    What is Fuelstate?

    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.

    Do I need an Apple Watch?

    No. Fuelstate works on iPhone. Apple Watch adds wrist-based prompts and controls if you want them.

    Can I use products I already own?

    Yes. Fuelstate can build around products in its catalog and custom products you add, so the strategy reflects what you already trust and carry.

    Does Fuelstate replace a coach or sports dietitian?

    No. Fuelstate complements coaching and professional nutrition care by helping make a run fueling strategy practical and executable. It is not medical advice.

    Can I build a plan without a supported course preset?

    Yes. You can build a personalized strategy for any run. Supported race presets add course context where it is available.

    How does Fuelstate personalize a running nutrition plan?

    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.

    What does a Fuelstate plan tell me to bring?

    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.

    How does Fuelstate help during a run or race?

    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.

    Is Fuelstate only for marathons?

    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.

    Can Fuelstate help me review my fueling after the 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.

    Your next long run, planned.

    Build the plan tonight. Pack it in the morning. Hear it on the road.
