Gamification to Increase Mobility in the Hospital

Inclusion Criteria: * Admitted to a medicine or cardiology floor in the hospital * Age 50 years or older * Have an AMPAC (mobility scale) score of greater than or equal to 21 or a Braden mobility sub-scale score of 4. Exclusion Criteria: * Inability to provide informed consent * Does not have daily access to a smartphone compatible with the wearable device and not willing to use a device that the study team can provide * Inpatient AMPAC score of less than 21 or a Braden mobility sub-scale score less than 4 indicating that independent physical activity may not be appropriate for the patient * Are already enrolled in another physical activity study * Any conditions that would prohibit participation in an inpatient physical activity program (at the discretion of attending physician or nurse caring for the patient in the hospital). To minimize the risk of contamination across study arms, we will only approach one patient per hospital room in shared rooms
