Not just the answer — a real explanation, the way a tutor would give it. Stuck on a problem? Take a photo. Your tutor writes out the full solution step by step on a blackboard, explaining the reasoning behind each step out loud — like having a teacher sitting beside you, writing and talking you through it. Made for middle school and high school students.
