Mandel Draw is an application that allows you to enjoy fractals, Mandelbrot sets and filled Julia sets, in a fast and comfortable way. The app allows you to draw an infinite number of fractal images from up to 80 different functions, 20+α color palettes, and freely configurable Julia parameters. Operation is simple. Drag to move, pinch to zoom in and out. Double- and triple-tap operations are also available. Convenient settings are also available. - Use DF64 operation: Double the float operation to make it possible to zoom in more. (Disabled in the Appendix 1,2) - Select render version: Two types of rendering methods can be selected. - Display coordinates and magnification: The current coordinates and magnification will be displayed on the screen. - Output detailed information: Add detailed information to the text when sharing. - High-resolution output: Outputs at 4 times the vertical and horizontal resolution when sharing. - iCloud Sync: Share favorites and My Palette with another iPhone or iPad. In addition, all functions are available when unlocked with in-app purchase. 1) All functions are selectable 2) All palettes can be selected 3) Up to 2000 favorites can be saved 4) Maximum number of My Palettes that can be saved is now 30. Now, please enjoy the wonderful and mysterious world of fractals. What is a fractal? Simply put, a fractal is a self-similar figure that does not lose its complexity no matter how much it is enlarged. (Though computers have their limitations.) There are various fractal shapes, such as the Koch curve, Sierpinski's gasket, and Menger's sponge. The Mandelbrot set and the filled Julia set are fractals drawn computationally on the complex plane.

SubsetJuliaVM is an offline runtime for running Subset Julia programs on iOS and iPadOS. • Run code locally on-device (no code is downloaded from the network) • Built-in samples to learn and experiment quickly • Designed for education, demos, and lightweight scripting Notes SubsetJuliaVM is an experimental virtual machine that executes a carefully designed subset of the Julia language on iPhone and iPads. This app is intended for developers, researchers, and advanced users who are interested in programming language design, virtual machines, and cross-platform execution. Key features Execute a subset of Julia in a lightweight VM environment Designed for experimentation, education, and research Built with a focus on clarity and extensibility rather than mass-market polish Important notes This is not a full Julia implementation Performance and compatibility may vary depending on the device The app is actively developed and may change over time Why is this app paid? SubsetJuliaVM is a specialized tool, not an advertisement-driven product. Your purchase directly supports continued development, maintenance, and future improvements. If you are curious about how programming languages work under the hood, this app is for you.

Verdict
The clearest difference is price: Mandel Draw at Free against SubsetJuliaVM's $7.99. Mandel Draw also leads on iOS requirement (16.0 vs 18.6). SubsetJuliaVM's advantage is in-app purchases (none vs 1) and update cadence (daily vs weekly). On ads and device support there is nothing between them.
