App market data company. Renamed data.ai in 2022, bought by Sensor Tower in 2024.
App Annie renamed itself data.ai in February 2022, and Sensor Tower bought data.ai in March 2024. appannie.com now redirects to a data.ai login page headed "We've Been Acquired by Sensor Tower."
App Annie sold mobile app market data, a product it launched in 2010. With the rename it said it would combine consumer and market data with AI, and it signed a reseller deal with Similarweb for combined mobile and web data. When Sensor Tower announced the deal, it said the data.ai platforms would stay available as standalone products for now. Today the data.ai site is only a login page that calls itself "a Sensor Tower company."
Bottom line: for the kind of app download, revenue and ranking data App Annie was known for, go to Sensor Tower. Existing data.ai customers were told to contact their account director.
App Annie launched its mobile market data product in 2010 and sold estimates of how apps perform.
