Glass - DECA

Glass is an offline study app for DECA competitors. There's no account to create, and nothing about how the app is used gets tracked. It runs fully with the phone in Airplane Mode. PRACTICE THAT EXPLAINS ITSELF 600 practice questions cover all six DECA clusters. Every question explains why each of the four answer choices is right or wrong, so a wrong guess still teaches something specific. MOCK EXAMS Full-length practice exams run under a real time limit. Set the question count and the time limit, then review the results by topic afterward. ROLEPLAY PRACTICE 71 roleplay scenarios come with a business brief and a prep timer, scored against the rubric categories a judge uses. Quick Think adds short situational drills with instant feedback. MISTAKES COME BACK A wrong answer goes into the mistake notebook. It returns for review until it's answered correctly twice, so studying targets what actually needs work. TRACK WHAT'S WORKING Accuracy and mastery are broken down by performance indicator, making it clear which topics are ready and which still need time before exam day. WIDGETS Several widgets are available for the Home Screen, along with a daily study fact for the Lock Screen. Each one updates on its own, without opening the app. AI FEEDBACK, WHERE SUPPORTED On devices that support it, AI can write feedback on roleplay responses and answer explanations, generated entirely on the device. AI writes feedback. It never decides the correct answer, which always comes from the question bank. PRIVATE BY DESIGN There's no account and no analytics. Nothing typed or answered leaves the phone. Glass is an independent study aid. It is not affiliated with, endorsed by, or sponsored by DECA Inc. or DECA Ontario. The questions and roleplay scenarios in this app are original material written for study purposes and are not official DECA competition content — always confirm current event details with DECA Ontario.
