Bloom. vs Fractal Architect
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Bloom.
This app generates unique computational art where each pixel has a distinct color. Users can customize algorithms to influence the patterns and apply them as textures to various 3D shapes. It includes in-house music and options to save and reload custom creations.
- Self-generating, pseudo-random color patterns
- Pixel-level unique RGB color generation
- Apply images as textures on 3D shapes
- In-house music for generative art sessions
- Save and reload custom Bloom Documents
- Variety of 3D shape geometries

Bloom is an app that generates computational art, which means images are created by algorithms rather than by hand, but users can customize parameters to influence the results. In Bloom, textures can be generated so that every pixel has a unique color. Bloom is available for macOS and iOS, in a virtually identical experience. To give every pixel in an N×N grid its own unique RGB color, we need enough color variations. With M shades per color channel (red, green, blue), we get M³ total colors. So we choose M so that M³ matches the number of pixels, N²: N² = M³ This algorithm produces endlessly varied patterns that can be applied to a variety of 3D shapes. Feature overview: • Self-generating, pseudo-random process creates unique patterns of a rainbow of colors. • 1000x1000 dimension color profusions consisting of one million different colored pixels, with option of more or less. • Apply generated images, or any other image, as textures on 3D shapes - sphere, cube, heart and more. • Listen to our own in-house music as you watch and wait. Many 3D output options, including texture filters, shape rotation, material and lighting properties. A presets menu provides you with several sets of parameter values that you can start with and then tweak further. Use the Defaults menu item to reset all parameters to the state of Bloom on first launch. Options can be saved to and reloaded from Bloom Documents, using the Share menu. Bloom Documents are created using the Share menu item Save Bloom Sphere Document, and reloaded using the Share menu item Load Bloom Document. Bloom Documents support Quick Look Thumbnails. Quick Look thumbnails are small preview images that the operating system generates for files so you can see what’s inside without opening them. For example, when you browse your files in Finder, each Bloom Document or image may have a tiny preview showing the content or a miniature version of the 3D shape and texture. This makes it easier to identify files at a glance and quickly find what you’re looking for. Available shape geometries: sphere, torus, cube, cylinder, plane, capsule, pyramid, star, trefoil knot, exclamation heart and heart. A Music Manager enables listening to an assortment of music tracks while you wait and watch the art generate.

Fractal Architect is a very powerful flame fractal creation and design app for iPhones and iPads. It makes 2D and 3D fractal images of great beauty. A huge variety of beautiful and unique fractals can be created with tools that are both simple and advanced. Flame fractal images can be awesome images of exquisite beauty. The eye is drawn to symmetry and color patterns, which fractal images possess in abundance. ULTRA FAST RENDERING Metal GPU Accelerated. 10 to 20x faster rendering than on the device's CPU, an option which is also included. We have over 10 years of experience making fractal apps supporting GPU rendering. BUILT FROM THE GROUND UP FOR MOBILE TOUCH Fractal Architect works great with touch and supports iPad features like Multitasking, Multiple app windows, Split View, & Slide Over and Drag & Drop. It has a GUI that works well on both iPad and the smaller iPhone. THE FRACTAL ARCHITECT FAMILY Fractal Architect is available on iOS, iPadOS and MacOS. It has been on the Mac for many years and is now available there as Fractal Architect 5 and Fractal Architect X. But the iOS and iPadOS app is not a *lite* app. It has the same rendering engine as its counterpart on MacOS and the files and the Lua scripts are 100% compatible between the different platforms. SHARING BETWEEN PLATFORMS It supports the Apple Files app, with image thumbnails and Quicklook previews, and you can easily share files with your Mac or iOS devices through iCloud. TOOLS The app has 2 random fractal creation tools. Configured fractals, where you can make your own mixes of 374 different variations (the stuff that builds fractals) both for 2D and 3D flame fractals. The other random tool is Scripted fractals, where you can choose from 46 factory scripts or write your own, by simply saving a good Configured variation mix as a new script. LUA SCRIPTS The script language in FA is Lua. It is used both as Random Fractal Scripts and as Tweak Scripts. Tweak Scripts let you easily make variants of an existing fractal by adding variations and doing different tasks in the app. With Tweak Scripts you can mangle a fractal totally beyond recognition. A basic script editor is included in the app. Compatible with iOS text editing apps like Textastic and GoCoEdit. TRANSFORM EDITOR In the Transform Editor, you can change the very building blocks of the fractal or build your fractal from scratch. If you have used a flame fractal app before you will recognise the system with transforms that contain variations and are controlled by manipulating a triangle for 2D fractals. FA also lets you do the same with 3D fractals but with a 3D Tetrahedron instead of a flat triangle, editing fractals in real 3D space. FA also uses a unique system of serial and parallel groups of variations. THE VARIANTS EDITOR Here you can make very controlled random variants of a fractal by randomizing colors, symmetry, transform and variation weights, parameters, matrix, xaos and more. In this editor, you can take a good fractal and make a multitude of new great fractals from it. There is also a Target function that lets you decide exactly what part of a fractal to randomize. All fractals you like can be saved in the Favourites, to build collections or making sure you don’t lose all the good ones you find. You can add fractals to Favourites from all parts of the app. LAYERS You can easily layer fractals. Simply select the fractals you want to layer and use a menu command to layer them. Layered fractals can also be randomized in the Variants Editor and edited in the Transform Editor. WHAT IT DOES NOT SUPPORT Fractal Architect for iOS and iPadOS supports most of the features of the Mac version but not all. There is no animation and it lacks the advanced Animation Sequencer found on Mac. Notice: GPU rendering may not work with all fractals. Render performance depends on the power of the iOS device's CPU & GPU.

Verdict
The clearest difference is price: Bloom. at Free against Fractal Architect's $9.99. Bloom. also leads on rating (5.0 vs 4.1). Fractal Architect's advantage is update cadence (every 6 weeks vs every 4 months) and chart position (#147 vs unranked). On ads, in-app purchases and device support there is nothing between them.
