Zoomy A more useful and enjoyable screen for your MG4

Everything you’ll want to know before installing Zoomy.

Compatibility, installation, privacy and servicing — answered plainly, including the ones whose honest answer is “ask before paying”.

Questions

Features in Detail

Dashboard

  • Three analog dials with red needles and a start-up sweep — tap to change what each shows: power in kW or amps on the left; speed or battery % in the centre (tap its top half to change its colour); kWh used this drive, kWh against the whole battery, battery volts or amps on the right.
  • Dial colours that mean something — green for regen, amber before the red, like a production EV. The classic green / amber / red look is a Settings choice.
  • Six live readouts beside the dials — battery %, battery kWh, range, kWh/100 km, kWh used, regen kWh.
  • kWh/100 km over the distance you choose — the last 5, 10, 20, 50, 100, 250, 500 or 1000 km; tap it to step through them.
  • Range from the car’s own figure, shown as the car gives it or adjusted by how you have been driving lately.
  • Outside and cabin temperature on one line with a 12 or 24 h clock — the outside figure from the car’s sensor, or the nearest weather station, named, when the sensor is heat-soaked.
  • Profile buttons — Warm up / Normal / Cool down, or up to seven of your own saved profiles by name.
  • Up to two of your own quick buttons — lane keeping (ELK), one-pedal, overspeed alarm, speed-limit tone, lane-warning sound, energy saving, or the next saved profile.
  • Compass band across the top corner, if you switch it on.
  • Speed offset so the gauge can be made to agree with the car’s own speedo.

Driving profiles

  • Up to ten one-tap profiles — drive mode, regen level, the cruise and traffic-jam assist settings, the speed limiter, lane keeping and its sensitivity, overspeed alarm, speed-limit tone, energy saving.
  • Climate in a profile — cabin temperature, A/C on or off, climate AUTO, heated seats and heated wheel. Or Do not apply TEMP changes, so a profile leaves the climate alone.
  • Auto-apply when you get in, chosen by outside temperature — the cold, normal and hot thresholds and which profile each one uses are yours to set.
  • Lane keeping re-asserted when you leave Park, so the car’s own reset each drive does not undo your profile.
  • Driving settings apply at any speed, the moment you tap, with no confirmation step and nothing to dismiss. Climate applies the same way.

Cameras

  • Indicator camera — the matching side camera pops up when you indicate, holds for a time you set (0–10 s), at the side or centred, with a rear-camera option.

Trips, energy and cost

  • Drive Stats page — every recent trip; tap one to see its route on a map. A charge-session log with AC and DC tagging.
  • Your own electricity tariff — off-peak, shoulder, peak and solar windows with your prices, so every cost is real.
  • Battery health estimate and a vampire-drain readout.
  • A report you copy to a USB stick as a web page — the last 7, 30 or 90 days, or everything the car still holds.
  • EV vs ICE — money saved this drive and lifetime, litres of petrol avoided, live pump prices for your state, the novated-lease FBT figure.

Map and trips

  • Full-screen map that follows the car — road, satellite and topo layers, scroll lock.
  • Trip estimator — pick or type a destination, tick towing or return, and get kWh needed, battery used and a go / no-go verdict against a 5% reserve.
  • Saved places, learned from where you actually drive.

Performance

  • G-Force — live and peak g in all four directions; 0–60, 0–100, 400 m time and trap speed, timed from the car’s own speed sensor and recorded even with the page closed.
  • Lap timer — a GPS start/finish line you place, or that snaps to a known circuit; live lap clock, how far off your best you are, lap list, mini track map.

Car

  • Tyres — pressure and temperature at each corner, colour-coded, on a car drawn in your colour.
  • Versions — your head unit’s software versions, Zoomy’s own version and the code that proves which build it is, every licence and attribution.

Screen

  • Screen saver — nine animated modes.
  • Night dimming — dims the head unit from a set time before sunset, to a level you choose.
  • Text size — three app-wide sizes.
  • Hide pages you don’t use from the swipe order; choose whether Zoomy opens on the gauges or the app grid.
  • Show or hide the Zoomy icon on the MG menus; a steering-wheel button can open Zoomy.
  • A floating “⌂ Zoomy” button over the car’s own screens to jump straight back.
  • Hide pages you don’t want on the move — a hidden page leaves the swipe order and keeps its icon on the home screen. A new install starts with four pages, the screen saver among them, already hidden.

Connectivity and privacy

  • Wi-Fi only — Zoomy never uses the car’s built-in SIM. Find and join a Wi-Fi network from inside Zoomy, and check you are online, without leaving the app.
  • Nothing leaves the car — no uploads, no account, no tracking, no cloud.
  • FORGET — one button deletes every stored location (trails, trip endpoints, home) from the car.
  • Return to factory — back everything up to a USB stick, every file read back and checked and the stick flushed, then remove the app, and restore it afterwards.
  • Android Auto and CarPlay re-plug fix at start-up, for the MG bug where a phone plugged in before boot never connects.

Before you buy

Will it work on my MG4?

Zoomy supports these cars and head units.

