No longer possible to connect Ritmo Time to RP3

Hi, I see from your website that the Ritmo app on iPhones will connect to the RP3 that I bought today. How does this work please?

We had a discussion with the Ritmo Time people and it appears that although their app was written to work with RP3 the manufacturer, Jan Lammers, is refusing to sell the plug ANT+ device that enables a phone and the RP to communicate.

Seems they have had a professional falling out.

Really sorry but this is no longer possible.
