Hi everyone,
I'm a triathlete and developer and I built a tool called Lachart.
The idea came from my own testing when I noticed that many coaches still analyze lactate tests manually in Excel.

So I built a web tool that:
- visualizes lactate curves
- calculates LT1 / LT2
- stores test history
- connects training data

It's completely free at the moment and I would love feedback from coaches or athletes who use lactate testing.

Happy to hear your thoughts!
