To launch this rising artist, we developed an incredible new piece of tech that will match one of his many songs to your BPM, ensuring you get the exact Russ song to fit your heartbeat.

By writing an algorithm from scratch that detects micro-fluctuations in the phone’s accelerometer, we were able to turn the phone into a heart rate tracker. We did this without creating a whole new an app, and just using a mobile browser that uses the phone’s accelerometer to detect your heartbeat. All you have to do is hold it against your chest, and we’ll match your beat to one of Russ’.

The algorithm we wrote from scratch detects micro-fluctuations in the phone’s accelerometer, and from this we were able to turn the phone into an accurate heart rate tracker. We do this by passing the accelerometer through a smoothing function, then recording the time between peak values to accurately find your BPM. And once the heart rate is identified, the site will pair one of Russ’ songs with an identical BPM, and play it via his Soundcloud page.

Once the site launched, Russ shared it with his loyal fanbase and there was no stopping it. 92% of users completed the experience all the way through, and now he’s the fastest growing artist in 2017, with over 40 million hits on his SoundCloud page that he launched just two years ago.
