Amazing new mathematical programming tool. Now in offer: 50% off. Eureka is a mathematical programming environment that is able to transfer the characteristics of the most sophisticated programming languages to your personal mobile device (iPhone, iPad) Eureka will prove to be invaluable to your work because of its: • Computing power. It comes with basic and advanced mathematical functions from the most sophisticated libraries. • Flexibility. It can be customised and fully adapted to meet your technical and scientific needs as it can be configured to show the functions that you need for your job and hides those that you do not. • Naturalness. Eureka uses a symbolic language designed and developed in-house called Magic that enables formulae to be written naturally, that is, it uses generally accepted mathematical notation and symbols, which makes formulations extraordinarily natural, easy to use and read. • Ease of use. Its natural language, symbolic representations, meticulously designed keyboard – divided into readily accessible and intuitive panels, its customisable settings and flexibility mean that the system is easy to use and quick to program, all of which makes it a simple and efficient tool.

Verdict
The clearest difference is update cadence: Physics Formulas at every 2 months against Eureka Calculator's every 17 months. Eureka Calculator's advantage is iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
