BLUEPRINT SCANNER COMPANION
Put the diagnostic evidence workflow on your phone Install Blueprint Diagnostics from the browser, open it from a home-screen icon, connect a compatible Bluetooth Low Energy OBD adapter for read-only standardized data, and keep captured review sessions available on that device.
BLUEPRINT ON YOUR PHONE
Download it like a regular app Get a full-screen app icon for faster VIN scanning, diagnostics, Mechanic AI, and tuning-log review. No App Store is needed for this version. Install app 01 One-tap install The Progressive Web App opens full-screen with its own Blueprint icon on supported iPhone, Android, Windows, and macOS browsers.
02 Read-only BLE Compatible ELM-style BLE UART devices can be connection-tested before Blueprint requests standardized Mode 01, Mode 02, and limited raw Mode $06 data.
03 Offline session shell The app shell and saved review sessions remain available on the device; VIN, recall, live AI, and cloud sharing still need internet access.
04 Native-app foundation The workflow, privacy model, icons, install metadata, and adapter compatibility lab form the foundation for future Apple and Google store packages.
HOW IT WORKS
From symptom to measured proof Install Blueprint Diagnostics from this page and allow the home-screen icon to be added. Open Diagnostics, decode the VIN, enter the exact code, and open Guided Live Test Mode. Choose a compatible BLE adapter or import a scan-tool CSV, then record the fault under controlled conditions. Use voice-assisted bookmarks, readiness comparison, and an expiring sanitized report link to document the result. Important: This installable version is not an Apple App Store or Google Play listing. Store submission still requires developer accounts owned by Blueprint Diagnostics, native packaging, store review, and platform-specific Bluetooth permissions. Classic Bluetooth serial and background BLE require a native companion rather than ordinary Web Bluetooth.
