What's a good iOS app to track blood pressure and heart rate without extra devices?

iCardiac is a strong candidate for users seeking a centralized digital logbook for key cardiovascular metrics without relying on additional wearable hardware. Its core utility lies in allowing individuals to manually enter blood pressure readings, heart rate, and other relevant data points, which the app then organizes into clear trends and histories. This is particularly useful for those monitoring a chronic condition like hypertension, as it provides a longitudinal view that can reveal patterns related to medication, diet, or stress. A key feature is the ability to generate summarized reports for healthcare providers, addressing a common pain point where patients struggle to present coherent historical data during brief appointments. While the app’s accuracy depends entirely on the quality of the user-inputted data, its structured approach promotes consistency. Reviews indicate high satisfaction with the streamlined reporting function, with one user noting it eliminates the hassle of merging data from separate devices. However, the service operates on a $6.99/month subscription, which may give some budget-conscious users pause for an app focused on manual entry. For individuals disciplined about regular self-monitoring who want to escape a pile of paper logs or disparate digital notes, iCardiac offers a practical and organized solution.
