Hi Hunters! 🚀 I'm the maker of Aerix. As a runner myself, I found myself constantly opening a calculator or searching for formulas before hopping on a treadmill or planning a race. Existing apps were great for tracking, but cumbersome for quick calculations. So, I built Aerix using TypeScript to be the fastest "pocket knife" for runners. It works directly in your browser (no heavy app stores needed!). I'm particularly interested in your feedback on: 1. Is the Karvonen Heart Rate calculator intuitive to use? 2. What other "math problems" do you face while running that I could solve with a new tool? I'm planning to expand the "Running Wiki" section to connect theory with these practical tools. Thanks for checking it out, and happy running! 🏃💨
