The Hipbone app is offered by Open mHealth (New York, New York, USA; https://hipboneapp.com/), a non-profit start-up seeking to increase the clinical relevance and usage of self-generated health information.1 Since Apple's release of the iOS 8 operating system in September 2014, iPhone users have been able to collect and curate a variety of their own health data using the native Health application. A signification limitation, however, is that self-generated data, while appreciable in the Health app dashboard, are only stored on the device.
