What does the app do?

The app enables you to keep track of your daily fluid intake, weight and blood pressure. It allows you to set limits for these measurements and alerts you if your blood pressure or weight reaches a level that means you need to tell your healthcare provider. The app has provision for you to add doctors' appointments to a diary, create medication lists and store questions for your healthcare provider. It also has information about heart disease, kidney disease, low sodium levels and dietary tips.
