Fitness Guardian - Stop scrolling. Start earning your screen time.

by
Fitness Guardian turns physical activity into a currency. It blocks distracting apps and unlocks them only when you burn calories. Unlike traditional app blockers or productivity tools, it doesn’t rely on willpower. It connects real movement with screen time, helping you reduce procrastination, stay active, and build discipline naturally.

Hey everyone 👋 I built Fitness Guardian because I realized how much time I was losing to mindless scrolling. I tried app blockers, timers, productivity tools… but they all relied on willpower. And honestly, that doesn’t work long term. So I thought - what if your apps simply stopped working until you actually moved? That’s how Fitness Guardian was born. It blocks distracting apps and lets you unlock them only by burning calories. Your movement becomes your screen time. I wanted something simple: - No complicated setup - No external tracking apps needed - No data leaving your phone Just move → earn time → use apps. I’ve been using it myself and it completely changed how I approach both my phone and daily activity. Would love your feedback, ideas, or anything you’d improve 🙏
