Focus fuel

Every minute you focus builds something real. Focus Fuel turns your productivity into a construction project. Start a focus timer, and a crew of animated workers breaks ground on a new building — from Cozy Cottages to Luxury Villas. Stay focused and watch your house rise. Quit early, and it crumbles. Your sessions shape a persistent living world that thrives when you're consistent and decays when you're not. It's productivity you can see. ━━━━━━━━━━━━━━━━━━━━━━━━━ 🏗️ FOCUS TIMER • Quick-start presets: Pomodoro (25 min), Deep Work (50 min), Quick (15 min) • Custom timer from 5 to 120 minutes • Full Pomodoro structure with configurable work, short break, and long break durations • Pause, resume, or complete early (at 80%+ progress) • Motivational progress updates as you build 🏠 BUILD REAL STRUCTURES • 5 house tiers unlocked by session length — from cottages to villas • Watch your animated crew carry materials, hammer walls, lay bricks, and raise the roof in real time • Meet the crew: Dave "The Boss", Mike "Hammerhand", Tony "Brickwall", Sam "Muscles" & Jake "Sky Walker" • Earn coins for every minute of focus 🌍 YOUR LIVING WORLD • A persistent world that grows with your focus and decays from inactivity • Health, growth, and decay systems track your habits visually • Streaks reward consistency; missed days trigger gradual decay • Watch your world thrive, stabilize, or struggle — it reflects your real habits 🎵 AMBIENT SOUNDS (NO ADS, NO DOWNLOADS) • 6 mathematically synthesized soundscapes — no audio files needed • White Noise, Brown Noise, Gentle Rain, Ocean Waves, Lo-fi Drone, and Focus Beats (binaural alpha waves) • Auto-plays during sessions with full volume control 🔒 FOCUS LOCK • One-tap Do Not Disturb mode blocks notifications and distracting apps • Automatically activates during focus sessions • Grace period system: a 10-second warning if you leave the app mid-session 📊 DEEP INSIGHTS & ANALYTICS • Hourly and monthly focus distribution charts • Session success rate tracking • Weekly consistency score (0–100%) • Peak focus times, best streaks, and detailed session history • Performance-based tips tailored to your habits 💌 MESSAGES FROM YOUR FUTURE SELF • Weekly auto-generated letters based on your real performance data • Three tone categories: thriving, improving, or struggling • Personalized with your actual stats — sessions, minutes, streaks, and consistency • Archive of past messages to track your growth over time 🎯 DAILY GOALS & STREAKS • Set a daily focus goal (15–480 minutes) • Visual progress ring on your home screen • Current streak and best streak tracking • Consistency scoring that weighs active days, completion rate, and streak length 🔐 100% PRIVATE • All data stored locally on your device • No cloud sync, no tracking, no third-party analytics • Purchases processed securely through Google Play ⭐ PREMIUM (ONE-TIME PURCHASE) • Unlimited focus time (free tier: 30 minutes) • All themes unlocked (Ocean, Forest & more) • Advanced analytics with detailed charts • Regenerate Future Self messages anytime • Exclusive building designs and workers • Premium motivational quotes • No ads, ever Start building your world — one focused session at a time.
