Energy Crash Tracker - Fuel

Stop guessing why you crash. Track energy, meals, caffeine and sleep to discover exactly what drains you - and beat it.

Why do you crash at 3pm? What actually drains your energy - the carb-heavy lunch, the bad sleep, or too little water? Fuel gives you the data to finally know.

Log your energy levels throughout the day. Add meals, caffeine, hydration, and sleep. After 14 days, patterns emerge - and you will know exactly what to change.

WHAT YOU TRACK

Energy Score (1-10) - Color-coded from green to amber to red. Your daily energy curve at a glance.

Meals - Log carb level and protein. Discover which foods tank your energy 1-2 hours later.

Caffeine - Real-time half-life calculator shows exactly how much caffeine is still active in your system right now.

Hydration - Track water intake toward your 64oz daily goal.

Sleep - Connect last night's sleep quality and duration to today's energy levels.

THE ENERGY TIMELINE Every day builds a precise timeline of your highs, crashes, and everything in between. See your 3pm slump on a chart. Understand the pattern before it happens again.

PREMIUM - FUEL PRO After 14 days of consistent logging, Fuel Pro unlocks your personal energy blueprint:
