Singaporean firm Billpin, which enables users to split bills, has acquired larger US rival BillMonk for an undisclosed fee, according to Tech in Asia.

BillPin, which only launched in February, has acquired its US competitor from Obopay, a mobile payments provider which bought BillMonk in 2007.

Bill splitting services enables users to settle payments such as rent, utility bills and meals online or through a mobile app.

BillPin co-founder Darius Cheung did not reveal the subscriber count for the two services but he did say that the larger BillMonk had  “probably more than 50 times our user base”.
