Apple Fitness+ subscriptions feature over 3,000 workouts and meditations at a cost of $9.99 per month or $79.99 per year. The subscription is available in 21 countries.  Launched in late 2020, Fitness+ has become another key part of Apple’s roughly $19 billion services business, which includes Apple Arcade, Apple TV+, and Apple Music. A JP Morgan analyst reckons Fitness+ could generate $3.6 billion in revenue by 2025, up from $300 million in 2021. Also: iPhone 14 Pro vs. iPhone 13 Pro: Is the newest iPhone worth the upgrade? Apple is offering three free months of Fitness+ for customers buying a new iPhone, iPad or Apple TV.

In iOS 16.1, Fitness+ is integrated with the Fitness app via a middle tab. Also, users without an Apple TV can stream content via AirPlay to compatible third-party devices as well as all AirPlay-enabled Roku devices.  To sweeten the offer, Apple is bringing music by Taylor Swift to Fitness+ as part of an Artist Spotlight series featuring Swift’s newly released “Midnights” album.      The update will also let users share car, hotel room, and other keys in Apple Wallet using messaging apps such as Messages and WhatsApp.  The Fitness+ special offers include SilverSneakers’ offer of a free subscription from January 2023 through select Medicare Advantage plans. Target will offer a four-month free trial of Fitness+ for members of its loyalty program.
