As of Jan. 16 2013, Facebook no longer reports figures rounded to the nearest ten-thousand for MAU and DAU. Instead, Facebook now reports MAU and DAU in tiers as well as each app´s overall ranking.
Therefore, please be advised that figures for MAU and DAU provided on this site are estimates based on data published by Facebook, information provided by individual developers, as well as past and present trends.
Estimates for the top 20 apps - though somewhat accurate - may significantly deviate from the true values and should therefore be interpreted with caution. Our team is fully committed to constantly refining our estimation method in order to provide the most accurate figures possible.
