Apple announced Workout Buddy at WWDC25 on June 9, 2025. Built into the Apple Watch Workout app through Apple Intelligence, it turns workout data and fitness history into spoken, personalized encouragement. The original watchOS 26 version has an important limitation: it requires a nearby Apple Intelligence-compatible iPhone and Bluetooth audio.

Apple later announced broader Workout Buddy support for watchOS 27, including Spanish, additional fitness data, and operation without the iPhone nearby. Those changes belong to the later update, not the original WWDC25 launch.

What Apple announced at WWDC25

Workout Buddy is a voice-based workout companion integrated into the Apple Watch Workout app. It is designed to provide motivational observations while you exercise, rather than act as a general-purpose chatbot or a complete digital personal trainer.

Apple says the feature uses Apple Intelligence to analyze information from the current workout alongside relevant fitness history. Its spoken feedback may refer to metrics such as heart rate, pace, distance, Activity-ring progress, milestones, and performance in previous workouts. The exact comments are generated dynamically, so promotional examples should not be treated as a fixed catalog of guaranteed prompts.

The voice-generation system was built using voice data from Apple Fitness+ trainers to create an energetic workout-oriented delivery. That does not mean an Apple Fitness+ subscription is required.

Apple describes Workout Buddy as motivational software. It is not a medical adviser, diagnostic tool, certified personal trainer, injury-management system, or replacement for professional coaching.

Apple’s announcement describes the feature and its data sources.

How Workout Buddy works

  1. You start an eligible workout in the Workout app.
  2. The Apple Watch records live information such as pace, heart rate, distance, and progress.
  3. Workout Buddy combines that session data with relevant historical fitness information and milestones.
  4. Apple Intelligence generates a short observation or encouragement.
  5. The result is delivered through connected Bluetooth headphones or, in Apple’s later watchOS 27 description, compatible Bluetooth speakers.

This is better understood as personalized spoken feedback than as continuous natural-language conversation. Apple has not presented Workout Buddy as an unrestricted back-and-forth AI coach, nor as a system that creates detailed training plans, nutrition advice, recovery programming, or injury-aware exercise prescriptions.

Workout types supported at launch

The original watchOS 26 announcement listed:

  • Outdoor Run and Indoor Run
  • Outdoor Walk and Indoor Walk
  • Outdoor Cycle
  • HIIT
  • Functional Strength Training
  • Traditional Strength Training

Users should not assume that every Workout app category is eligible. Swimming, rowing, yoga, Pilates, and other activities were not included in Apple’s initial list.

Compatibility: watchOS 26 versus watchOS 27

These requirements changed between Apple’s original announcement and its later watchOS 27 announcement. A watch can be eligible for a watchOS update without necessarily meeting all the requirements for Workout Buddy.

Requirement Original watchOS 26 implementation Announced watchOS 27 update
Apple Watch Apple Watch Series 6 or later, Apple Watch SE (2nd generation), or any Apple Watch Ultra, subject to the feature’s separate Apple Intelligence requirements Apple lists Apple Watch Series 9 or later, Apple Watch Ultra 2 or later, and Apple Watch SE 3 for the updated Workout Buddy experience
iPhone An Apple Intelligence-compatible iPhone nearby Apple says the updated Workout Buddy can operate without the iPhone nearby, although a paired Apple Intelligence-enabled iPhone remains part of the broader platform requirements
Audio Bluetooth headphones Bluetooth headphones or speakers
Language Supported English locale English or Spanish, with the device and Siri language set appropriately
Workout Specific run, walk, cycle, HIIT, and strength workouts Check Apple’s current support information for the applicable release

For general watchOS 26 compatibility, Apple listed Series 6 or later, Apple Watch SE (2nd generation), all Ultra models, and an iPhone 11 or later running iOS 26. But that is not the same as Workout Buddy compatibility: the original feature’s nearby phone had to support Apple Intelligence.

Apple’s later announcement of watchOS 27 expands the supported hardware list for the updated feature. It described those changes as coming in the fall, so readers should check the release status and Apple’s current requirements before treating every watchOS 27 capability as available on their device.

See Apple’s watchOS 26 announcement and watchOS 27 Apple Intelligence announcement for the version-specific hardware details.

Does Workout Buddy work without an iPhone?

On the original watchOS 26 version, no. Apple required an Apple Intelligence-supported iPhone nearby. A cellular Apple Watch should not be treated as an automatic substitute for that requirement; cellular connectivity and Apple Intelligence compatibility are separate matters.

Apple later said that the watchOS 27 update can let Workout Buddy operate without the iPhone nearby. That is a significant change, but it must not be retroactively attributed to the WWDC25 launch.

