At the moment there is only one version for macOS publicly available.<\/p>\n
The most recent\u00a0release of the Girih App<\/b> is available at:<\/p>\n
\u00a0 The most recent\u00a0release of the Zellige App<\/b> is available at:<\/p>\n \u00a0 The most recent\u00a0release of the Hedron App<\/b> is available at:<\/p>\n \u00a0 The Zellige App and Girih App is as easy to use as putting tiles of a jigsaw puzzle together. Look at the menu File -> Examples<\/strong>.<\/p>\n Look at the Help<\/strong> menu.<\/p>\n Create your own design by starting with a decagon. Then surround it with pentagons. I have made YouTube playlists for the Girih App<\/a>, the Zellige App<\/a> and the Hedron App<\/a>.<\/p>\n The Girih App does not limit the image size.<\/p>\n The size will only be limited by your hardware and operating system.<\/p>\n If you double click the scale factor field in the export dialog, the scale factor is recalculated to match a maximum width or height of 13500px. But you can also enter bigger sizes.<\/p>\n 13500px is very well tested, which is up to 182 Megapixels, which should be good enough for most use cases. Let me know, what your preferred size is.<\/p>\n Writing the Girih App took more than three\u00a0years. Features of macOS which would not be ported to Windows:<\/strong> Features which are built-in macOS which have to be re-implemented manually with lots of effort for windows:<\/strong> The whole user interface has to be completely rewritten.<\/p>\n Many of the code of the macOS App can be reused for iOS. Files can be shared between the macOS Girih App and the iOS App via iCloud Drive. Icons in the iOS App and the File App show a preview of the file. Export to SVG is already working.<\/p>\n The iOS App so far can read and display files. Zoom, rotate and pan is possible in this early stages. Shapes can be selected, copied and added.<\/p>\n Selected shapes can be deleted.<\/p>\n Three rhombs in a hexagon can be swapped via drag and drop.<\/p>\n The shape selection panel is implemented. The iOS version is intended to support as well iPad and iPhone devices.<\/p>\n Rubberband to select multiple shapes in the main window has to be implemented. In this state the app is already usable and useful on iPad and iPhone to create new designs on the the device.<\/p>\n The example menu is missing. macOS does support 80-Bit floating point operations, which iOS does not. An Android version should be done after all the user interaction changes are solved for an iOS version. Yes. I started developing my Apps on a Mac Book Pro from 2010 and it still works there.

\nVersion 3.4 from\u00a0September 2026.<\/strong><\/p>\n<\/a>
\nVersion 3.3 from\u00a0September 2026.<\/strong><\/p>\n<\/a>
\nVersion 2.4 from\u00a0July 2026.<\/strong><\/p>\n
\nHow easy it it to use the App?<\/h2>\n
\nBut in contrast to a jigsaw puzzle, where you can only build one fixed design, with the Zellige App and Girih App you can build any combination of the tiles and with any colors you want.<\/p>\n
\nHow do I start using the Girih App?<\/h2>\n
\nDouble click<\/strong> your already placed decagon. Now you can add more decagons.
\nLook at the toolbar<\/strong> for matching shapes to fill the gaps.
\nIf you want to remove shapes from your design, use drag and drop<\/strong>.<\/p>\n
\nWhat is maximum image size that can be exported\u00a0as PNG or JPG?<\/h2>\n
\nWill there be a Windows Version?<\/h2>\n
\nWriting a Windows Version of the Girih App would also take a lot of valuable time.
\nThis time could better be spend into another macOS App which never seen before features.
\nNot all features of the macOS App would be available under windows.
\nOther \u201efree\u201c macOS features have to be reimplemented for Windows.
\nI do not know how useful Swift programming for Windows is at the moment. Otherwise everything has to be completely rewritten.
\nI do not have a development Windows PC.<\/p>\n

\nWill there be an iOS Version?<\/h2>\n
\nBut the user interaction has to be different. There are no mouse-events without clicking on a touch device.
\niPads are much slower than a Mac. Some extra time for\u00a0further performance optimizations has\u00a0been done.
\nA\u00a0rudimentary iOS version has been started. So far it supports file handling including iCloud support.<\/p>\n
\nThe file format is exactly the same. The code for reading and writing is exactly the same.
\nI found no documentation how to add tags to a file on iOS. iOS users can view and modify tags manually.
\nSo tags saved by the macOS Girih app will be visible on iOS, but the iOS app does not update these tags.<\/p>\n
\nSave and Autosave works. iOS does not support writing of tags.<\/p>\n
\nSelection of multiple shapes will not be supported on iOS.
\nThe macOS version uses the Shift-key and rubber bands for selecting multiple shapes.
\nCategories have been added to the shapes panel. But they have currently no menus which would made access to subcategories faster.
\nThe detail view has to be added to the shapes panel<\/p>\n
\nThe iOS 14 color picker is used.
\nAt least the first release will not support pattern on the tiles to improve performance and save implementation time.<\/p>\n
\nThe help window is missing.
\nNo parameters like border with can be changed inside the app.<\/p>\n
\nOn iOS 64-Bit floating point operations will be used instead.<\/p>\n
\nWill there be an Android Version?<\/h2>\n
\nI do not know how useful Swift programming for Android is at the moment. Otherwise everything has to be completely rewritten.<\/p>\n
\nCan I use the files, which I create with the app, for commercial purposes?<\/h2>\n
\nYou can use your designs for commercial purposes.<\/p>\n
\nWill the App also run on older Computers?<\/h2>\n
\nMeanwhile I am using a recent Mac Book Pro.
\nThe old Mac has only OpenGL and not the better Metal rendering.
\nSo it has no physical based light rendering and changing the metalness and roughness of the surface has no effect on the old computer.
\nThis affects only the 3D visualization of the Zellige App and Girih App.<\/p>\n
\nOnce purchased can the app be transferred to another computer, when I buy a new one?<\/h2>\n
\nSince the license of the App will be purchased via the Mac App Store, you can use it on all your computers, which are connected to your Apple ID. And since I allow family-sharing<\/a> in my Apps, your family members can use it on their computers too without additional costs.<\/p>\n
\nCan I get a volume discount?<\/h2>\n
