So its developer estimates, anyway.
Mobile developer Simon Maddox claims his 0870 iPhone app has saved UK users more than quarter of a million pounds in the two weeks since its release on the App Store.
The application is designed to save users money by finding alternative local numbers for the 0870 and 0845 numbers used by many UK companies for their customer services - charging as much as 35p a minute.
Maddox says in a blog post that the app was downloaded 91,722 times in the two weeks after its release on 25th September.
Based on an average saving of 35p per minute, and an average call length of five minutes, he reckons that those users have collectively saved £267,987.54 during that fortnight - this is based on the number of successful conversions made by the app so far.
Is Maddox himself getting rich off the app? Not quite, but he has made more than $680 in advertising revenue by embedding AdMob ads in the application.

"It's been much more successful than I could have ever imagined," he says. The app has been controversial, spending a lengthy time in Apple's approvals process, with suggestions that O2 and BT weren't happy with it.
