About this app

Fuel your ambition.

We’ve all been there: You are preparing for a race or a long ride, reaching into your stash, only to find your favorite gel has expired or you ran out of bars. Or even worse: You hit the wall ("bonk") during training because you didn't plan your nutrition properly.

SUPLiR connects the dots. It is the first app that combines a smart inventory for your sports nutrition with a scientific fueling strategy for your endurance performance.

Key Features:

πŸ“¦ 1. Smart Inventory Keep full control over your stash of gels, bars, powders, and chews.

Expiration Tracking: SUPLiR alerts you before your products expire. Stop wasting expensive nutrition.

Stock Management: Know exactly what you have on hand and when it's time to restock.

All in one place: Organize your nutrition regardless of the brand.

⚑ 2. Personalized Fueling Strategy Create the perfect nutrition plan for your Running and Cycling sessions. The game changer: SUPLiR uses the actual products from your inventory to build the plan.

Precise Calculation: Based on your age, gender, and fitness metrics (e.g., FTP for cycling), the app calculates your exact hourly carbohydrate and hydration needs.

Actionable Advice: Instead of just telling you to "eat 60g of carbs", SUPLiR tells you exactly which bar or gel from your pocket to eat.

Avoid the Bonk: Plan your energy intake before you start and keep your performance steady.

Why SUPLiR? Nutrition is the fourth discipline in endurance sports. SUPLiR takes the guesswork out of your fueling. Whether you are training for a triathlon, a gran fondo, or a marathon – start prepared.
