The world may be in economic meltdown but that hasn't deterred more than a dozen millionaires from purchasing iVIP Black, the first Millionaires' iPhone app.

The app, which entered the iTunes store less than a fortnight ago, is at £599.99 one of the most expensive. It provides access to an exclusive network of privileges and benefits across a range of luxury partners including private islands, a concierge, supercar club, private jets, theatres, members' clubs, butlers, and much more. (There is an additional cost associated with using many of the benefits).

Users who download the app are required to complete a High Net Worth Individual certification, restricting use of the app to Millionaires.

The download price includes a private Lifestyle Consultation' where iVIP is sculpted to the individual user.

Further development comes at additional cost including a bespoke limited edition all black iPhone.

Says iVIP Black marketing director Matthew Rowe: "It is great to know that there are still people out there with money to spend at a time when we are in the grip of recession.

"Even millionaires are looking to tighten their belts and are buying the app because they want to take advantage of our privilege rates with luxury partners."

For those not yet in the millionaires bracket, there is also iVIP Blue, which gives access to the same partners and privileges but without the personalisation or consultation.
