Mobile health apps are proliferating, but they fail to deliver on a key patient and caregiver requirement - the ability to collaborate using key phone features while leveraging existing web services. Typically, mobile health apps are for single use, proprietary, and deliver closed-world solutions. By making use of web services, both open and proprietary, mobile health apps can be created to support the caregiver network in the community. The full value of telehealth will only be achieved when the spectrum of trusted health care services (preventive, promotion, curative, and rehabilitative) is delivered to the collaborating network of caregivers.
