The official BYD app is good for the basics: battery level, range, where the car is, tyre pressures and remote controls. What it doesn't show is how efficient each trip was, what it cost, or how that compares with a petrol or diesel car. For that, owners use a companion app that signs in with the same BYD login.
From each app's own website or store listing, checked in October 2026. Prices and features change, so check before you buy. BYD Tracker is our own service; the others are independent of us.

Where the others are ahead: BYD Connect and LFPDrive can send remote commands (lock, climate); LFPDrive and BYD DM Stats are free. BYD Tracker is read-only and doesn't control the car. Like BYD Connect, BYD Tracker sends live data to A Better Routeplanner (ABRP) and estimates battery state of health.
Connect your BYD app login once. From then on every trip is recorded with its distance, energy used and miles per kWh, every charge with what you paid, and every month is summarised with your cost per mile and the saving against the petrol car you chose. Efficiency is shown against the outside temperature too (Met Office weather), so a winter dip doesn't look like a fault.
Your dashboard also rates your recent efficiency with a rosette: 1st place from 4.0 miles per kWh, 2nd place from 3.7 and 3rd place from 3.5. It's an easy way to see how your driving and the weather are affecting your car, and something to aim for.

Yes. The official BYD app shows your battery level, range, location and tyre pressures, but it doesn't keep a history of efficiency per trip, what each trip cost or how that compares with a petrol car. Companion apps such as BYD Tracker sign in with the same BYD login and work this out for you.
Just the email or phone number and password you use for the BYD app. BYD Tracker reads your car from its servers every minute while you drive and every 15 minutes when it's parked, so trips are recorded even with your phone off. There's nothing to plug into the car.
Yes. For the Atto 2 DM-i, Seal 6 DM-i and Seal U DM-i, BYD Tracker splits each trip into electric and petrol driving and shows miles per kWh and miles per gallon, with the cost of each.
You choose a comparison car (its miles per gallon and the petrol price), and every trip shows what the same journey would have cost in it, next to what your BYD cost at your own electricity prices, home or public.
No. BYD Tracker is a web app: open byd-tracker.uk on your phone and add it to your home screen, where it opens like any other app and can send notifications. It works on iPhone, Android and any computer.
Yes. The live demo shows every page for an electric and a plug-in hybrid BYD with real data, without an account. When you're ready, the free trial is 7 days with no card needed.
