The Chicago-based online deals website announced its number of mobile app users increased by more than 3 times between last December and December of 2010.

It now has over 9 million people who use Groupon from their smartphones.

The company says 25 percent of Groupon vouchers in December were purchased using a mobile phone.

Groupon is also expanding a partnership with Nokia to offer location-based services to Nokia phones.
