Kora: Energy & Focus Tracker - Your phone locks distracting apps until your body says go

Kora turns your health data into one Energy Score (0-100) built from sleep, HRV, heart rate, and daily check-ins. Then it does what no other app does — locks your most distracting apps behind real health goals. Walk 5,000 steps to unlock Instagram. Sleep 7+ hours to access TikTok. AI coaching learns your patterns and tells you when to push and when to rest. Works with or without Apple Watch. Free to start.

Hey PH! 👋 I'm Relja, a 20-year-old solo iOS developer from Serbia. I built Kora because I kept lying to myself about how I felt. I'd wake up after 5 hours of sleep, tell myself I was fine, and immediately open TikTok. An hour later I'd start working already drained — and have no idea why my day fell apart. My Apple Watch was collecting all this health data, but it just sat there. Numbers on a screen I never acted on. So I built Kora to fix both problems at once. It takes your real health data — sleep, HRV, heart rate, activity — and turns it into one Energy Score (0-100) that tells you how you actually feel, not how you think you feel. But the part I'm most proud of is Shields. Instead of just showing you data, Kora actually locks your most distracting apps behind real health goals. Want Instagram? Walk 5,000 steps first. TikTok? Get 7 hours of sleep. Your body sets the rules, not your willpower. I built this entire thing solo — SwiftUI, HealthKit, Firebase, AI coaching — and I use it every day myself. Would love your feedback: What app would you lock behind a health goal? What health metric matters most to you? I'll be here all day answering everything 🙏
