Building simple, precise and quantified aerodynamic and metabolic real-time in field measurement instruments for endurance athletes. We develop api solutions for teams, coaches and companies in the field of aerodynamic and metabolic diagnostics. Our Aerotest is a high-end aerodynamic outdoor test with all GPS-trackers and power meters to measure and optimize your CdA- and Crr-Values. Use our apps for full automated testing and guiding. Our Powertest tells you way more than your threshold – it tells you how it is composed: with VO2max and VLamax. These parameters define who your are! Additionally you get your threshold, FATmax, energy consumption, ... and it tells you which training works best for you and how much you should do… but that is only the beginning. We have optimal solutions to test this running and cycling. Our Powertest is the leading tool in this field. Our Simulation tools offer you a great range to take a vew on the influence of different factors on a defined course or race. The default view of our simulation shows you what change Power, CdA or Weight can have on the final time of a race. You can choose from one of the already available courses in our database or to upload one you have as a GPX file. In the biometric view of our tool you additionally have the chance to simulate Power, CdA and Weight changes in regards to your stored energy level and your capacity to intake carbohydrates. Our online platform allows you to visualize, analyze and share all the data from our services. A one hand solution.
