One strategy. Ready before the start and simple to follow under pressure.
Fuelstate is a running nutrition planner and live fueling companion for iPhone and Apple Watch. It turns your profile, planned distance and pace, weather, terrain, gut tolerance, and the products already in your kit into carbohydrate, fluid, and sodium targets; caffeine guidance where relevant; and a practical packing and timing plan. During the run, that prepared plan stays close through live countdowns, audio, haptics, the Lock Screen, and Apple Watch where supported. See how the full workflow connects.
The race-day blind spot
Your training is precise. Why is your fueling still a guess?
Pace has a plan. Training has a plan. Fueling is often still a note, a screenshot, or a rough interval. At mile 20, memory is not a system.
One thought before the run. One action during it.
Decide clearly. Pack once. Follow through.

The questions that matter.
Fuelstate is a running nutrition planner and live fueling companion for iPhone and Apple Watch. It turns the runner, run, conditions, course context, and preferred products into a strategy to prepare, pack, and follow.
No. Fuelstate works on iPhone. Apple Watch adds wrist-based prompts and controls if you want them.
Yes. Fuelstate can build around products in its catalog and custom products you add, so the strategy reflects what you already trust and carry.
No. Fuelstate complements coaching and professional nutrition care by helping make a run fueling strategy practical and executable. It is not medical advice.
Yes. You can build a personalized strategy for any run. Supported race presets add course context where it is available.
Fuelstate builds the strategy from the runner, planned distance and pace, conditions, gut tolerance, relevant preferences, and the products selected for the run. It turns those inputs into practical targets, quantities, and timing.
Fuelstate translates nutrition targets into product-specific packing guidance. You can see what to take before the start, what to carry during the run, and the quantities needed for the planned strategy.
Fuelstate carries the planned fuel timing into the run through iPhone and Apple Watch surfaces, including live countdowns, prompts, audio, haptics, and glanceable run information where available.
No. Fuelstate can build fueling strategies for training runs, half marathons, marathons, trail runs, and ultras. The inputs and selected products shape the strategy for the specific run.
Yes. Fuelstate can record completed or skipped fuel events and support a post-run review of execution, fueling quality, gut feedback, and product patterns over time.
