OBD Scope

OBD Scope is a focused, read-only OBD-II companion for drivers who want a quick vehicle snapshot and a report they can keep or share.

Use a compatible BLE ELM327 adapter to:

• Read standard RPM, speed, coolant temperature, and short fuel trim values.
• Review standard diagnostic trouble codes reported by the vehicle.
• Check emissions readiness when the vehicle provides the standard response.
• See unavailable values clearly instead of guessing or filling gaps.
• Save recent scan history locally on your device.
• Share a PDF summary or CSV data from the Android share sheet.

OBD Scope sends setup and standard read-only OBD-II requests. It never clears trouble codes, changes vehicle settings, or writes commands intended to control the vehicle. A result is informational and should not be treated as a safety certification or a substitute for a qualified technician.

Compatibility depends on the vehicle, adapter firmware, Bluetooth implementation, and supported standard PIDs. Manufacturer-enhanced ABS, SRS, transmission, and other proprietary data are not included in this release.

The free experience supports scanning. A one-time Pro unlock adds report export. There is no subscription.

Scans and reports remain on this device unless you deliberately share a report. Bluetooth permission is requested only when you start looking for an adapter.

A compatible BLE OBD-II adapter is required and is sold separately.

Designed for quick everyday vehicle checks.
