We’ve had box sets of films and TV series since there were any boxes to put them in yet it’s taken billions of downloads of a million apps before we’ve had the advantage of bundles of them.

The idea – new to the revamped App Store in iOS 8 – is that you can get four or so apps from the same developer and save a little bit of money over buying them separately. Only a little bit, but.

Go to the App Store today and you’ll see a banner ad for app bundles. Take a look.

But easily the one that leaps out at me is the Omni Group bundle. The Omni Productivity Pack contains:

• OmniFocus 2 for iPad
• OmniOutliner for iPad
• OmniPlan 2 for iPad
• OmniGraffle 2 for iPad

Currently that bundle costs £94.99 as opposed to a total of £111.93 if you bought them separately. So that’s a saving of £16.94 which is not to be ignored. But in each case this gets you the standard edition of the apps and it costs more for the Pro versions.

But look at me: I already own OmniFocus and OmniOutliner. For people like me, Apple’s borrowed its pricing model from TV series: I can “complete my bundle” for £53.01. To buy the apps I haven’t got, OmniPlan and OmniGraffle would otherwise cost me £69.98. So that’s a saving to me of £16.97.

I don’t need either OmniPlan yet or OmniGraffle maybe ever, but these are the kinds of savings the new idea brings and that’s got to be good.
