Ask a founder who their competitors are and you get the three apps they admire. Ask the search results and you get a different list, usually more useful.
Every tracked app now comes with suggestions: the apps ranking alongside yours on the keywords you care about, ordered by how much of your search surface they overlap. Add one in a click and it starts being tracked with the next update.
It is the Competitor Finder logic pointed at the apps you already track, and it reliably surfaces at least one app nobody had on their list that is quietly taking installs.
