About this app

Beyond just scanning—Assemble and Restore.

SeqScan is a professional-grade sequential QR scanner designed to collect fragmented data across multiple QR codes and restore them into their original, complete text.

While standard scanners only handle single-action codes, SeqScan is built for "Data Sequences." Whether it’s large text split into multiple parts or animated QR codes used in secure environments, SeqScan ensures not a single piece of information is lost.

### KEY FEATURES

1. Sequential Data Assembly
Automatically detects the order and total count of fragmented QR codes. It intelligently organizes parts based on indices (e.g., JSON, 1/10, or key=value formats) to reconstruct the original message perfectly.

2. Real-time Diagnostic Dashboard
Don't guess if you've missed a part. SeqScan provides live feedback on:

Total parts collected vs. expected.

Specific missing indices (e.g., "Missing part #4").

Duplicate detection and conflict resolution.

3. Rescue Scanner (Android Optimized)
Stuck on a hard-to-read code? Use the dedicated 'Rescue Mode' to focus on missing segments with higher precision, ensuring 100% data recovery even in challenging conditions.

4. Smart Anti-Misrecognition
Built-in verification logic prevents accidental scans or data corruption. It re-validates conflicting parts to maintain the highest data integrity.

5. Session Persistence & Auto-Save
Never lose your progress. If you close the app mid-scan, SeqScan remembers exactly where you left off, allowing you to resume long data sequences anytime.

6. Global Language Support
Fully localized in 10+ languages including English, Spanish, Korean, Portuguese, Japanese, French, German, Chinese, and Hindi.

### HOW IT WORKS

Start the scanner and aim at the first QR code.

Continue scanning the sequence; the app tracks the progress and duplicates automatically.

Once all parts are collected, view the fully restored text.

Instantly share or save the result to your favorite apps like Google Keep, Email, or Messaging tools via the system share sheet.

### PREMIUM MODEL
