AcurastChecker tells you instantly whether a phone is compatible with Acurast Processor — no manual spec-hunting, no searching forums, no guesswork.

=== WHY THIS APP? ===

Finding a compatible phone for Acurast Processor usually means digging through spec sheets, OS version lists, and community spreadsheets. AcurastChecker eliminates all of that. Just snap a photo of the phone's "About Phone" screen and our AI identifies the model and OS version automatically. Then we cross-reference against the official Acurast supported-device list to give you a clear, immediate compatibility verdict.

=== HOW IT WORKS ===

1. Open the app and tap "AI Vision Scan"
2. Point your camera at the target phone's Settings → About Phone screen
3. Gemini Vision AI (secured through Firebase Cloud Functions) reads the model name, brand, and OS version from the image
4. AcurastChecker matches the detected phone against the official Acurast device database — fetched live from Acurast's Google Sheet
5. You receive a clear verdict: High compatibility, Medium, Low, or Unsupported — with a detailed explanation

=== CORE FEATURES ===

• AI Vision Scan — Uses your device camera and Google's Gemini Vision model to identify any phone model automatically. No typing, no searching. Works for both Android and iPhone targets.

• Live Device List — Fetches the latest supported phones directly from Acurast's official Google Sheet on every scan. Includes an AsyncStorage cache (24-hour TTL) so it works offline too, plus a curated static fallback list shipped with the app.

• Instant Compatibility Verdict — Checks OS version against minimum requirements (Android 12+ with locked bootloader and non-rooted, or iPhone 6S+ on iOS 15+). Also verifies whether the device appears in Acurast's Recommended, Tested, or Eligible lists.

• Local Device Detection — Your own phone's model and OS are detected automatically on the Home screen using react-native-device-info. No camera needed for a quick self-check.

• Scan History — Every scan is saved locally with a timestamp. Browse past results to compare phones or revisit earlier verdicts.

• Privacy-First Architecture — Camera images are processed through Firebase Cloud Functions secured by Firebase Authentication (anonymous sign-in) and Firebase App Check. No images are stored. Your data stays yours.

=== WHO SHOULD USE THIS? ===

• Anyone buying a second-hand phone specifically to run Acurast Processor — verify compatibility before you buy
• Existing Acurast users who want to confirm their current device meets requirements
• Sellers listing phones for Acurast use — add a compatibility screenshot to your listing
• Anyone curious whether a random phone they own can be used with Acurast

Instead of cross-referencing specs manually across multiple tabs, just snap a photo and get your answer in seconds.

=== WHAT IS CHECKED ===

• Operating system: Android 12+ (non-rooted, locked bootloader required) or iOS 15+ (iPhone 6S or newer)
• Device status in Acurast's official database: Recommended (fully tested and approved), Tested (confirmed working), or Eligible (meets minimum requirements)
• Hardware capabilities reported by the AI vision model

Note: AcurastChecker is a compatibility verification tool. It does not run Acurast Processor itself. You will still need to install the official Acurast Processor app to participate in the network.

=== PERMISSIONS ===

Camera: Required only for the AI Vision Scan feature, to photograph the target phone's settings screen. No photos are stored or uploaded beyond the immediate scan processing.

=== SUPPORTED DEVICES ===

AcurastChecker itself runs on any Android device running Android 7.0+ with a camera. The phones you check can be either Android or iOS — the AI vision model identifies both platforms.
