Quick checks for the numbers you get at the doctor's office or on a home monitor, each with a plain-language explanation and the guideline it is based on, such as the American Heart Association for blood pressure and the ADA formula for A1C.

Questions
Is my health data saved or uploaded?
No. The calculations run on your device. The medicine reminder keeps its list in your browser's own storage, and nothing is sent to a server.
Can I use these instead of seeing a doctor?
No. They explain what a number means and where it comes from. Talk to a doctor about a reading that worries you. If a blood pressure reading is above 180/120 and you have chest pain, shortness of breath or trouble speaking, call 911.
