Slopes is an interactive environment for exploring graphical solutions to ordinary differential equations. Slopes consists of six activities with preloaded examples to get you started and the ability to input your own content. "Slopefields" and “Phase Planes” both plot vector fields and solutions corresponding to multiple initial conditions. “Systems” dynamically solves systems of up to six equations. “Oscillations” solves second-order constant coefficient equations and animates the corresponding spring-mass system or RLC circuit. “Methods” constructs numerical approximations of a single ordinary differential equation using Euler’s method as well as Second and Fourth Order Runge-Kutta methods. "Bifurcations" creates a bifurcation diagram and shows the stability of equilibrium points. Slopes is a playground for ODEs. You can use it for homework, in-class activities or a new research project.
Memetics

Discover the science of memetics - the revolutionary field that explains how ideas spread like viruses through society, influencing your beliefs without your awareness. Ever wondered why certain trends go viral while others fade? Why some ideologies persist for centuries? The answer lies in memetic theory, a discipline most have never heard of yet governs everything from brand preferences to political beliefs. This app has no ads, no account creation, no data collection, no fluff just straight to the education. Memetics reveals how cultural replicators - memes - compete for space in your mind using sophisticated propagation mechanisms and cognitive hooks. These invisible forces shape your worldview more profoundly than most realize. This comprehensive reference app equips you with: - In-depth exploration of memetic theory foundations established by Richard Dawkins, Daniel Dennett, and Susan Blackmore - Interactive flashcards to master key terminology and concepts - Complete dictionary of memetic terms from "cognitive hooks" to "information cascades" - Analytical frameworks for understanding memetic spread and evolution - Case studies of major ideological memes including capitalism, nationalism, and conspiracy theories - Personal memetic journal to track meme exposure in your daily life - Challenging quizzes to test your understanding - Convenient cheat sheets for quick reference - Curated hot links to vital memetic resources Part of our Modern Thinking series designed for an AI-driven world, Memetics provides essential knowledge for navigating our information landscape. Understanding memetic selection, transmission vectors, and memeplexes isn't just academic - it's your defense against manipulation and pathway to more conscious idea adoption. Equip yourself with memetic literacy. The ideas you encounter aren't random - they're engineered for propagation. Shouldn't you understand the mechanisms governing what you believe?

Verdict
The clearest difference is price: Slopes at Free against Memetics's $0.99. Memetics's advantage is iOS requirement (12.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
