Third-party blood pressure monitors are available for the iPhone, such as the QardioArm, the iHealth Labs monitor, and the Withings monitor. These devices sync with the iPhone through their respective phone apps to provide feedback to the user.
All blood pressure monitors provide real-time health status to the user, can chart results over time, and can share data with the user's physician, but each device also has unique features. The QardioArm allows the user to track his blood pressure at specific locations and can also create a support network with the user's friends and family to keep them apprised of changes to his health. IHealth Labs' monitor features a physical charging dock for the phone. The Withings monitor features automated, secure cloud backup.
