W3i, the in-app offer exchange provider, released a report on December 6th showcasing recent trends in mobile app monetization. The W3iNSIDER Report breaks down data from its hundreds of game developer partners and 66 million monthly active users across iOS and Android.The data shows that smaller microtransactions ($0.99-$1.99), long thought to be the backbone of the freemium model, actually contribute significantly less revenue to mobile games than more expensive in-app purchases that range from $9.99 to $19.99.

When surveying the in-app purchase price points and how they contribute to the overall revenue of a sample of games, W3i found that, on average, 47 percent of total revenue comes from purchases costing $9.99 to $19.99. Smaller purchases from $0.99 to $1.99 only contribute an average of six percent to total game revenue.

The freemium model emerged as the foremost business model in mobile gaming with premium and subscription business models declining. The freemium model is built on the back of microtransactions with gamers spending a dollar or two to unlock virtual goods.
