Features
Read full description

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.

Verdict

The call

The clearest difference is ads: a at none against Expo Go's shown. a also leads on review sentiment (78% vs 56%) and monetization model (free vs ad-supported). Expo Go's advantage is rating (4.8 vs 4.6) and ratings volume (7.9K vs 575). On price, update cadence, in-app purchases and chart position there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Expo Go holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Expo Go has 7.9K ratings behind it against 575, so its average is the more settled of the two. Written reviews complicate that: 56% of Expo Go's written reviews are positive against 78% of a's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Expo Go ships an update fortnightly, a monthly. Both last shipped on November 11, 2026.
