Why is it free?
I built WattsUP because I needed a clean, distraction-free tool for my own cycling training. I wanted my winter indoor trainer workouts and summer road miles in one unified training-load model, without paying $20 a month to a gaming company or having my fitness telemetry locked away.
I pay the hosting and database bills myself every month. My goal is to make this app free until I can't pay the hosting cost any longer. For the time being, it is completely free for everyone.
If server costs ever grow beyond what I can personally sustain, I will give the community clear, honest advance notice. And your data will never be held hostage—you can always export your full ride archive.
