About this app

You bonked at km 80. Not because you trained badly — because you guessed.
SUPLiR keeps an inventory of the gels, bars, drink mixes and chews you actually own, then turns a planned session into a timed fuelling plan built from that stock. Grams of carbohydrate per hour, item by item, with hydration, sodium and caffeine ceilings respected.
The Fuel Planner does the work. Pick the sport, set the duration, choose the intensity zone, and it holds the carbohydrate target against your ceiling, then fills every slot from what is on the shelf. Move the duration and the whole plan re-times itself.

IN VERSION 3.0
· A rebuilt Pantry — your whole inventory at a glance, with what expires first
· A Live screen for fuelling during the session, not before it
· Before, during and after surfaced on the dashboard when each phase is active
· A complete visual redesign

WHAT IT DOES
· Timed fuelling plans from your own products, not a generic table
· Carb loading across the three days before an event, 8–10 g/kg
· A phased 48-hour recovery protocol
· Caffeine timed 45–60 minutes before peak effort, inside your daily limit
· Import from Strava, Komoot, Garmin Connect, .ZWO, .GPX and .FIT
· Built on your numbers: weight, FTP, VO2max, carb ceiling

FOR
Cyclists and runners training six to twelve hours a week, racing two to four times a year, who want the fuelling to be as considered as the training.



SUPLiR is a planning tool, not medical advice. Consult a professional for individual nutritional guidance.
