Apple Watch and Kinni

Apple Watch can provide live heart rate while you record a Kinni run from your iPhone. The iPhone app remains the main control surface: choose the workout, start the run, stop the run, and review the session in Kinni on iPhone.

• Use Kinni on iPhone with a paired Apple Watch.
• Install Kinni on Apple Watch from the iPhone Watch app if the setup screen shows Install Kinni.
• Keep the watch unlocked and worn so heart-rate measurement can work.
• Allow Apple Health permissions when Kinni asks. Kinni requests the Apple Health access it uses for live Apple Watch heart rate and walking/running workout sync up front, so you should not need to return later just to add the usual Kinni health permissions.

1. In Kinni on iPhone, open Profile.
2. Under Connected apps & devices, tap Apple Watch.
3. If the setup screen shows Install Kinni, open the iPhone Watch app, find Kinni, and tap Install.
4. Return to Kinni and tap Allow Permissions if the setup screen asks for Apple Health access. This permission step covers the Apple Health access Kinni uses for Apple Watch live heart rate and walking/running workout import/export.
5. Open Kinni on the watch once.
6. Wait for the watch app to show a live heart-rate preview or workout-ready state.
7. Return to the Apple Watch setup screen in Kinni. If Kinni is ready, the screen shows Connection status: Ready and the Open Kinni on watch row is marked Done automatically. If the screen still asks you to finish setup, tap Refresh status after opening the watch app.

The setup screen uses the same user-facing action wording as Wear OS where possible: Install Kinni, Allow Permissions, and Open Kinni on watch. Apple Watch setup is marked ready automatically when Kinni can confirm the watch app is installed, Apple Health access has been requested or needs no further Kinni action, and the native watch connection is ready to start.

1. Open Go Run or the workout run setup screen.
2. Check Run devices for the Apple Watch card.
3. Start the Kinni run from the iPhone.
4. Keep the watch on your wrist during the run so Kinni can receive live heart-rate updates.
5. Stop the run from Kinni on iPhone when you are finished.

When live heart rate is current, Kinni can show the BPM value on the watch-ready surfaces. If the value is still measuring or unavailable, keep the watch awake, worn, and close to the phone.

Apple Watch is not a treadmill connection and does not control treadmill speed or incline. Use Kinni’s treadmill connection articles for FTMS, FitShow, or treadmill-control questions.

Apple Watch also differs from Apple Health sync. Apple Watch is the live companion path; Apple Health is the phone health store used for completed-session import and export.

• Confirm Apple Watch is paired with the iPhone you use for Kinni.
• Confirm Kinni is installed on Apple Watch.
• Reopen Kinni on the watch and keep the watch unlocked.
• If permissions show as denied or need attention, tap Allow Permissions on the Apple Watch setup screen. Kinni will guide you to iPhone Settings when Health access was denied; allow the requested Apple Health access, then return to Kinni.
• If heart rate stays unavailable, check that the watch is being worn snugly and that no other condition is preventing the watch from measuring heart rate.
