## What is opero?

Opero: Math Quest is a math practice app designed for kids.

Children improve their math skills through configurable tests, friendly duels, and smart feedback that explains what to improve and how.

Kids can answer math questions in three different ways:
• Voice input
• Drawing answers on screen
• Typing using the keyboard

Features:
• Practice addition, subtraction, multiplication, and division
• Configurable math tests for daily practice
• Duels between two players to stay motivated
• Personalized feedback from a virtual coach
• Multiple input methods: voice, drawing, and text
• Kid-friendly design with no accounts or sign-ups

Opero works completely offline. All data stays on the device, and no personal information is collected.
