Public app store top charts, a panel of publisher-shared actuals for calibration, and search interest panels
Daily chart collection, rank-to-volume modelling and monthly keyword index computation
App market and search demand data for two of the highest-spending mobile markets, including a local Android store that global trackers often miss.
Chart positions are collected daily from public store charts. Download and revenue estimates come from Seoulwave's model, which maps chart rank to volume using a panel of apps whose publishers share actual figures; for apps in the top 500, estimates are typically within 25% of reported numbers, and accuracy falls further down the charts. Search interest indices are built from a search panel and portal keyword tools and are relative indices, not absolute query counts. History starts in 2018 for charts and 2020 for search.
