## Description

Transform tedious test grading into a fast and modern process with the ultimate tool for educators. Built from the ground up with the latest Android technology, this app not only generates accurate rating scales, but now reads them for you. Star Feature: Smart OCR with OpenCV. Forget manual input. Our new Optical Character Recognition (OCR) feature lets you: • Instantly Scan Scores: Point your phone's camera at a score and get the corresponding grade instantly, according to your active scale. • Improved Accuracy: We've integrated image pre-processing with OpenCV to clean and optimize the image before recognition, maximizing accuracy even with difficult handwriting. • Dual Capture Mode: Choose between manual mode for spot captures or activate automatic mode for continuous, effortless grading. Professional and Secure Scale Management • Precise Calculation: Faithful to the Chilean evaluation system, using a two-part conditional formula that guarantees fairness and accuracy. • Robust Storage with DataStore: Your scales are stored securely and asynchronously using Jetpack DataStore technology. Your data is safe, works perfectly offline, and is immune to production build errors that affect other apps. • Complete Management: Easily create, modify, rename, delete, and share your scales. Superior Technical Quality: This app has been refactored to follow industry best practices: • 100% native and fluid interface built with Jetpack Compose. • Modern and reactive architecture with StateFlow for optimal performance. • Optimized performance for the latest devices, including support for 16KB memory page sizes. Download now and spend less time calculating and more time teaching.
