The 0870 iPhone application - which finally made its way onto Apple's iPhone App Store at the end of September - has saved its 92,000 users a total of more than £250,000 in just a fortnight, according to the program's writer. (If you're behind the game on this one, see our previous post.)
Simon Maddox, who wrote the application - which lets people look up cheaper geographical alternatives to "national rate" numbers with the 08 prefix - has tracked the number of downloads and the amount of advertising revenue from his application, and found the results far more encouraging than he could have expected.
If you're just here for a summary, here goes: 91,722 downloads; £267,987.54 saved! $680.82 made in ad revenue
Yes, you read that right. In the two weeks the app has been released, it's saved UK consumers over a quarter of a million pounds! Pretty awesome! How do I calculate that?
Easy: Take the number of successful conversions, multiply it by the average saving per minute (35p), and then multiply it by an average call length - I used 5 minutes.
Impressive, eh? He also provided a graph of the pattern of downloads. We've taken the liberty of adding in the advertising revenue. (He gets that. It totals $680.73 - about £425 - for the period.)
That's got to be a big win for everyone. Except, perhaps, the companies using 08x numbers (apart of course from 0800) - and the telecoms networks that have shared from the extra revenue those numbers take off you, the caller.
