Adaptive difficulty
Difficulty adjusts as you answer.
Your education level and a placement test help establish where to begin. Each subject is measured independently.
An estimator updates your difficulty from your answers in each subject. The scale runs from Beginner to Research. Your level in one subject does not set your level in another.
Start with a challenge near your current level.
Your level adjusts over time, based on your answers.
Explain Anything
Break down a concept, follow the steps, or ask for another explanation.
Saved conversations let you pick up where you left off and keep asking follow-up questions.
Opportunity cost is the value of your next-best option. A choice can have a cost even when no money changes hands.
One concept. Three ways to understand it.
Personal coach
Your coach uses your goals and recent answers to recommend focused practice.
Your recent answers show where you need practice. Your goal helps your coach choose a focus.

Time counts only while you’re solving.
Progress in one subject never changes your level in another.
Evidence before percentages. Early on, see “7 of 9 right.” Rates appear from 10 attempts and always include their sample size.
Progress, without the guesswork. “Improving” requires a statistically clear change. Otherwise, the app says “steady” or “too early to tell.” Levels move through solving, not time spent. Moozgy does not invent a reason for a missed answer.
Moozgy is a mental-fitness app for iPhone and iPad: a vertical feed of hard problems for people 13 and over who want a real mental challenge every day. Each card is a question in one of seven subjects (Math, Geography, History, Economics, Philosophy, Computer Science and SAT® prep), with difficulty from Beginner to Research. In adaptive mode, Moozgy uses your answers to adjust the difficulty of the feed. Explain uses AI to answer your questions step by step, and with a Full Brain subscription, Coach builds a daily plan from your own answers.
