If we were to tell you downloading the app 'Kendall & Kylie' could help the environment, you'd have a right to be suspicious.
Except for a period of ten days, each of these apps -- plus 23 more -- will be doing exactly that.
The aim of the campaign, which kicks off on Friday, 15th April and runs to Monday, 25th April, is to raise both awareness and funds for the organisation via the download of one (or more) of 27 specially selected apps during the 10-day period. 100 percent of the proceeds app purchases -- as well as In-App purchases -- will go toward WWF’s global conservation work and mission to "reduce the most pressing threats to the diversity of life on Earth."
"We are super excited to have developers from all around the world participating," Oliver Schusser, Vice President of iTunes International, told The Huffington Post Australia.
"We have developers from the US, Canada, Finland, Argentina, Japan, Russia and Spain, to name a few, and we are also so excited to have a fantastic app from Australia's Savage Interactive -- [sketching, painting and illustration app] Procreate and Procreate Pocket.
"We love the developers, who are based out of Hobart, Tasmania, and they really are a perfect fit for this project. For the campaign they have developed an 'Earth brush set', which is basically an exclusive set of brushes inspired by the natural world, and handmade by Kyle T. Webster, which we are just hugely excited about."

As for how the 27 apps were selected, Schusser says it was a case of reaching out to "the best of the best" as well as finding developers willing to creative exclusive content within each app suitable to the campaign.
"We wanted to find the best partners possible, but also who would fit to the cause, not only in the apps themselves but the in-app purchases," Schusser said.
"The core themes of WWF centre around forest, ocean, water, wildlife and the threats to food and climate. We wanted 27 apps and, specifically the exclusive additions to those apps, to be centred around these themes."
When asked what it was about, say, 'Kendall and Kylie,' that resonated with WWF's core themes, Schusser pointed out one of the core aims of the campaign -- to raise awareness -- could only benefit from apps with a large and devoted following.
"Our number one focus is awareness," Schusser told HuffPost Australia. "And obviously apps like that do have a massive following and for [Kendall and Kylie] to help spread the word about this cause -- I would argue it's a great addition."
Indeed, as part of the campaign the app boasts players can "participate in a new in-game quest and event supporting water conservation, while earning ocean conservation-themed clothing, accessories and more, through the purchase of unique water droplets. Plus, players can take and share selfies inside the exclusive WWF-branded selfie booth."
But back to our Australian developers from Tassie.
"The team and I were really proud of this one," Schusser enthused. "It's really such a great fit. We love the developer. They operate out of this really tiny shop out of Tasmania and are really passionate about local environment. It was obvious they were an instant fit to the cause.
"The idea of creating these exclusive 'Earth brushes' in addition, we thought was really beautiful."
