Forget the diamonds, there's a recession on. Instead, send your valentine a digital copy of your heartbeat.
Now, the web communications company has designed the Re:Beat app, which reads the user's pulse to detect their heartbeat, thus enabling them to send their 'heart' with a personal message to loved ones.
The reading is taken when the user places their finger on the phone's camera, and calculated by analysing the colour change of the finger when the flash goes off. The digital heartbeats can then be sent via Text, Facebook, and Twitter.
Anna-Ålenius Mathson, head of PR & communication at Rebtel, said: "Millions of people use Rebtel to stay in touch and for Valentine’s Day this year, we wanted to do something a bit different that was still related to our mission of providing free and low-cost voice and messaging services to our growing global user base.
"We think that sending your heartbeat to someone dear to you is a perfect way to express the depth of your love, especially if you’re not able to see them in person."
