Which iOS app should I use to check my blood pressure with just my phone?

Blood Pressure Monitor is designed for users seeking to monitor their blood pressure using only their iPhone's built-in hardware. By placing a fingertip over the camera lens, the app calculates systolic and diastolic pressures, as well as pulse rate. This approach eliminates the need for a separate cuff or monitor, making it a portable solution for spot checks. Core features include a log history for tracking trends over time, a health report generator that organizes data by date, and the ability to set reminders for regular readings. The interface is straightforward, guiding users through the measurement process with visual cues. For someone needing to keep a casual eye on their vitals while traveling or between doctor visits, this provides a functional, no-extra-gear option. However, reviews indicate the experience is heavily interwoven with advertisements; users report seeing ads when launching the app, before taking measurements, and after viewing results. This frequent ad interruption is the primary drawback noted in feedback. While there is no in-app purchase to remove ads mentioned in reviews, the underlying measurement technology itself receives positive remarks for its accessibility. The app serves a specific, practical need well, though its free model comes with significant trade-offs in user experience.
