Mirrorfootball.co.uk and 3am.co.uk, a showbiz gossip site, will launch paid applications in the new year. However, planned applications offering digital versions of the Daily Mirror and Scotland's Daily Record will be free.
“There are over one million iPhones in use in the UK at the moment and now that the handset is available across a number of network operators the number of subscribers will increase so this is the perfect time for Trinity Mirror’s portfolio of apps to hit the market," said Rick Gleave, Head of Interactive and Mobile at Trinity Mirror.
“Brands have demonstrated that it is possible to successfully position themselves in both the mobile internet market and applications market and benefit from both."
More Trinity Mirror applications are planned for 2010. The company has a portfolio of five national newspapers, over 120 regional newspapers and 400 plus digital products.
Earlier this week, The Guardian launched a paid mobile version of the newspapers website.
The Guardian application costs £2.39 and becomes one of the first news applications that users must pay for. The The newspaper hasn't ruled out the possibility of charging for extra functionality at some point in the future.
The Guardian iPhone application offers topic-based search, the ability to download and read content without internet connection using the 'offline reading' option and the opportunity to personalise your home screen.
Available from the Apple iTunes App Store, The Guardian costs £2.39 and requires the iPhone 3.0 Software Update.
