User activity including both athletic activity (e.g., running, walking, etc.) and non-athletic activity (shopping, reading articles, etc.) may be monitored and tracked by an athletic monitoring and tracking device and service. The user activity may be used to award a user with an amount of virtual currency to encourage the user to continue various activities. In one example, users may use the virtual currency to purchase or otherwise acquire various products, services, discounts and the like. A user may track an amount currency earned and/or needed relative to an amount required to acquire a desired product or service. Additionally or alternatively, a visual appearance of a user device (e.g., a watch or athletic activity band) may change based on the user's activity level, an amount of virtual currency earned and the like.

An Internet of Thing (IoT) device includes a sensor coupled to a processor; and a transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A skeleton support has a concave shape configured to fit around a nose and mouth of a user. The support includes a skeletal structure that defines a plurality of connecting regions which form a first common connection interface. A cover includes a mounting mechanism with a plurality of fastening units which form a second common connection interface corresponding to the first common connection interface. Each fastening unit is configured to removably engage a corresponding connecting region of the skeleton support to hold the cover together with the skeleton support and form a mask. Different skeleton supports or covers with a different size, shape, color, pattern, flexibility, or material that also include the corresponding common connection interface can be swapped out to adjust the mask.
