Introducing Heart Tempo - a new, beautiful, and simple way to instantly get your heart rate, the tempo from that song, or the rhythm of anything else. Simply feel your heart beat from your chest and tap out the beat on your display and get a measurement from that sample, which you can then instantly share or save to the Apple Health app! You can do the same for the tempo from that song you like, or the rhythm to anything else in the world around you - just open your device and tap out the beat! It's as simple as that! You can refer back to your past measurements in your private history tab, so you can use them in the future. Of course, you can always remove a measurement from the history tab whenever you please. Heart Tempo has a beautiful and intuitive design, presenting you with the app in all its elegance with no difficulty to use. The app does not track you, discretely sell your data, or record your measurements secretly. The app is ad-free. Only you and who you decide to send it to will be able to see your measurements. No other third-party - including me, the developer - will ever see your measurements.
