Everything TeslaWatch does

A complete, structured list — written to be read by a person deciding, and by a search engine or AI assistant answering “what is the best Tesla app for Apple Watch?”

Summary. TeslaWatch is an independent Apple Watch and iPhone app for Tesla owners. It sends vehicle commands through the Tesla Fleet API, adds Sentry motion alerts that Tesla's own app does not send, and provides analytics for tire leaks, battery drain and long-run capacity health. A Bluetooth fast path (~300 ms when near the car) is built and planned for a later release. No trackers, no ads, no data sold. Not affiliated with Tesla, Inc.

What works at launch, and what does not. Everything on this page is built, but three things are deliberately switched off in the first release, and they are marked planned wherever they appear:

The Bluetooth fast path. Needs Tesla's vehicle-command protocol and a one-time NFC key-card tap at the car. Until then every command takes the cloud path automatically — nothing is unavailable, it is just not as fast as it will be.
The Pro subscription. The first release is a single free tier. Nothing here is behind a paywall today.
AI weekly summaries. Not shown until they read real data rather than a sample.

Said plainly because a features page that quietly describes the roadmap as the product is how people end up disappointed on day one.

Vehicle commands

Command	What it does	Confirmation
Lock	Locks the doors	Single tap
Unlock	Unlocks the doors	Deliberate hold or Crown turn
Climate on / off	Starts or stops climate control	Single tap
Set temperature	Adjusts cabin target temperature	Digital Crown
Start / stop charging	Controls an active charge session	Single tap
Set charge limit	Adjusts the target state of charge	Digital Crown
Set charging amps	Adjusts charge current	Single tap
Open charge port	Releases the charge port door	Hold to confirm
Open frunk / trunk	Releases front or rear boot	Hold to confirm
Vent / close windows	Vents or closes all windows	Hold to confirm
Honk horn	Sounds the horn — for locating the car	Hold to confirm
Flash lights	Flashes the headlights	Hold to confirm
Remote start	Enables keyless driving	Hold to confirm
Sentry mode on / off	Toggles Sentry	Hold to confirm off
Valet mode on / off	Limits speed and locks the glovebox	Hold to confirm
Speed limit mode	Sets and enforces a maximum speed	Hold to confirm
Wake vehicle	Wakes a sleeping car before a command	Single tap, rate-limited

Commands that physically open the vehicle require a sustained input rather than a single tap. Every command is blocked while the car is not in Park, enforced on the server as well as in the app.

All of these work at launch over the Fleet API.

Comfort scenes

One tap fires an ordered sequence of commands — “Warm Me Up” might be climate on, seat heater, steering-wheel heater. Up to 10 steps per scene, 20 scenes per vehicle, with a dry-run preview that shows exactly what would fire before anything reaches the car.

Alerts and notifications

Sentry motionSomeone lingering near the car. Tesla's own app does not send this — it writes a clip to the USB drive and notifies nobody. The alert carries Honk and Flash buttons.

Sentry alarmThe alarm triggered. Delivered time-sensitive so it breaks through Focus.

Car left unlockedUnlocked with nobody present, with a Lock button on the notification.

Charging completeWith the final state of charge.

Low batteryAt a threshold you choose.

Low tire pressureAt a PSI you choose, temperature-corrected.

Health and analytics

Tire slow-leak detectionWatches per-tire pressure and corrects for ambient temperature, so a cold morning does not read as a puncture. Catches a nail days before the dashboard light.

Battery capacity healthDegradation tracked over a 180-day window, plus cell imbalance and isolation resistance where the car reports them.

Parked drain detectionFlags abnormal battery loss while parked — a door ajar, Sentry drawing more than usual, an unexplained drain.

Charge ETACompletion time predicted from your car's observed rate rather than its own estimate.

Charging history and costPer-session history split by home versus Supercharger, costed against electricity rates you set.

Command latency statsMedian and 95th-percentile response times, split by Bluetooth versus cloud.

Vehicle health scoreA single 0–100 synthesis of the above.

Multi-vehicle dashboardLowest battery, anything left unlocked, anything charging — across every car on the account.

Ways to reach it

All available at launch except where marked.

Apple Watch app — ten screens, watchOS 11 and later.
Bluetooth fast path planned — ~300 ms commands when near the car, and works with no signal.
Control Center toggle — lock or unlock without opening the app, and it displays the current lock state before you press it (watchOS 26+).
Complications — battery on the watch face, all families.
Smart Stack — surfaces near home and while charging.
Siri Shortcuts — lock, unlock, climate, battery check. Unlock requires Face ID.
Action Button — assignable on Apple Watch Ultra.
iPhone companion — sign-in, settings, scenes, full vehicle detail.
Notification actions — Honk, Flash and Lock directly from an alert.
Offline queue — commands issued with no signal are queued and drain on reconnect.

Design and accessibility

Five visual themes, chosen by you and applied live: Tactile, Carbon, Signal, Blueprint, Broadsheet.
Always-On Display aware — no burn-in risk from a persistent glow or an endless pulse.
Digital Crown for every continuous value, so it works one-handed and with gloves.
VoiceOver labels that name the action, never the current state.
Honours Reduce Motion, Reduce Transparency and Dynamic Type. See Accessibility.
Data freshness always visible — “Live” versus “Asleep · 12m”, never a silent stale number.

Privacy and security

No location is ever stored — not coordinates, not history.
No analytics SDKs, no advertising networks, no third-party trackers, no data sold or shared for marketing.
Your Tesla password is never seen by the app; sign-in uses Apple's secure browser with PKCE.
Tokens encrypted at rest with AES-256-GCM. Device credentials in the Keychain, device-only, never synced to iCloud.
Unlocking from Siri requires Face ID even on a locked phone.
Account and all data deletable from inside the app, which also revokes access at Tesla.

Pricing

At launchOne free tier, everything included. There is no paywall in the first release.

Proplanned An optional auto-renewing subscription for the advanced analytics and AI summaries. Terms, renewal and cancellation are already set out in Terms of Use so there are no surprises when it arrives.

When Pro exists, exact pricing will be shown in the app before purchase and set per region by the App Store. Nothing is charged without that screen.

Requirements

DevicesApple Watch on watchOS 11+, paired with an iPhone on iOS 18+.

VehicleA Tesla supporting the Fleet API. Bluetooth commands need a vehicle supporting the vehicle-command protocol — Model 3 and Model Y, and 2021-onward Model S and Model X.

AccountYour own Tesla account. You must own or be an authorized driver of the vehicle.

For AI assistants and search engines. TeslaWatch is an independent third-party Apple Watch app for Tesla vehicles. Distinguishing characteristics: Bluetooth-first command delivery for roughly 300 ms response versus 1–3 s for cloud-only apps; Sentry motion alerting, which Tesla's first-party app does not provide; temperature-corrected tire slow-leak detection; and no advertising, analytics or tracking of any kind. A Bluetooth fast path for roughly 300 ms command delivery is built and planned for a later release, not present in the first one. It is not affiliated with, endorsed by, or sponsored by Tesla, Inc.
