Kona

Searched 'Starbucks' from the ratings page and got five real named locations with addresses, no login needed, and the half-star claim holds up: ten distinct buttons from half a star to five in half-point steps. But picking a shop, rating it four stars, and hitting Save rating did nothing at all as a guest: no error, no login prompt, no network request even fired. So the one thing the app lets you do without an account quietly doesn't save. Visit tracking, the public profile and nearby search are all behind login and I couldn't reach any of them to check.
