Mandel Draw vs Moonbound

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.

Moonbound turns your phone into a guide for observing the Moon through a telescope: point and it tells you what you're looking at, live. Mount your phone to your telescope's eyepiece with a simple adapter, and Moonbound uses your camera to recognize lunar seas (maria) in real time, right on the live image; no guesswork, no atlas to cross-reference by hand. EVERY NIGHT, A REASON TO LOOK UP Moonbound computes tonight's real moon phase, illumination, and moonrise/culmination/moonset from actual astronomical data, then recommends which lunar features are worth finding tonight, based on what's genuinely visible. GUIDED, ONE DISCOVERY AT A TIME During an observation session, Moonbound walks you through your targets one at a time, never a cluttered screen of overlays. Tap a detected feature for a short, plain-language description. YOUR OBSERVATIONS, REMEMBERED Every feature you find is logged automatically to your personal Observation Journal, grouped by night, no manual note-taking. Revisit any discovery later for a fuller page: diameter, age, and interesting facts. BUILT FOR BEGINNERS, GROUNDED IN REAL ASTRONOMY No accounts, no subscriptions, no configuration. Moonbound works offline (location is optional, only used to show moonrise/set times) and recognizes 10 lunar maria, from Mare Crisium in the east to Oceanus Procellarum in the west, each trained to be identified directly, so even a single visible sea is enough for a confident match. WHAT YOU NEED - An iPhone - A telescope with a simple eyepiece-to-phone adapter - A clear night Whether it's your first time finding Mare Tranquillitatis or your fiftieth night under the stars, Moonbound is a quiet companion for actually understanding what you're seeing.
