Accelerometer based speedometer

[zijincheng]

Hi, I'm looking for a speedometer app.

However, I don't have data so I can't connect to GPS and can't use many of the apps, can anyone recommend a speedometer app that works entirely offline?

Impossible, simply because the accelerometer can't provide data regarding your movement speed. Accelerometer works in a different way to spedometers, they don't measure point to point change in velocity. And you don't need data to connect to GPS.
