Horribly named yuilop has secured 4.5 million euros (roughly $5.75 million) in Series A funding for its social communication apps for Android and iOS.

Hamburg, Germany-based Shortcut led the round alongside Russian VC Bright Capital (part of RU.COM) and private telecom investor Bruno Ducharme.

Nauta Capital, the Spanish investment firm that pumped 1 million euros in seed capital into the company earlier, also participated.

Yuilop builds mobile apps that enable users to message each other for free. The company will soon add support for free voice calls to boost its competitiveness with regards to other apps like Viber, Voxtrot, Tango and fring.
