What Is Tessie?
Tessie is a third-party Tesla companion app built to offer more insights, control and automation than Tesla’s official app. Launched in 2021, Tessie now supports iOS, Android, Apple Watch, Android smartwatches, and web access.
It’s designed by Tesla owners, for Tesla owners, and it shows.
Key Features of Tessie
🔋 Battery Health Tracking
One of the biggest limitations of the official Tesla app is the lack of battery health visibility. Tessie solves this with real-world estimates based on your charging sessions and usage patterns. It’s a game-changer, especially for those buying or selling a used Tesla.
🧠 Automation
Automate routines like unlocking doors, pre-conditioning, or stopping charging at set times or conditions (e.g. when plugged in or departing home).
Want to auto-start Dog Mode or set your seat heaters before you leave? Tessie makes it easy.
📱 Smartwatch & Web Control
Control your Tesla from your smartwatch (including Android!) or desktop browser. Everything from window controls to Sentry Mode, all from your wrist or computer.
🧭 Detailed Trip Tracking
Track every journey in detail, including:
- Energy usage
- Driving efficiency
- Route heatmaps
- ICE vehicle savings comparison
- Telemetry from shared/lent vehicles
💸 Cost Analysis & Charge Monitoring
Track your phantom drain, charging sessions, and energy spend, broken down by kWh, charger type, and even cost estimates. If you’re using Octopus Energy’s Intelligent Go tariff, Tessie can help optimise your charging even further.
Why I Recommend Tessie
As a Tesla owner who also uses Octopus Intelligent Go, Tessie's insights into charging patterns, battery health, and smart home automation are unmatched.
The trip reports alone are worth the subscription if you’re a numbers nerd or want to prove your range!
2025 Model Compatibility
Tessie is fully compatible with the latest Tesla models, including the 2025 Model 3 Highland and the 2025 Model Y Juniper. Whether you’ve just picked up one of these refreshed vehicles or upgraded from an earlier model, Tessie integrates with all the new features and firmware updates. You’ll get complete access to trip tracking, battery health monitoring, charging insights, and more, all optimised for the newest Tesla tech.

Final Thoughts
If you want to unlock your Tesla's full potential, Tessie is an essential upgrade. With its powerful analytics, custom automation, and true cross-platform support, it’s one of the smartest subscriptions you can make as a Tesla owner.
💡 My Tessie Setup: From Paid Plan to Free Lifetime
I started on a paid Tessie plan and earned a free lifetime subscription through referrals. I use it alongside my 2021 Tesla Model 3 Long Range and Octopus Intelligent Go, mainly for charging insights and battery health tracking. Being able to monitor phantom drain and see exactly what I'm using overnight on cheap-rate electricity is genuinely useful – especially when optimising around the 7p/kWh off-peak slots.
