Track all my kid's soccer games. Does a nice job of handling multiple players/teams under a single app (any busy parent will appreciate this!) and you can subscribe so it all integrates (and updates) on your normal calendar.
Really nice UX for podcast listening. Love the integration with the Apple Watch - any time a part comes up I want to skip, I raise my Apple Watch and it has skip forward/skip back immediately available if a podcast is playing.
International data including at no additional charge (and not rate-limited like Verizon & AT&T) and secure to prevent SIM-swapping attacks (you need access to your Google account to make any changes, even if the changes are over the phone).
