FuelReminder

Glycogen & Hydration — real-time fueling for your ride Bonking and dehydration end more rides than tired legs do. This full-screen data field continuously estimates how much carbohydrate you've burned and how much fluid you've sweated — and reminds you to refuel and drink before it's too late, even when you're looking at a different data screen. WHAT IT SHOWS — a four-quadrant dashboard: CARBS USED (g), FLUID (L), CARB g/h (current burn rate), REFUEL IN g (grams until the next reminder). ALERTS THAT ACTUALLY REACH YOU — Refuel tone every 45 g of carbs burned, Hydrate tone every 0.5 L of sweat (both adjustable). They run off the activity computation, so they fire no matter which page you're viewing. 10-minute cool-down per alert. HOW IT WORKS — power-meter-based when available (watts + FTP), auto-falls back to a heart-rate estimate otherwise. Carb share rises with intensity; sweat scales with intensity and temperature. Weight/HR from your profile, FTP read from your device. Works with ANT+ or Bluetooth sensors. HONEST ABOUT THE NUMBERS — estimates from population-average physiology, not lab values. Shows carbs burned in grams (not "% glycogen left") because storage varies too much per rider.
