SwiftKey co-founder and CEO Jon Reynolds said: This is the start of an incredibly exciting phase for us as a business. We have made the decision to go free to better enable everyone, everywhere, to use SwiftKeys market-leading technology without payment being a barrier. We’re focused not only on reaching more users with our powerful technology, but on building great content and features to engage them.
The decision is part of a trend among app developers towards freemium models, where the basic app is provided for free, funded by in-app downloadable content such as custom themes.
