Up to 10 lookups a day; no sign-up needed.
Where does the data come from?
StoRank actually searches the tracked keywords on the App Store and Google Play every day and stores the result lists. This tool only reads those stored results; it sends no new requests to the stores.
Only public searches are shown: keywords that appear in the store's own suggestion list or that more than one account tracks. A single customer's private keyword list and StoRank customers' own apps are never shown.
Searches for an app's own name (brand searches) don't count; ranks exclude ads.
