This app uses the iPhone's camera lens and flash to measure your heart rate from your fingertip. The results are amazingly accurate! You are probably thinking that this is a joke right? Can this FREE app really measure my heart rate accurately? Well.... YES IT CAN! But Hey... Don't take our word for it, Download this FREE app right now and find out for yourself! TIP: For best results keep your finger still and make sure your finger tip is placed gently over the camera lens and covers it completely. If you press too hard it can reduce blood flow in your finger giving you a less accurate result.

If you have any questions or concerns about your heart health always consult your doctor.
