Hi bunda! There are quite a few blood pressure tracking apps available, some of us use ones like Blood Pressure Companion or Qardio, they're pretty straightforward for logging your readings regularly. But honestly, if you're dealing with high blood pressure, best to get checked by your doctor first to make sure you know what numbers you're aiming for, then the app just helps you keep track day-to-day. My mum friend swears by keeping a simple notebook too, some doctors actually prefer that over apps!
