Speedometer use cases

Picking the right page

Each use-case page covers setup, accuracy limits and safety for one activity. Start with the activity you do most and set the app up before you move.

Safety across activities

Whatever you do, set up before moving. The GPS estimate is a helper; the road, water or trail comes first.

Choosing a mount

Every activity needs a different mount: dashboard or vent for cars, handlebar for bikes, armband for runs.
