Our Products
Our latest initiative in the educational space is the MathOtter™ web application. MathOtter is a source of free unlimited GED math practice problems, answers and help. Step-by-step solutions are available for each problem, making it an ideal tool for students preparing for the GED math test or anyone looking to improve their math skills.
This is an installable web app. No download needed. Just open MathOtter in your browser, tap 'Add to Home Screen,' and it launches like any other app on your device. (Android devices will prompt whether you want to install the app.)

It took a couple hundred hours to develop this app - even with agentic AI. (It's about 30k lines of code.) The problems, step-by-step solutions and information screens are carefully crafted to present algebra and illustrations correctly (using techniques such as KaTeX and SVG) and to incorporate effective pedagogical techniques. The app code generates problems designed to yield clean integer answers wherever applicable. This allows students to focus on learning problem-solving techniques without being distracted by unnecessary decimal values (which, for some students, can look confusing).
All math problem generation and logic is handled client-side—no user authentication or server-side rendering is used. The only backend interaction is a single anonymous POST to an API gateway endpoint for usage tracking.
