“Different cities use different terminology — so for example in New York you've got the MTA subway, in Chicago you have the CTA L train. Once I started adding these kind of keywords I found that downloads increased substantially.”

Use local insider vocabulary (MTA, CTA L-train) in per-city ASO

Generic terms like 'transit' lost to the way locals actually phrase it. Adding 'MTA', 'CTA L train', and local equivalents to title + subtitle + 100-char keyword field per locale drove the bulk of Mumigo's 5M downloads. Pair the keywords with per-city screenshots so each user sees their own network in the store listing.
