I used TrainerRoad for my indoor bike workouts during Winter. Its subscription costs $20 per month, which seemed unreasonable for the one thing I was using: the workouts. So I decided to create an free and open-source alternative. I've been using it for almost a month now and it feels great to have built something useful for once :)
