Those looking to make or gift a unique jewelry piece will want to download the 'Crafted By My Heart' app.
The app has users place a finger over a smartphone's camera and flash in order to detect a person's unique heartbeat. By covering this specific part of a phone, users are able to see sublte changes in color as blood flows into the fingertip. At the same time, the app shows a pattern on-screen to reflect the unique pulse.
Once the heartbeat-recording process has finished, users are able to order a 3D-printed ring in a variety of finishes and styles. In order to ensure that all designs are one-of-a-kind, Crafted By My Heart takes the extra step to assign a new algorithm to each ring design.
