“habit tracker” is too hard. Start with “streak tracker”: its #1 app has only 215 ratings. Grit buys the search ad and runs Meta ads too.

An agent asks Asonix which keywords a habit app should target, checks who ranks, who buys the search ads, and their Meta ads, then adds the best two to the workspace.

Everything in Asonix, one question away.
