Workshop-grade
diagnostics on your Mac
The same deep EV & JLR diagnostics as the iPhone and iPad app, built for the bench — wired USB ELM327 adapters, sustained multi-hour sessions, and printable reports.
In active development
The Mac build isn't shipping yet. When it lands it will be downloaded directly from evmetrics.co.uk — and every feature is fully unlocked, with no Pro subscription. (The iPhone & iPad app is available now on the App Store.)
Built for the bench, not the pocket
A phone is perfect for a quick check in the driveway. When you're running a full diagnostic session — every ECU, hundreds of PIDs, over an hour — you want a wired connection and a big screen.
Wired throughput
FTDI / CP210x / CH340 USB ELM327 adapters push far more frames per second than BLE, with no radio contention.
No mid-scan dropouts
A cable doesn't go to sleep, roam, or lose pairing. Full vehicle scans complete without a stalled connection.
Room to work
Live sensor dashboards, CAN traffic and multi-ECU results laid out across a desktop display instead of a phone screen.
Everything the pro workflow needs
Manufacturer UDS Service 22 access to the data the dealer sees — the same diagnostic engine as the iOS app, tuned for sustained wired sessions.
Full Vehicle Scanner
Sweep every mapped ECU in the vehicle — BECM, HVAC, TPMS, TCM, E-Diff and more — and see which modules respond and which are silent. Wired USB keeps the sweep alive to the last module.
Mode $06 / EOBD Tests
On-board monitor results for every supported test ID — the same readiness data emissions testers rely on. Spot failing monitors before an MOT.
CAN Bus Monitor
Track TX/RX counters per CAN bus in real time. See which protocol is active, how many frames are positive, and switch buses — 7E0 / 7E1 / 795 headers — without disconnecting.
HV Battery Deep Scan
Pack voltage, current, state of charge, state of health, individual cell voltages and battery temperatures — from the actual BMS, not OBD gateway proxies.
Diagnostic Reports
Complete HTML reports covering all OBD modes ($01–$09): freeze frames, O2 sensors, IUPR counters, EV battery sections and NHTSA vehicle info — ready to print or share with a customer.
Workshop Checklists
Reusable checklist templates — Full Service, MOT Check, a cost-ordered Engine Diagnostic — applied per vehicle with red / amber / green on every item. Build your own and share as .evmwt files.
Fleet Cost Tracking
Track every vehicle's costs — expenses plus scheduled, recurring events — rolled into totals spent, what's due in the next 12 months and a projected annual run-rate. Exportable as .evmfleet.
iCloud Cross-Device Sync
Garage vehicle records, Workshop templates, active jobs and Fleet costs stay in step across iPhone, iPad and Mac — start a job on the phone, finish it at the bench.
VIN Decode
NHTSA VIN lookup resolves make, model, year and powertrain automatically. Vehicle identity is embedded in every diagnostic report.
Three ways to connect
Any ELM327-compatible adapter works. Wired USB is the Mac's headline connection — no proprietary hardware required.
USB Serial Mac only
Wired FTDI / CP210x / CH340 adapters. Rock-solid throughput for sustained workshop sessions.
Bluetooth LE
Pairs with any ELM327 BLE dongle. Handy for a quick read when a cable isn't practical.
Wi-Fi
TCP socket connection to Wi-Fi ELM327 dongles. Useful where BLE range is insufficient.
