A homework-help app from South Korea, popular across Asia. A student snaps a photo of a math (or other) problem and gets a step-by-step solution from a large problem database or an AI chat, can ask follow-up questions, and can make quizzes or practice tests from uploaded school exams. It also has study timers, notes, a student community and, in some countries, paid live tutoring. Most users are middle and high school students.
Our take: Can help an older student check their work and see the steps, but it is an answer engine with ads and tracking; younger kids and families wary of data collection should skip it.

Data and privacy
Collects name, email, gender, birth date, school, grade and exam scores, photos of questions, device IDs, location and an advertising ID. The policy uses data for marketing and personalized content, and the App Store label says location, identifiers and usage data may be used to track users across other companies' apps; nothing on AI training or COPPA was found. Read the privacy policy.
Does it work?
The maker's own claims only: 97 million students served and about 100 problem searches per second. No independent study of learning effects was found.
