Rainbet

Rainbet is a simple math training app for practicing everyday arithmetic skills.

Practice addition, subtraction, multiplication, division, or use Mixed mode to solve different types of problems in one session. Questions are generated automatically, so each practice session is different.

Choose one of three difficulty levels:
• Easy - numbers up to 10
• Medium - numbers up to 50
• Hard - numbers up to 100

Two training modes are available. In Normal mode, you can solve problems at your own pace. In Speed mode, you have 30 seconds to answer as many questions as possible.

Correct answers add 10 points to your score, while incorrect answers subtract 5 points. Consecutive correct answers build your streak and help you reach achievement milestones.

At the end of each session, you can review your score, accuracy, best streak, and star rating.

The statistics section tracks:
• Total problems solved
• Accuracy
• Best score
• Best streak
• Progress by operation
• Achievements

Progress is saved automatically on your device.
