Following tenCube exit, Darius Cheung launches BillPin, an app to track who owes what

After the acquisition of tenCube by McAfee in 2010, observers have been eagerly anticipating what Darius Cheung, co-founder of the mobile security company, might work on as his next venture.

They didn’t have to wait too long for his second act: His new app, BillPin, was released on iTunes over the weekend.

The new mobile app essentially lets you easily keep track of shared expenses and bills with friends. It is designed to provide an overview of how much money you’re owed at one glance.

You can also create events, such as ‘dinner with friends’, to remind yourself on what occasion you or your buddies picked up the tab. The app also lets you notify your dinner-mates over email about the shared expenses.

What’s missing is the ability to actually pay your bills in-app, although I’m sure the team is thinking about it and might even have that feature planned in their product roadmap.

Social money management apps are not exactly new though: BillMonk is a similar app in the United States that was launched in 2006 and acquired in 2007. Splitwise and Billsup also have similar functionality.

It’s unclear if BillPin will take off in Asia, but Darius’ re-entry into the startup game, along with Eddie Chau who sold Brandtology and started V-Key, certainly points to a greater maturation of Singapore’s startup ecosystem as a whole.
