RevDash

RevDash is a live OBD-II dashboard for Android. Plug in a Bluetooth ELM327 adapter, connect once, and read engine data on a dark gauge grid that keeps polling in the background.

WHAT YOU NEED

• An ELM327-compatible Bluetooth Classic or BLE adapter

• A vehicle that speaks generic OBD-II (powertrain)

• Android 8.0 or later

FEATURES

• Live gauges: RPM, speed, coolant, throttle, load, battery voltage, and other Mode 01 PIDs your ECU reports

• Custom dash: add, remove, drag, and resize tiles; each vehicle profile keeps its own layout

• Connection that explains itself: one-tap reconnect, adapter bound to the vehicle profile, protocol hint, and a diagnostics screen that separates “Couldn’t reach adapter” from “Adapter OK — no ECU”

• Check-engine workflow: stored, pending, and permanent codes, freeze frame, generic SAE titles, clear only after you confirm

• Charts — live traces with 15s to 5m windows

• Trip CSV — GPS + OBD rows you save to a file you can open

• Backup — export and import vehicles and layouts as a zip

• Themes — Night, Day, OLED, Midnight; metric or imperial; keep-screen-on

WHAT REVDASH DOES NOT DO

• It does not read ABS, airbags, or body modules on generic OBD-II

• It does not write to the ECU or run actuator tests

• It is not a shop scan tool and not affiliated with any vehicle maker

PRIVACY

Bluetooth talks to your adapter. Location is used to scan Bluetooth on some Android versions and to stamp GPS on trip logs. Readings, layouts, and logs stay on your device. No account. No ads.
