FuelRelay

FuelRelay is an offline nutrition and hydration planner for multisport athletes who want to plan their nutrition strategies for training sessions, race days, and long endurance events. The app helps you organize your carbs, fluids, sodium, intake times, and personal endurance notes in one easy-to-understand plan.

Create detailed plans for swimming, cycling, running, rowing, skiing, strength training, or multisport stages of your choice. Each plan can include event type, day, duration, intensity, weather, support points, individual foods, carbs per hour, fluids per hour, and sodium per hour.

The home screen displays the closest meal plan, total carbs, fluids, sodium, planned intakes, and alerts for overloaded sections. Compact cards make it easy to open, copy, delete, or view saved meal plans.

The nutrition chart turns each plan into a vertical timeline for water, gels, bars, salt, caffeine, and regular food. Users can manually add intakes, move them along the timeline, mark them as completed, skipped, or swapped, and instantly see progress toward their chosen goal.

The product library stores individual nutrition products with name, type, serving size, carbs, fluid, sodium, caffeine, tolerance level, and notes. Users can create, edit, archive, and quickly add products to race or training plans.

The analysis screen compares planned and actual intake by hour, stage, and entire session. Simple tables and graphs show carbs per hour, fluid per hour, sodium per hour, long no-intake intervals, overloaded sections, and remaining requirements.

After a workout or race, an endurance diary helps you record what worked, where you felt uncomfortable, energy levels, thirst, cramps, nausea, product substitutions, and personal notes. These notes help you create more realistic future plans based on local history.

A small additional camera feature allows users to attach a single local photo of the product label to a product card. The app is fully functional without a camera, accounts, servers, cloud sync, or network requests.

With a dark sports interface, compact plan cards, clear timelines, blue and purple accents, and local storage only, FuelRelay helps endurance athletes improve their nutrition habits and prepare effective nutrition strategies offline.
