So I built gamification into the core of the app: Daily streaks that cost you something when you break them XP + levelling system 5-tier daily missions with chest rewards Weekly leagues (Bronze → Diamond) Friends leaderboard The hardest part I built: an AI food label scanner that reads any nutrition panel — UK, US, AU, EU, and even handwritten farmers' market labels. No barcode needed. Point the camera, wait 2 seconds, done. I don't actually like AI food scanners because they are never accurate. The app is live on Google Play now: NutriBalance I'll be posting about nutrition science, Android dev, and indie app growth here.…