  • Cars — MG4 XPOWER, Long Range 77, Essence 64, Excite 64 and Excite 51. You pick yours under Settings → Your car, and Zoomy uses it for pack size and power so the range and efficiency figures suit your car rather than the XPOWER’s.
  • Head units — SWI 165, 133, 132, 131, 69 and 68.
  • Built on the XPOWER running SWI 165 — and driven in every day, so that is the combination with the most road miles behind it.

What is the technical compatibility information?

  • Infotainment System software — developed and tested against SWI 165. Some of the older SWI versions are recognised.
  • The platform — Android Automotive 9 on the factory 1280×480 MG4 Infotainment System.

What does it cost, and is it a subscription?

$45 per car, once.

  • Not a subscription — you are buying the app, not renting it.
  • No renewal — it keeps working, including after I stop updating it.
  • Nothing to cancel — there is no account and no recurring charge to stop.

Installing it

How hard is the install?

About 10 minutes at a computer and in the car, once.

  • Fiddly the first time and never again.

Do I need a computer?

Yes, briefly — the app reaches the car on a USB stick formatted FAT32. No cable to the car, nothing to install on the computer, about 10 minutes all up:

  • Use a small stick — 32 GB or less. Most are FAT32 out of the box, and Windows will not offer FAT32 on bigger ones.
  • Windows: right-click the stick in File Explorer → Format… → pick FAT32 → start.
  • Mac: Disk Utility → select the stick → Erase → format MS-DOS (FAT).
  • Copy Zoomy onto it — drag the APK from your download onto the stick. That is the whole step.
  • Formatting wipes the stick — use an empty one, or copy anything off it first.

Does it update itself?

No. Zoomy never updates itself, and it has no way to.

  • Nothing checks, downloads or installs by itself. There is no background check and no automatic download — the car you drive away with is the car you keep until you decide otherwise.
  • New versions reach you by email, with the same link from your purchase. It keeps working for every release.
  • The same short job as the first install — onto the USB stick, and over the top of the old one.
  • Your trips, charges and settings all carry over.

Living with it

Where does Zoomy appear once it is installed?

On the car’s own home screen.

  • A moveable shortcut next to Apple CarPlay and Android Auto.
  • Easy to reach — no hunting through menus.
  • You can move it if you would rather it sat elsewhere.
  • Or remove it entirely — one setting hides that shortcut and the small floating Zoomy button that sits over the car’s own menus, so the car looks exactly as it did before you installed anything.
  • The left ★ steering-wheel button is the other way in — hold it to open Zoomy, and hold it again from anywhere else to come straight back to it. A setting picks which side, so if the left one is not the one on your car, use the right. That is what makes removing the shortcut a real option rather than a way to lose the app.

How do I give it the internet?

Your phone’s hotspot, or your home Wi-Fi.

  • On the car: Settings → Wireless network.
  • Pick the network and enter the password — exactly as you would on a phone.
  • The car remembers it.
  • That connection is what the internet pages use — maps and fuel prices.
  • Without it, everything that reads the car still works — gauges, tyres, trips, charges and the 0–100 timer.

Does it use my car's mobile data?

No. Nothing at all.

  • Everything Zoomy fetches goes over Wi-Fi.
  • Built in, not just promised — every request Zoomy makes is checked first, so it cannot slip onto the car’s own mobile data. Settings → Internet turns Zoomy’s internet use off altogether.
  • None of it touches MG’s built-in eSIM — not maps or updates.

What data does Zoomy see, and where does it go?

It reads what the car already knows, and what it learns stays on the car.

  • From the car: speed, battery, tyre pressures and temperatures, gear and the odometer.
  • From GPS: position, for the map and the lap timer.
  • From public feeds over Wi-Fi: fuel prices and map tiles.
  • Every network call is a read-only request to a public feed. Like any map app, those carry the car’s rough position so the feed knows which patch of map to send back.
  • Your trips, charges and GPS trails stay in the app’s own storage.
    • They come off only when you tap an export — the Drive Stats report, or the backup Return to factory writes before it uninstalls. Nothing is written to a USB stick on its own.

Does it work without a signal?

Yes — most things work without a signal. The exceptions are the pages whose job is to fetch something from outside the car.

  • Keep working offline: gauges, tyres, energy, the acceleration timer and profiles.
  • Need Wi-Fi: maps and live fuel prices. Fuel falls back to a typical price so the running-cost comparison still works.

Will it affect my warranty?

It does not flash or modify the car’s firmware.

  • An app, not firmware — nothing is flashed and nothing is unlocked.
  • It writes the same settings the car’s own menus write and simply automates them.
  • There is one button for exactly that in Zoomy’s Functions page — Functions → Return to factory.

Does CarPlay or Android Auto still work?

Yes, exactly as before.

  • Zoomy is an app on the home screen next to them.
  • It does not sit in front of them, replace them, or route anything through itself.

Removing Zoomy, and the car itself

How do I take Zoomy off the car?

There is one button for exactly that: Functions → Return to factory.

