Leaper - Workbook For STEM

New Semester is Comming! Download Leaper to save your grade!

Leaper is a practice app for undergraduate mathematics and practical programming/designing tool skills.

There are many lectures, but not enough problem books for the subjects people actually struggle with. Leaper was built to fill that gap. Practice college STEM subjects such as Calculus, Linear Algebra, Differential Equations, Real Analysis, and Statistics, along with practical tools such as Excel, Linux, Git, Python, C#, Go, Rust, AutoCAD, SolidWorks, Blender, Rhino, Grasshopper, and Structural Mechanics.

Leaper is not just about memorizing answers.
Each question is designed to help you recall concepts, recognize patterns, diagnose situations, and choose the right next step.

Key features:

• Practice routines for college STEM subjects
• Practical drills for Excel, Linux, Git, and developer tools
• CAD, 3D, and engineering tool questions
• Short daily sessions for consistent learning
• Wrong-answer review and concept recap flow
• Question reporting for quality improvement
• Personalized subject visibility settings
• English and Korean question banks

Leaper does not replace lectures, books, or real projects.
It gives learners a repeatable practice environment so they can turn concepts into judgment.

Free users can try beginner practice for a selected subject.
Paid plans unlock broader subject access and expanded question banks.

Leaper is built for college students, developers, practitioners, architecture and engineering learners, and anyone who wants stronger fundamentals in the age of AI.

Lectures are everywhere.
The problem book is missing.
Leaper brings it back.
