a vs LayoutStudio

a-Shell is a complete local terminal emulator, allowing to run most Unix commands on your iOS device. You can transfer files using scp and curl, edit them with vim and ed, process them using grep, awk and sed. You can work with git repositories using lg2.  Most commands are compiled for iOS native Arm64 format, making them fast and well integrated with the BSD Unix that powers iOS/iPadOS. a-Shell includes Python, Lua, Perl, JavaScript, C, C++ for programming and TeX (texlive 2025, with Tikz and LuaTeX) for text processing. There are also multiple network utilities: nslookup, ping, whois, ifconfig... Type help for help, help -l to get the full list of commands. a-Shell can be controlled from Shortcuts: run commands in order, process files in a-Shell, get the results as text or files, transfer files to other apps... a-shell uses iOS 13+ “multiple windows” ability, so you can run multiple shells at the same time, with different commands, in different directories. You can edit a file in one window with vim and process it in the other with python. Compile your C or C++ programs to webAssembly using clang or clang++, and execute the resulting binary. A complete webAssembly SDK is included (WASI-libc). a-Shell is the complete version. If you need a smaller app, and you don't need a C compiler, a TeX engine, or numpy and matplotlib, there is a-Shell mini.

LayoutStudio is a focused visual workspace for designing and reviewing native asset layouts before implementation. Build visually Add titles, descriptions, advertiser labels, icons, main images, calls to action, ad labels, privacy elements, custom text, and boxes. Move and resize each asset directly on the canvas, then enter exact position and size values when precision matters. Preview in context Switch to a clean preview without editing controls. Try neutral colors, gentle gradients, a local image, or built-in mock templates as the background. Adjust zoom and canvas presentation to check whether the layout feels natural in its intended surroundings. Keep your work moving Save projects locally, reopen saved work from the project list, and recover the latest draft after an interruption. Coordinates and sizes remain part of the portable layout document so the design stays consistent across different displays. Designed for focused work Optional grids, snap-to-grid, undo and redo, image scale options, a clean full-screen preview, and draft recovery help you iterate without unnecessary setup. Image selection uses the system picker, and project content stays in the app's local storage unless you choose to share an exported preview. LayoutStudio is a layout prototyping and review tool. It does not request, bind, validate, or serve native ads inside the editing canvas.
