A good keyword gets searched often and isn't owned by apps with huge rating counts. Here's the process, and a tool to run it.

Start with what your app does, in the words a user would use. Add the words competitors put in their names and subtitles. Then type your main keyword into the search tool and read the related searches.
Search each idea in the tool. Popularity shows how likely people are to search it. Difficulty shows how strong the apps ranking for it are. High popularity with low difficulty is what you want.
Don't chase the biggest term. Habit tracker is searched a lot, but the top apps have well over a hundred thousand ratings. A more specific phrase sends fewer users and is a lot easier to win.
Open the row and look at the ratings, the star average and the last update of each app. If most of the top ten have few ratings, low stars or no update for a year, the keyword is open.
Apple indexes the app name, the subtitle and the hidden keyword field. Put your strongest keyword in the name and a second one in the subtitle. Fill the keyword field with the rest, separated by commas and no spaces, and don't repeat a word across fields.
Apple's own search popularity score for each keyword, by store or worldwide.
Example: Apple search popularity, US store, October 2026.
Seven signals add up to one potential score. Turn any of them off and it updates immediately.
Example: four signals on, two switched off.
Open a keyword to see its top 10 apps with ratings, stars and last update date.
Example: ratings of apps ranking for "pool calculator", US store, November 2026.
Related searches are a click away, so one good keyword becomes a list.
Example: related searches for "meditation timer".
