Why BYD Tracker
Any phone, any browser
A web app for iPhone and Android, and any browser on a computer or tablet. Add it to your home screen and it opens like any other app; nothing to download from an app store.
Records day and night
Your car is read from our servers around the clock, so trips and charges are still recorded when your phone is off or your browser is closed.
No ads, ever
Your data is never sold or shared with advertisers or marketers, and we never target adverts or marketing at you. You pay a small subscription instead.
Everything included
Alerts, reminders, mileage claims, statistics and sharing your car's information with a partner are all part of the £1.80 a month. No add-ons, no tiers.
Comparing apps? See how BYD Tracker compares with the official BYD app and the other efficiency apps.
Everything about your car, in one place
BYD Tracker checks in with your car every minute while you drive and every 15 minutes when it's parked, then turns the readings into the numbers you actually care about.
Real cost per mile
What each trip cost at your own electricity tariff, home or rapid charging. See it per trip, per day, per month.
Savings vs petrol
How much you've saved compared with a petrol car of your choice. Great for justifying the switch.
Automatic trip log
Each journey recorded with distance, time, average speed and energy used. Export to CSV whenever you like.
Charging history
Every charge detected and costed, with kWh added and the price you paid.
Car health at a glance
Battery, range, efficiency, tyre pressures, doors, windows and locks, all on one screen.
Reminders
MOT, insurance, tax, service and tyres, by date or by mileage, so nothing sneaks up on you.
New: works with A Better Routeplanner (ABRP)
Plan long trips in ABRP with your car's real battery level. Sign in to ABRP from BYD Tracker once and choose your car, and your battery %, speed and charging status are sent to ABRP after every reading, so your route plan always starts from where your battery really is. Included in your subscription; switch it off at any time.
Give a year of BYD Tracker this Christmas: £17
Know a BYD driver? Give them a whole year for a one-off £17. We can email it to them on Christmas morning, or send it to you to print. Buy a gift (until 31 December).
New: works with Ohme home chargers
Charge at home with an Ohme? Connect your Ohme account once and every home charge is logged with the exact kWh and cost your charger measured, instead of an estimate. You also see whether it's charging now, its smart-charging schedule and what each day's charging cost. Read-only: BYD Tracker never changes your charging. Tested with the Intelligent Octopus Go tariff. Included in your subscription.
Supported BYD models
BYD Tracker works with BYD cars that are connected to the BYD app. Fully electric models and DM-i plug-in hybrids are both supported, including fuel use and costs for hybrids.
Hatchbacks
- BYD Dolphin SurfElectric
- BYD DolphinElectric
Compact SUVs
- BYD Atto 2Electric
- BYD Atto 2 DM-iPlug-in hybrid
- BYD Atto 3Electric
Saloons & estates
- BYD SealElectric
- BYD Seal 6 DM-iPlug-in hybrid
SUVs
- BYD Seal UElectric
- BYD Seal U DM-iPlug-in hybrid
- BYD Sealion 7Electric
Other BYD models that show live data in the BYD app (such as the Han, Tang, Seal 5 and Sealion 5) should work too. Some older or early cars report less, for example no tyre pressures. The 7-day free trial is the easiest way to check yours.
Hybrid vehicles also included in reporting
Drive a DM-i plug-in hybrid? Every trip is split into miles on electric and miles on petrol, with the kWh, litres and cost of each, so you can see what each mode really costs you and how much of your driving is electric.
Every trip, electric vs petrol
Month by month
Example figures. BYD doesn't report which mode the car is in, so electric and petrol miles are worked out from the battery level during each trip. Try the plug-in hybrid live demo: no sign-up needed.
See where every mile went
Today's routes are drawn on one map, each labelled with its distance and cost. Tap any trip for its full route, speed profile and a GPX download.
- Every trip on a street map, colour-coded
- Distance and cost labelled right on the route
- Trips grouped by day and month, with totals
- Time spent at each speed: town, A-road, motorway
Maps need location, which is off until you switch it on for your car (see Private by design below).
Business mileage claims, done for you
Use your BYD for work? Tick the business journeys, add where from, where to and why, and download the month (or the whole tax year) as an Excel file ready to attach to your expenses claim. The odometer readings and miles come straight from the car, so there's nothing to write down.
- Your own car: HMRC's mileage allowance, 45p a mile, then 25p after 10,000 business miles in the tax year
- Electric company car: HMRC's Advisory Electricity Rate
- Plug-in hybrid company car: HMRC's Advisory Fuel Rate for petrol, applied by date as the rates change each quarter
- Or your employer's own rate per mile
- For company cars, see how your claim compares with what the trips really cost you
Example figures. Your employer's expenses policy decides what you can claim. See the Claims page in the live demo: no sign-up needed.

Fully charged
Know the moment the battery hits 100% so you can move the car off the charger.
Battery low
A heads-up when the charge drops below the level you choose.
Nearly home
An alert when the car comes within a set distance of a place you've saved.

Share with a partner
Give your partner their own view-only sign-in to your car's trips, charges, costs and alerts. Included in your subscription; location only if you allow it.
Private by design
Built with UK GDPR data-protection rules in mind from the ground up. Your journeys say a lot about you, so they're treated that way.
Location off until you say so
To comply with GDPR, your car's location isn't collected or shown until you switch it on for your car. If you share your car with someone, you then choose, person by person, whether they can see it. Switch it off or clear it whenever you like.
Your data is yours
Nobody else using the service can see your trips, locations or details. Download it all, or delete your account, at any time.
Encrypted BYD login
Your BYD app login is encrypted and locked to your account. It's only used to read your car's data.
Read-only
BYD Tracker never unlocks, starts or controls your car. It only reads.
Stored in London
Data is kept on Google Cloud in London. Payments are handled by Stripe; we never see your card.

Questions
Which cars does it work with?
Any BYD connected to the BYD app, including the Dolphin Surf, Dolphin, Atto 2, Atto 2 DM-i, Atto 3, Seal, Seal 6 DM-i, Seal U, Seal U DM-i and Sealion 7 (see Supported BYD models). Electric and DM-i plug-in hybrid models are both handled, including fuel costs. The free trial is the easiest way to check yours.
Is there an app to show how efficient my BYD is?
Yes, this one. The official BYD app shows your battery, range and location, but not miles per kWh per trip, cost per mile or a comparison with a petrol car. BYD Tracker does, from the same BYD login. See how the BYD efficiency apps compare.
Do I need to install anything?
No. It's a web app that runs in your browser. On iPhone or Android you can add it to your home screen, where it opens like any other app and can send notifications.
What happens when the trial ends?
Nothing is charged: there's no card on file. We email you before it ends; if you want to carry on, add a card on your Account page and it's £1.80 a month, or £18 a year, from the end of the trial. If you don't, tracking simply pauses, and your history is kept for 4 weeks in case you change your mind.
Can I cancel easily?
Yes, in a couple of clicks from the Account page. On the monthly plan you keep access until the end of the month you've paid for; on the annual plan the unused months are refunded, pro rata. Your history is kept for 4 weeks in case you come back.
Can I use it for business mileage claims?
Yes. Mark your business journeys on the Claims page and download an Excel file for the month or tax year, at HMRC's rates for your own car, an electric or plug-in hybrid company car, or your employer's own rate. See Business mileage claims.
Is this made by BYD?
No. BYD Tracker is an independent service, not made, endorsed or supported by BYD. It reads your car's data using your own BYD app login.
