a-Shell mini is a complete local terminal emulator, allowing to run most Unix commands on you iOS device. You can transfer files using scp and curl, edit them with vim and ed, process them using grep, awk and sed. Work with git repositories using lg2. Most commands are compiled for iOS native Arm64 format, making them fast and well integrated with iOS underlying BSD Unix. a-Shell mini includes Python, Lua, JavaScript and webAssembly for programming and scripting. It also includes native ffmpeg and convert for fast image and video conversion. 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 mini 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 mini uses iPadOS 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. a-Shell mini is a minimalist terminal, designed to have a very small footprint (less than 250 MB). If you need more commands, please consider a-Shell, which has more Python packages, more JavaScript modules, Perl, make, a C and C++ compiler and TeX.

RuntimeBrief turns activity from your local coding agents and repositories into short, evidence-backed project updates. Connect the app to the RuntimeBrief daemon running on your Mac to see what changed, what is still in progress, and what needs your attention. Each claim links back to its supporting commit, working-tree scan, or agent session. Features: • A concise portfolio brief across your registered projects • Evidence-backed project status and recent agent activity • Native Claude Code tasks in registered projects, with model and permission choices and takeover in Claude Desktop on your Mac • Optional, on-demand analyst answers through your own Codex CLI login • Local Xcode, TestFlight, and App Store release summaries • Siri and Shortcuts access to project status • Saved briefs when your Mac is temporarily unavailable • A fully offline fictional demo requiring no account or server RuntimeBrief has no hosted account, analytics SDK, advertising SDK, or public cloud relay. Live project data stays under your control on your Mac and private network. Optional analyst processing follows the data controls of the ChatGPT workspace selected in Codex CLI. Native Claude tasks use your existing Claude login and follow Claude's account policies and the selected tool permissions. A Mac running runtimebriefd is required for live project data. The in-app demo can be explored without installing or configuring anything. Native tasks also require Claude Code and Claude Desktop installed and signed in on that Mac.
