It gets the step count from the device itself so it does not need to be running at all times to track it. I think it just keeps track of what the number was the last time you opened it and what the number is the next time you open it and it awards you the difference.

If the accelerometer is running, it’s drawing power, but perhaps that can be done efficiently on some devices.

The sensors (accelerometer, gyroscope, etc.) are anyways already running on the majority of devices, so WalkScape doesn’t really add to that. The only times it does draw power is when you boot it up and use it. But even that draws very little power - I’ve developed my own game engine on top of Flutter, which is an SDK to build apps and is very battery friendly out of the box!
