I never paid a single cent in this app and yet the app is perfectly enjoyable. I've used it since 2019. What's wrong with freemium? I don't need extra features and the free features are good enough for me.

The thing I specifically paid for (that Google Maps doesn't seem to offer) is answering the question "what transit lines/stops are nearby and how soon will a service arrive at the stop?" Last I looked they limit the number of lines shown in this way for freemium users.

If you're just putting in a destination and getting a fastest route (much like you'd do in Google Maps), then I didn't see much benefit to the premium version.
