App Annie acquired AppScotch, a provider of market data and in-app advertising which it says “offers users greater transparency into mobile advertising”.

“The exciting news shows how we continue to strengthen our position as the most trusted provider of app data and insights in today’s evolving app economy,” the company said.

This is its third acquisition in two years — it acquired mobile analytics firm Distimo in 2014 and mobile measurement company Mobidia last year.

“We are always looking for technologies and talent that enhance our products and mission,” said Bertrand Schmitt, CEO and co-founder.

“The AppScotch team shares our passion for apps and has developed some exciting complementary technology,” he added.

Currently, App Annie’s ‘Intelligence’ product includes “granular app download, revenue, demographic, usage and engagement estimates” for every major mobile app.

Its next major release will be ‘Marketing Intelligence’, aimed to inform on all aspects of mobile advertising, marketing and monetisation strategy.

Last month, App Annie added ten advertising network partnerships including Yahoo Gemini, Leadbolt, MobileCore and Aarki to its ‘Advertising Analytics’ solution, which now supports more than 35 advertising platforms, including Facebook and Tapjoy.

The product aims to give developers a “complete picture” of their advertising performance.

Back in January, App Annie closed $63 million in financing, with majority equity investment led by Greenspring Associates and participation from existing investors including Sequoia Capital.

In November 2015, it was ranked tenth on Deloitte’s 2015 Technology Fast 500 list, posting 5,383 per cent revenue growth from 2011 to 2014.
