Qapital
Qapital is a personal finance mobile application (app) for the iOS and Android operating systems, developed by Qapital Inc. The app is designed to motivate users to save money through a gamification of their spending behavior. It moves money from a user's checking account to a separate Qapital account, when certain rules are triggered. Its database is used by psychology professor Dan Ariely to study consumer behavior. Qapital was released in Sweden in 2013, then in the US in early 2015.
