Should have ZERO
Ridiculous. I have been using this app to track my BP. I have a major issue going on and need to show my doctor this information. I’ve diligently saved each BP standing and sitting three times a day. Today all my history is vanished. Saving this data is literally the only function of the app. I am so disappointed. Total Fail of an app and now I don’t have what I need for my cardiologist tomorrow
