Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Additionally, techniques for utilizing altimeters in biometric monitoring devices are provided. Such techniques may, in some implementations, involve recalibrating a biometric monitoring device altimeter based on location data; using altimeter data as an aid to gesture recognition; and/or using altimeter data to manage an airplane mode of a biometric monitoring device.
