What's the best iOS app for checking my heart rate using just my phone's camera?

Health Mate Pro is a straightforward application focused on measuring heart rate through a smartphone's camera and flash. The primary feature involves placing a fingertip over the camera lens to obtain a pulse reading, a method that provides a convenient, hardware-free way for casual monitoring. The app logs these readings, allowing users to track trends over time with simple date-stamped records. For someone wanting to quickly check their resting heart rate before or after a walk, or to monitor basic daily variations, this functionality covers the essential need. However, it's important to note that reviews indicate some users find the interface non-intuitive initially, with one 4-star review explicitly stating a need for clearer guidance on operation. This suggests the app excels in its core technical task but may require a brief period of familiarization. It is not intended for medical diagnosis but serves well for general wellness observation. The developer, Hainan shiqu network technology co. LTD, has maintained a high average rating, suggesting most users are satisfied once past the initial learning step.
