There are myriad tools available for researching and managing ASO strategies, most of which encompass a common set of features, such as showing an app’s listing, category rankings, keyword rankings, download estimates, and keyword research like search or difficulty scores. The most common tools include App Annie, Sensor Tower, TUNE (formerly MobileDevHQ), Mobile Action and Searchman.

From our experience, we’ve found the most accurate ranking and keyword results from Mobile Action. App Annie is one of the most well-funded tools with the biggest dataset and the best keyword search preview UI, however, it does not provide much in the way of. TUNE and Searchman both have many unique and useful features, like capturing significant, store-wide changes in rankings (TUNE), or optimizing keyword density in an app’s listing (Searchman), yet both often struggle with data accuracy.
