CarbPlanner: Race Nutrition
Endurance fuel & hydration
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Know exactly what to eat and drink — and when — so you never bonk. Set your carb target, add your gels and bottles, get a timed plan for every ride.
Bonking isn't bad luck — it's a fueling plan you didn't make. CarbPlanner builds that plan for you.
Tell it how many grams of carbs per hour you want, add the gels, bars, chews and bottles you'll actually carry, and CarbPlanner lays them out on a minute-by-minute timeline so your energy stays steady from the gun to the finish.
WHY IT'S DIFFERENT
• Timing that respects your body. A 40 g gel lasts longer than a 20 g one, and a bar takes far longer to absorb than a gel. CarbPlanner spaces every feed around how your gut actually works — not just evenly on a clock.
• Route-aware fueling. Import a GPX file and CarbPlanner reads the terrain: it front-loads energy before climbs, keeps feeds on the flats, and stops asking you to eat mid-climb or on a technical descent.
• Hydration, not just carbs. Plan your bottles with real sodium numbers, adjusted for heat and intensity so you drink enough without overdoing it.
BUILT FOR RACE DAY
• A live timeline that tells you what to take and when, as the session runs
• Notifications so you never miss a feed
• Product search to pull in real carb and sodium data, or add your own
• Session history — reuse any past race as a template for the next one
• A shareable plan card for your ride buddies
ON YOUR WRIST AND LOCK SCREEN
• Apple Watch: your next feed on your wrist, with a haptic tap when it's time
• Live Activity and Dynamic Island: the countdown stays on your Lock Screen
• Barcode scan: point at a gel or drink mix and pull in its real numbers
Whether it's a Saturday gravel epic, a marathon, or a full-distance triathlon, CarbPlanner turns "I think I've got enough gels" into a plan you can trust.
Plan your fuel. Nail your hydration. Finish strong.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Two fixes from riding with it.
• Add a gel in the last quarter of a session and it now lands ahead of you with a reminder, instead of quietly slipping behind the current time. With ten minutes left, adding something can only mean "take it now" — so that is what it does.
• If a backup is found when you reinstall, CarbPlanner asks whether to restore it before the welcome screens, not after. You no longer set everything up only to replace it a minute later.
