Letter Scanner – Smart Mail Sorting Made Simple
Transform Your Mail Sorting Process
Letter Scanner is a powerful yet easy-to-use mobile application designed to revolutionize how you sort and categorize mail. Built specifically for mail sorting facilities, delivery services, and postal workers, this app uses cutting-edge optical character recognition (OCR) technology to instantly identify street addresses and categorize letters into organized groups.
Why Letter Scanner?
Every day, thousands of letters need to be sorted quickly and accurately. Traditional manual sorting is time-consuming, prone to errors, and physically demanding. Letter Scanner changes the game by combining the power of artificial intelligence with the convenience of your smartphone camera.
Simply point your phone at a letter’s address, and within seconds, the app recognizes the street name, assigns it to the correct delivery group, and even announces the category audibly. No buttons to press, no complicated steps—just hover, scan, and sort.
Key Features
🎥 Real-Time Live Scanning
Experience lightning-fast mail sorting with our real-time camera scanning mode. Just hold your phone over the letter’s address, and the app instantly detects and categorizes it. No need to take photos—the app processes everything in real-time, making your workflow seamless and efficient.
🔊 Audio Announcements
Keep your eyes on the work, not the screen. Letter Scanner announces each detection audibly, telling you which group (A, B, C, or D) the letter belongs to. This hands-free feature helps you maintain your sorting rhythm without interruption.
⚡ Lightning-Fast Performance
Sort up to 20-30 letters per minute with automatic 1-second result display and instant camera reset. The app is optimized for speed, helping you process thousands of letters in a fraction of the time traditional methods require.
📊 Real-Time Statistics
Track your productivity with live counters that show total letters scanned and breakdown by category. Monitor your progress throughout the day and identify peak performance times.
🗂 Unlimited Street Database
Add as many streets as you need—hundreds, thousands, or more. The app’s powerful database can handle extensive street lists without slowing down, making it perfect for large sorting facilities covering multiple regions.
✏ Easy Street Management
Add, edit, or remove streets from your database anytime. The intuitive management interface lets you quickly update your street list as delivery routes change or expand.
🔦 Built-in Flash Support
Work in any lighting condition with integrated flash control. Perfect for early morning shifts or dimly lit sorting facilities.
🎯 Smart Detection Technology
Our advanced OCR engine recognizes both printed and handwritten addresses with impressive accuracy. The app uses fuzzy matching algorithms to catch variations in street names and spellings, ensuring reliable detection even with imperfect handwriting.
📱 Works Offline
Once your street database is set up, the app works completely offline. No internet connection required during scanning, making it reliable in any work environment.
🎨 Beautiful, Intuitive Interface
Modern design with clear color-coded groups makes it easy to distinguish between categories at a glance. The large, bold displays ensure you never miss a detection, even in fast-paced environments.
How It Works
1. Setup Your Database
Start by adding all the streets in your delivery area to the app. Assign each street to a group (A, B, C, or D) based on your routing system. This one-time setup takes just minutes.
2. Start Scanning
Open the Live Scan mode and point your camera at the letter’s address. The app automatically detects the street name and displays the assigned group with a color-coded visual and audio announcement.
3. Sort and Track
Place the letter in the corresponding group bin. The app keeps count of how many letters you’ve sorted and breaks it down by category, helping you stay organized and productive.
4. Repeat
The app automatically resets after each detection, immediately ready for the next letter. No tapping, no waiting—just continuous scanning.
