SUPLiR was developed for endurance athletes – primarily for cyclists and runners. The app is aimed at anyone who takes their training and competitions seriously and understands that proper fueling is often the limiting factor for peak performance.

Nutrition is the fourth discipline. SUPLiR solves two problems simultaneously:

1. Chaos in the Cupboard: You always know exactly what you have in stock and what is expiring.
2. Uncertainty during the Race: Instead of guessing, the app calculates exactly what you need to eat and when to meet your carbohydrate needs based on your inventory.

SUPLiR combines three core areas in one app:

1. Smart Inventory: Digitize your stock of gels, bars, and powders, including expiration date monitoring.
2. Fuel Calculator: Calculate scientifically based nutritional strategies for your sessions.
3. Analytics: Keep track of your consumption and inventory development.

SUPLiR is a project by ambitious amateur athletes. It is completely free to use.

SUPLiR can be found for Android smartphones in the Google Play Store and in the Apple App Store for iPhones and iPads.

SUPLiR accesses your planned routes on Strava and helps you find the perfect fuel plan for your next challenges. If no routes are displayed for you to choose from, it may be because you haven't saved any routes. It's best to quickly check your Strava account.

The Fuel Calculator in SUPLiR is based on current, evidence-based guidelines in sports nutrition. Calculations for carbohydrate and fluid requirements follow recommendations from leading sports science institutions (such as ACSM, ISSN) and are based on the physiological oxidation rate of nutrients during exercise. You can find more details on our Science Page.

SUPLiR already has a large database of popular sports nutrition products. As soon as you start entering the brand and product, suggestions from the database will be displayed. If your product isn't listed, you can either type the information directly or use the built-in image recognition. To do this, tap the camera icon. Ideally, take a photo of the back of your product so that the brand, name, flavor, nutritional information, and expiration date are visible. The image analysis will attempt to recognize as much information as possible and fill it in on the input form.

No. You can use the app without a SUPLiR account, but you will forego a backup of your data. Without an account, your data cannot be restored if you delete the app or change your phone.

The account enables Cloud Sync. This means:
1. Your data is safe, even if you lose your phone.
2. You can log in on multiple devices (e.g., tablet and smartphone) later and see the same inventory everywhere.
3. Your individual settings (FTP, weight) remain intact.

Linking is optional but very useful. SUPLiR uses the interface to synchronize your planned routes. This allows you to create a fuel plan for your next session directly without further input and keep an overview.
