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.

Modbus Poll is a mobile Modbus TCP master and diagnostic tool for engineers, technicians, and integrators who need to check on PLCs, sensors, and industrial devices without carrying a laptop. CONNECT & POLL • Modbus TCP client — connect to any device on your network by IP and port • Read Coils, Discrete Inputs, Holding Registers, and Input Registers (FC01–FC04) • Write single or multiple coils and registers (FC05, FC06, FC15, FC16) • Configurable slave ID, start address, quantity, and poll interval • Live TX/RX/error counters so you can see connection health at a glance MAKE SENSE OF THE DATA • 24 display formats: signed/unsigned, hex, binary, 32-bit long, float, and 64-bit integer/double — in all four standard byte orders • Per-register aliases so "400012" becomes "Tank Level" • Custom scaling formulas (e.g. x/10) to convert raw register values into real-world units • Live sparkline charts per register, with min/max and history FIND DEVICES FASTER • Network scan across a subnet to discover responding Modbus TCP devices • LAN port scan for general network diagnostics LOG & SHARE • Log live polling data straight to CSV • Share the log file instantly via the system share sheet — AirDrop, email, cloud storage, wherever you need it BUILT FOR THE FIELD • Clean, fast interface with light and dark themes • Works over Wi-Fi or cellular — anywhere your device reaches the target network Whether you're commissioning a new panel, chasing down a communication fault, or just need to peek at a register value between meetings, Modbus Poll puts a full Modbus master in your pocket.
