Some magnetometers can be calibrated for nearby iron masses, while others cannot. Those that can are generally more expensive (by several times). The $50-60 models do not. If I pick one up, I'll report my real world experience. If the magnetometer is parked up on the bars with the phone and it works then it will be a great feature for those interested in the cost. If it doesn't work, I doubt anyone including myself would have interest paying $300 for a compass that works when you aren't moving.