  • It writes everything to a USB stick — every trip, every charge session, your settings and profiles.
  • It reads all of that back to check it before going any further.
  • It flushes the stick and tells you when it is safe to pull out. The stick is then the only copy.
  • Only then does it remove itself.
  • If the check or the flush fails, nothing is removed.

Does removing Zoomy change my car?

No.

  • Those settings live in the vehicle, not in the app — drive mode, regen, lane keep, AEB and the rest.
  • Whatever they were set to when you removed it is what they stay.

Can it damage anything?

  • It writes the same settings the car’s own menus write.
  • Incorrect settings may affect how the car behaves, and you use it at your own risk.
  • Nothing here is endorsed or supported by MG Motor or SAIC.

Safety

Does anything arrive locked, or need a code?

Zoomy is fully working the moment it starts.

One thing can refuse on its own: on a firmware Zoomy has not been measured against, no vehicle setting is written at all. That check has no switch.

Can I change how the car drives while I am driving?

  • Yes, straight away. Drive mode, regen, one-pedal and the driver-assistance settings apply the moment you tap a profile, at any speed.

Lane keep switching itself back on

  • The car turns lane-departure assistance back on at the start of a drive, whatever you set last time.
  • Zoomy puts the profile’s setting back when you leave Park. That one happens on its own rather than because you asked at the time — off, unless the profile says otherwise.
  • Off unless you say otherwise. A profile you never touched turns lane keep off at every start and keeps it off for the drive. Pick Alert, Assist or Emergency under the profile's ADAS chip to have it on, or LEAVE to let the car decide.
  • Lane keep off is the one opinion Zoomy has of its own. Every other assistance setting follows what you put in the profile, or is left alone.

Can I use the screen while I drive?

Using the screen while you drive is your responsibility. Road rules differ from state to state and they change, so check what applies where you drive.

Why do some pages not come up when I swipe?

A new install starts with four pages out of the swipe order, the screen saver among them. None of them helps you drive, so you do not swipe into one by accident; their icons stay on the home screen for when you are stopped. Settings → Hide pages changes the list whenever you like, and an update never changes what you have set.

Security

How is my payment handled?

  • By Stripe — Stripe is one of the largest payment companies in the world, used by millions of businesses including Amazon, Shopify and the Australian Government's own services. It is a private US company, independently audited, and certified to the highest level of the card industry’s security standard (PCI DSS Level 1).
  • You pay on Stripe’s page, not mine — card details are typed into Stripe’s own checkout, and Zoomy’s site never touches them.
  • This site never sees a card number, and could not store one if it wanted to.
  • No order database — Stripe’s dashboard is the record of sale.
  • No account and no password — there is no credential store to be breached.

Privacy

What does Zoomy send about me or my car?

Nothing, zero, not a single byte.

The full list of things Zoomy does not do

  • No account, no sign-in, no password.
  • No analytics, no tracking, no advertising ID.
  • No uploads of any kind.
  • No camera recording.
  • No third-party analytics or advertising libraries.
  • No remote control.
  • Your VIN never leaves the car.
  • MG’s built-in eSIM is never used for app data.
  • No copy protection phoning home.

So what does Zoomy use the internet for?

Reading, not reporting.

  • Pump prices — today’s board prices for your state, so the running-cost page compares your charging against real petrol rather than a guess. There is no coverage in South Australia, Tasmania or the Northern Territory; those states fall back to a typical price, and the comparison still works.
  • Map tiles — OpenStreetMap and the satellite and topographic layers.
  • New Zealand rain radar — in New Zealand, the Rain page shows MetService’s radar pictures, passed on unaltered by zoomyzoom.com.au. This app incorporates information made freely available by MetService. Despite this, MetService is not associated with, and does not endorse, Zoomy or how this app uses MetService information. Radar: MetService – Te Ratonga Tirorangi, CC BY 4.0.
  • Addresses and distances — turning a typed address into a place, and a place into a driving distance.
  • Nothing else.

A bit more detail:

  • Some requests include roughly where the car is — because that is what is being asked for. To draw a map, the map service has to be told which part of the map to send.
  • They go to the same public services your phone uses.
  • They carry no name, no account, and nothing that identifies you or the car.
  • They are requests for information, not reports about you.
  • The network is used only where the screen shows something from outside the car — maps and pump prices. Everything the car itself measures is read from the car.

What does this site see when I pay?

  • Payment is handled entirely by Stripe’s hosted checkout.
  • This site never sees a card, stores no name or email, and sets no tracking.
  • Your receipt comes from Stripe, and the email address on it is the same one that answers support.

The licence, and the archive

One licence per car — how is that enforced?

It is not enforced at all — it is honesty-based, and priced so honesty is easy.

  • No activation, no key to type, nothing phoning home.
  • One licence covers one car at a time.
  • Two cars at once means two licences.

Where do the MG4 notes come from?

  • Public sources only — every one linked on its own entry, so you can go and read the original.
  • Owner reports, not MG statements and not advice.
  • Check your handbook and your dealer before acting on any of them.
  • Nothing from private or closed groups.

Who am I buying from?

  • Three Australian developers — not a company and not a dealer. The work is published as Zoomy (zoomyzoom.com.au).
