My BP is always under 130/85. In fact all readings today are between 113/81 (83) and 128/83 (81). Yet when I check the statistics/analytics it says I have stage one hypertension. My numbers are not in that category. This is a useless misleading app. Uninstall and check out other ones. If you don't understand hypertension numbers this could make a healthy person think they're having health issues.
