Since many people loved the idea of my indoor cycling workout game but don't have the option to try it themselves, I decided to create a mini-documentary about my journey as a full-time indie game developer, building a SaaS app for smart trainers.
Thank you for your input, Steven. AppleTV is high on the roadmap for future product updates. Regarding your Wahoo sensors, they are all supported (except for the fan). I am not 100% sure about the SRAM power meter since there is some variation in the way different vendors support the Bluetooth sensor specification, so that is something you would need to try out. I would greatly appreciate your feedback if you ever have the chance to try the game.
Yes, the game supports most Bluetooth speed, heart rate, cadence, and power sensors, as well as most smart trainers and smart bikes. There is currently no support for fans or grade simulators.
It should be fairly straightforward to measure the cadence in the way you describe, but you would still need a way to measure input speed. Startona uses a physics simulation to calculate the player's speed based on the power input since this gives the most accurate results. In case power is not available, the game uses speed as a fallback. Although, it would be fun to add a way to connect an Arduino-based solution via USB so people can homebrew their own speed measuring systems (with hall sensors or similar). I am open to adding that option if enough people ask for it.
You could try to use a Bluetooth speed sensor like the "Wahoo RPM Speed Sensor" if your home trainer somehow allows you to fasten it to it's flywheel - if not, you would still have the option to put your bike on a cheap roller. That way the game would work, but you would only get a limited experience since only the high-end rollers support erg mode. At that point, you have come full circle and it may be cheaper to opt for an entry-level hub trainer like an Elite Suito.
Thanks a lot I appreciate it
Thanks, I see your point. The original design sketches were more similar to the minimalistic UI of the game. However, the main feedback there was that people felt the website did not portray the colorful contents of the game. As you said, the color also helps lift the screenshots, though I will probably add a little more animation to the page in the future since it feels a little bit static at the moment.

I spent the past three years developing an exercise game for indoor smart trainers called Startona. The game is built from scratch in TypeScript and only uses a couple of small libraries. The result is a PWA that showcases the capabilities of a modern web browser through technologies like Web-Bluetooth and WebGL.Developed to turn turbo-trainer workouts into intense gaming sessions, Startona...
