Which iOS app should I use for daily heart rate and blood pressure tracking without buying extra hardware?

Blood Pressure Log, Heart Rate is a focused utility for individuals seeking to monitor cardiovascular metrics using just their iPhone. The primary function involves placing a fingertip over the device's camera lens to capture a pulse reading, from which it calculates heart rate and estimates blood pressure. For anyone establishing a daily health routine, the app simplifies consistent tracking by storing each measurement with optional notes about activity, medication, or time of day. A key strength is its trend visualization; weekly and monthly charts help users identify patterns, such as elevated readings in the morning or after specific events. Reviews indicate the process is notably quick, with readings completed in under 30 seconds, making it practical for regular use. However, the accuracy of the blood pressure estimation is dependent on proper finger placement and stable lighting, and it should not be considered a substitute for medical-grade devices. The export feature for sharing data with healthcare providers is a thoughtful inclusion. While the app excels at core logging, some advanced metrics like Heart Rate Variability (HRV) analysis are presented in a simplified manner that may not satisfy data enthusiasts. Overall, it serves its stated purpose effectively for general wellness awareness.
