGROW PLUS Overgrow is a paid app. A subscription to Overgrow Plus unlocks everything: - Block unlimited apps, categories, and websites - Always-on, hard-to-cheat blocking with your daily unlock budget and curfew - Your full focus history and a living garden that grows over time - Day-one access with a free trial on the yearly plan Start your 7-day free trial and reclaim your time.
