Tachwire reads your car through a Bluetooth LE OBD adapter and puts what the dashboard keeps to itself — oil and gearbox temperatures, boost, gear, a hybrid's battery, on a BMW even oil pressure — on the car's screen, laid out the way you want. When something runs critically hot, it says so out loud. A SCREEN OF YOUR OWN IN THE CAR • Tiles of any size on a grid fitted to your car's display. • Pages for the road, the track and the warm-up, a button apart. • Arrange it on the phone, start from a layout in the Gallery, or edit on the car's screen while parked. • A Live Activity on the Lock Screen, in the Dynamic Island and, on iOS 26, in CarPlay. YOUR CAR AND YOUR DRIVES • Car: your car pictured in its factory colour; tank, battery, tyres and the last drive at a glance. • Drives: a diary by day — city, highway or track, with alerts, pulls and records. • A drive's page: the route, a verdict with its reason, every reading on one time line. • Logbook: records and trends against your car's own usual; ignition timing pull and power by rpm. • Power from the torque the engine reports, never estimated. 0–60 mph or 0–100 km/h, ¼ and ½ mile, timed from the car's speed — on a closed track only. ROAD CAMERAS • Spoken alerts and a map window on the car's screen for speed and red-light cameras, section controls and low-emission zones in Spain, Portugal, Italy, the United Kingdom, Poland, Austria, Belgium, Bulgaria, Norway, the Netherlands, Czechia, Cyprus, Malaysia and Russia. France: danger zones and low-emission zones only, as French law allows. Silent where such alerts are banned. • Off until you turn it on. TRACKS • 535 tracks in 17 countries, or set your own start/finish line. • Laps by session and the gap to your best, on the car's screen too. Runs and laps only on a closed track. • Track guidance in CarPlay: on a circuit, the track map with the next turn, and your braking points once a lap is recorded. A Track map tile for any page. WHICH CARS • BMW, the deepest: G-series from 2018 and F-series, recognised from the VIN — oil temperature and pressure, gearbox temperature and gear, boost, torque and power, a plug-in hybrid's e-motor and battery, a diesel's DPF and AdBlue. • MINI (2014–2024) and the Toyota GR Supra are read the way a BMW is. • First support, readings vary by model: Mercedes-Benz, Porsche, Ford, Toyota and Lexus, RAM, Dodge, Jeep, Chrysler, Land Rover, Jaguar, Audi, Volkswagen, SEAT, CUPRA, Mazda and Honda. Renault, Dacia and Alpine are recognised. • Any other car with an OBD port: revs, speed, coolant, intake, load, often oil temperature and boost. A tile stays empty rather than show a wrong number. Make by make: tachwire.app/cars. WHAT YOU NEED • A Bluetooth LE OBD adapter: OBDLink CX (the fastest), vLinker, UniCarScan, or an ELM327 BLE clone (slower). Classic Bluetooth and Wi-Fi adapters can't connect to an iPhone. • iOS 18.4 or later and CarPlay, wired or wireless: the app reads the car only while CarPlay is connected. • No adapter yet? Choose "No adapter yet" on the first screen: which one to get, and a demo drive. READ-ONLY, PRIVATE Tachwire only reads live values: no fault codes, no coding, nothing changed in the car. No account, ads or tracking. Drives stay on the phone unless you turn sending on (encrypted, route removed; only laps on a track keep their positions). Crash reports turn off with one switch; usage data only if you agree. GPS runs only during a drive. SUPPORT TACHWIRE Everything in the app is free. Monthly coffee and Monthly burger are optional monthly subscriptions, a thank-you to the developer, with car looks: a playful picture for the Car card and your pick of its trim and colour; every figure stays your car's. Auto-renews monthly; cancel in Apple Account settings at least 24 hours before renewal. Terms of Use: tachwire.app/terms. Privacy Policy: tachwire.app/privacy.