Apple later announced Spanish support for the watchOS 27 update and said the device and Siri language must be set to English or Spanish. Availability can vary by region, language, software release, and local rules. Consult Apple’s watchOS feature-availability page rather than assuming worldwide access.

How to use Workout Buddy

  1. Update the iPhone and Apple Watch to software releases that support the feature.
  2. Make sure Apple Intelligence is enabled on the compatible iPhone when using the watchOS 26 implementation.
  3. Pair compatible Bluetooth headphones; for the later watchOS 27 version, Apple also refers to Bluetooth speakers.
  4. Open the Workout app on the Apple Watch.
  5. Select a supported workout, such as Outdoor Run, Indoor Walk, HIIT, or Traditional Strength Training.
  6. Start the workout.
  7. Use the Workout app’s audio controls to enable or adjust spoken feedback where available.

Apple’s exact controls and labels can vary by watchOS release and language. Its Workout Buddy support guide provides the relevant use path for watchOS 26.

If Workout Buddy does not appear or speak

  • Check the workout: The selected activity may not be in the supported launch list.
  • Check the iPhone: Under watchOS 26, the paired iPhone must support Apple Intelligence and be nearby. An older iPhone can prevent access even when the watch can install watchOS 26.
  • Check software: Update both devices to compatible releases.
  • Check audio: Reconnect the Bluetooth headphones or speaker and confirm the Apple Watch is sending audio to it.
  • Check language: Device and Siri language settings must use a supported language or locale.
  • Check availability: The feature may not be offered in the user’s region.
  • Check expectations: Standalone operation applies to Apple’s announced watchOS 27 update, not the original watchOS 26 implementation.

Is Workout Buddy free?

Apple presents Workout Buddy as part of watchOS rather than as a separately priced feature or subscription. There is no separate Workout Buddy fee identified in Apple’s announcement. Apple Fitness+ is also not established as a requirement; its trainers’ voice data helped build the voice-generation system, but Workout Buddy and Fitness+ are separate offerings.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Fitness+ may still appeal to users who want instructor-led classes and structured content. It should be considered an optional companion service, not a prerequisite.

Privacy and safety

Apple says Workout Buddy processes relevant data privately and securely with Apple Intelligence. That is Apple’s stated privacy position; it should not be expanded into unsupported claims about every aspect of data retention, cloud processing, or model architecture.

The feature can use sensitive health and workout information, so users should review their device settings and Apple’s current privacy documentation. More importantly, motivational feedback should not drive high-risk training decisions. Do not use it as a substitute for medical advice, a qualified coach, or a clinician’s exercise recommendations.

Should you buy an Apple Watch or iPhone for it?

For most people, Workout Buddy alone is not a strong reason to buy a new Apple Watch or iPhone.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Already own a compatible watch and iPhone: Try the relevant software update first. The feature is an incremental motivational tool, not a wholly new training platform.
  • Own a watch that supports watchOS 26 but an older iPhone: The iPhone may be the real compatibility barrier. Upgrading a phone solely for spoken encouragement is difficult to justify unless you also want its broader Apple Intelligence features.
  • Want workouts without carrying the iPhone: Check the specific watchOS 27 model, software, language, and release requirements. Do not assume watchOS 26 provides standalone Workout Buddy.
  • Want structured training: Compare Workout Buddy with services such as Apple Fitness+, Garmin Coach, Nike Run Club, Strava, or Peloton based on coaching depth, platform compatibility, standalone use, subscription requirements, workout coverage, and privacy model.
  • Need spoken audio: Confirm that your Bluetooth headphones or speaker work with the watch before buying anything. AirPods are not identified as mandatory by Apple’s launch wording.

Apple’s Watch and iPhone buying pages are the appropriate places to check current hardware options. Prices and Fitness+ subscription costs vary by market and should be checked directly before purchase.

The verdict

Workout Buddy is an interesting use of Apple Intelligence: it makes ordinary workout announcements more personal by combining live metrics with fitness history and delivering generated encouragement through Bluetooth audio. Its value is greatest for Apple Watch owners who want hands-free motivation without joining a full coaching program.

But the launch version was not watch-only AI. Under watchOS 26, it depended on a nearby Apple Intelligence-capable iPhone, supported only selected workouts and English locales, and required Bluetooth headphones. Apple’s later watchOS 27 announcement addresses some of those limitations with Spanish, more fitness data, and iPhone-free operation. Those version differences—and the gap between motivational prompts and genuine coaching—are the key facts to understand before upgrading.
