Design RC, RL, and RLC filters (2nd–7th order) with Butterworth & Chebyshev alignments, passive crossovers, RLC band-pass/reject, and Twin-T notch—enter specs to instantly get component values and quick Bode insights in a clean, offline-friendly, dark-mode UI for lab, classroom, and audio/embedded work. What you can design: -RC & RL filters: low-pass / high-pass, 2nd–7th order -RLC filters: band-pass & band-reject (notch) -Butterworth: maximally flat magnitude -Chebyshev: ripple-tuned sharpness -Twin-T notch: precise mains or tone suppression -Passive crossovers: 2-way/3-way starter calculations Built for engineers, hobbyist and students, it turns specs into trustworthy parts fast—so you can prototype smarter, learn by tweaking, and move from idea to BOM with confidence.
Simplex Linear Programming

Master the mechanics of Linear Programming with an industrial-grade, visual Simplex solver. Whether you are an undergraduate student tackling Operations Research homework or an engineer optimizing complex systems, this app provides a high-performance, native environment to solve and visualize linear models. Built with Apple’s Accelerate Framework (vDSP), the engine performs hardware-accelerated matrix operations for desktop-class speed on your mobile device. Why this is the ultimate optimization tool: Visualize the Feasible Region: See your constraints come to life on an interactive Canvas. Plot the quadrant, identify intersection points, and explore the feasible region with intuitive gestures. The Simplex Journey: Watch the algorithm navigate from the origin to the optimal solution. Our "Visual Walker" tracks every iteration, highlighting each vertex transition with a clear, orange path. Professional Grade Logic: Full support for Big-M and Two-Phase methods. Easily handle ≤, ≥, and = constraints without needing to manually convert your model. Precision Entry: Clean, monospaced interface featuring color-coded inputs for coefficients, objective goals, and variable signs. Education-First Design: Perfect for learning the geometry behind the algebra. Follow the path, analyze the coordinate labels, and see exactly where the "Optimal" solution sits in the coordinate plane. Purely Native: No web wrappers or lag. Experience a fluid SwiftUI interface designed for "Engineering Soul"—performance, clarity, and reliability. Student & Professional Value Proposition For Students: Use it as a powerful "Check Your Work" tool. Compare your manual pivot steps against the visual path and verify your feasible region boundaries. For Professionals: Quickly prototype constraints and objectives on the go with a solver that respects hardware limitations and mathematical rigor.
