Abacus Calculator
Advanced scientific calculator.
Abacus is a passion-project-turned-viable-product. Years ago, I bought a calculator app to help me with my studies because the iOS calculator wasn't enough. In 2023, they transitioned to being a subscription app and got rid of my paid-for features, and stuffed it full of ads.
atgs Abacus seeks to right that wrong. It's already a great scientific calculator, ahead of the iOS by miles, with functions, variable, and graphing. Soon, it will include a companion mode to help you actually LEARN the math, support for common calculus and trig problems, linear algebra support and beyond.
