If you have an iPhone, then there is another video calling app to add to the list of FaceTime, Skype, Fring, Tango, Ustream, ooVoo and the list goes on. The new entrant is TU Me, which in the UK will have many thinking it was written by the Chuckle Brothers from childrens TV, who had a catch phrase 'to me, to you'.
TU Me was developed by Telefonica, and will be promoted to O2 and other Telefonica mobile network users, users on other networks appear to be able to register using their mobile number.
The app is limited to the iPhone at present, and users should watch their levels of data usage if they make video calls over the mobile network. The app can only make calls and send texts to other TU Me users, but for those in areas with limited or no mobile reception, but reasonable WiFi from their broadband router, it may provide another way of reaching people.
