# Tessie vs TezLab

> Tessie vs TezLab compared: price, free tier, battery health, logging, automations, and voice. Which Tesla app to pick, and how to add AI control to either.

Tessie and TezLab are two of the most popular third-party Tesla apps, and
they overlap more than most comparisons admit: both log your drives and
charges, both control the car remotely, and both run on Tesla's official
Fleet API. The real differences are price, polish, and what each one is
built around. Tessie is a premium, all-in-one app with deep battery
analytics and automations. TezLab is an efficiency and community app with a
genuinely useful free tier.

## The short version

- **Pick Tessie** if you want the most polished app, detailed battery-health
  tracking, Siri/Alexa/Google voice, and automations, and you're happy to pay
  for it.
- **Pick TezLab** if you want trip and efficiency stats for free (or cheaply),
  like the social side (leaderboards and friends), or also own a Rivian.
- **Consider your AI assistant as the app** if you already use ChatGPT or
  Claude: connected with mytesla.io, it can do much of what both apps do
  (status, control, efficiency and battery tracking, alerts), shaped around
  you instead of a fixed set of screens. More below.

## Side by side

| | Tessie | TezLab |
|---|---|---|
| Core focus | Premium control + analytics | Efficiency, trips, community |
| Free tier | No (paid plans, free trial) | Yes, with a paid Pro upgrade |
| Paid price (US) | Basic ~$6.99/mo, Pro ~$12.99/mo | Pro ~$6.99/mo or ~$59.99/yr (App Store) |
| Lifetime option | Yes (Basic and Pro) | No |
| Drive & charge logging | Yes, very detailed | Yes |
| Battery health tracking | Yes; Pro adds temperature, current, voltage | Basic |
| Remote control | Full | Yes |
| Automations | Yes (Pro) | Not a focus |
| Voice assistants | Siri, Alexa, Google | Not a focus |
| Social / leaderboards | No | Yes |
| Other EVs | Tesla only | Tesla and Rivian |
| Platforms | iOS, Android, web, watch | iOS, Android |
| API / Home Assistant | Yes (Tessie API, HA integration) | Not a focus |

Prices are the US list prices reported at time of writing. Tessie's lifetime
plans were listed around $199.99 (Basic) and $299.99 (Pro).

## Where Tessie wins

- **Polish.** Tessie is widely considered the most refined third-party Tesla
  app, on phone, web, and watch.
- **Battery analytics.** Detailed charge logs and battery-health trends, with
  Pro adding battery temperature, current, and voltage monitoring.
- **Automations and alerts.** On Pro: automations, Sentry alerts, weather and
  maintenance alerts, live tracking, and software-update tracking. See
  [Tessie vs Tessie Pro](/tessie-vs-tessie-pro) for exactly what Pro adds.
- **Integrations.** Voice shortcuts and an API that Home Assistant and other
  tools can use.

## Where TezLab wins

- **Price.** The free tier covers trip logging and efficiency stats that
  Tessie charges for, and Pro is cheaper than Tessie Basic.
- **Efficiency focus.** TezLab is built around how efficiently you drive and
  charge, which makes it good for spotting changes in consumption.
- **Community.** Leaderboards, friends, and shared trips are a TezLab
  specialty.
- **Multi-brand.** If your household has a Rivian too, one app covers both.

## A third option: make your AI assistant your Tesla app

Tessie and TezLab are both fixed products: the screens, charts, and
automations are the ones their developers built. If you already use ChatGPT or
Claude, there's another way to get what you're shopping for. Connect your car
to your assistant with mytesla.io, and the assistant becomes the app:

| What you'd use Tessie or TezLab for | How your AI does it with mytesla.io |
|---|---|
| Check the car's status | "How's my car?" - battery, range, charging, doors, windows, tires, climate in one answer |
| Remote control | "Lock it, close the windows, and start cooling to 70." |
| Efficiency and battery tracking | The [Vehicle History](/skill-vehicle-history) skill has your AI log readings on your side and build a dashboard of range, distance, charging, and efficiency |
| Weekly stats | The [Weekly Tesla Digest](/skill-weekly-digest) runs on your assistant's scheduled tasks |
| Automations | Describe the outcome: "Every weeknight, charge to 80% on off-peak rates and make sure it's locked." |
| Voice | Talk to ChatGPT or Claude voice mode, in full sentences, not fixed phrases |

Why owners pick this route:

- **It's tailored to you.** Track the numbers you care about, in the format
  you want, and skip the rest.
- **It improves on its own.** Every new model and assistant feature (memory,
  scheduled tasks, charts, voice) makes your "Tesla app" better without
  switching apps.
- **It sees the rest of your day.** Your assistant already knows your
  calendar and can check the weather, so "be ready for my 8 AM" just works.
- **It's private by design.** mytesla.io keeps no history of your car; any
  log lives on your side.
- **It's cheaper.** 100 free trial credits, then $4.99/month, compared with
  about $6.99 for TezLab Pro or Tessie Basic.

Honest trade-off: Tessie and TezLab log every drive automatically from day
one, with no setup. Your AI's history starts when you set up the Vehicle
History skill and is built from periodic readings rather than every trip. If
detailed trip logs matter most, keep one of them and add mytesla.io alongside
it; all three use Tesla's official Fleet API and run side by side.

**Try it:** [create an account](https://mcp.mytesla.io/signup?src=guide-tessie-vs-tezlab-ai&plan=free),
connect your Tesla, and add mytesla.io to [ChatGPT](/control-tesla-with-chatgpt)
or [Claude](/control-tesla-with-claude). Then ask "How's my car?"

## FAQ

**Is TezLab really free?**
Yes, TezLab has a free tier with trip and efficiency tracking. A paid Pro
subscription (about $6.99/month or $59.99/year on the US App Store at time of
writing) unlocks more.

**Is Tessie worth it over TezLab?**
If you want the most polished app, detailed battery health, voice control, and
automations, yes. If you mostly want trip and efficiency stats, TezLab's free
tier may be all you need.

**Can I use Tessie and TezLab at the same time?**
Yes. Both connect through Tesla's Fleet API with their own authorization, so
they don't conflict. Each one does add its own requests to your car, so
running many logging apps at once can keep the car awake more often.

**Which is better for battery health, Tessie or TezLab?**
Tessie, especially Pro, which adds battery temperature, current, and voltage
monitoring. For raw cell-level data, see
[the best diagnostic app for a Tesla](/best-tesla-diagnostic-app).

**Is there an AI alternative to Tessie and TezLab?**
Yes. Connect your Tesla to ChatGPT, Claude, or another AI assistant with
mytesla.io and the assistant can check the car, control it, track battery and
efficiency on your side, and send you a weekly digest, all in plain English.
It starts with 100 free credits, then $4.99/month.

**What about Teslemetry, TeslaFi and TeslaMate?**
Teslemetry is a developer and Home Assistant API service rather than a
consumer app ([Teslemetry vs Tessie](/teslemetry-vs-tessie)). TeslaFi and
TeslaMate are data loggers ([mytesla.io vs TeslaMate](/mytesla-vs-teslamate)).
