App with the ability to connect to your exercise machine and act like an old video game with different levels

This would be an app that connects to your machine either through Bluetooth or with a sensor on your machine. the app would then track speed distance and calories burned. The main app screen would be a simple old video game format displaying your character on a map with different levels. Each level would be a specific distance or a certain number of calories. The twist would be that each level would have different game like obstacles or different environments that you need to overcome or exercise through. Throughout the levels you would collect points and power ups and even encounter enemies that might set you back. It’s the same idea as those apps that simulate walking through fantasy worlds except this would be a more video game type app
