a vs Last Seen Up

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.

Know the moment it stops answering. Last Seen Up watches your servers, sites, queues and cron jobs, and wakes you when something stops responding. Checks run on our servers around the clock, so the alert reaches you whether or not your phone is awake. ONE GLANCE, ONE ANSWER Open the app and the dashboard tells you in a single line whether everything is fine. When something is down, the dashboard becomes the incident: how long it has been down, what failed, a countdown to the next escalation step, and Acknowledge right there. Thirty days of history and upcoming renewals sit underneath. ADD ANYTHING BY PASTING IT Paste a website, an IP address or a host and port, and Last Seen Up works out what kind of check it needs and tests it while you type. A website is one monitor, not three: we check that it answers and keep an eye on its SSL certificate and domain registration, so the renewal you forgot is a reminder weeks out instead of an outage on a Saturday. CATCH THE JOBS THAT DIDN'T RUN A cron job that stops running fails silently. Give it a heartbeat URL to call when it finishes, and if the call never comes we tell you. The alert shows the last several runs at a glance, so a job that has been failing every other night for a week looks different from one that broke tonight. WILL IT ACTUALLY WAKE YOU? "Can we wake you?" checks whether this iPhone will really ring at 3am, and opens the right setting to fix anything that would stop it. Send yourself a test alert, or have us call you, to be sure. ALERTS BUILT FOR 3AM Alerts arrive as Time Sensitive notifications, so they break through a Focus. Long-press one to see how long it has been down and what failed, then acknowledge or snooze without opening the app. If nobody answers, escalation moves to the next person on your list, and the last step can be an actual phone call to a number you have verified. Quiet hours and do not disturb keep the rest of the night yours. ANYONE CAN SAY "I'M ON IT" Acknowledge from any iPhone you are signed in on, even when the alert went to a teammate. Everyone sees who has it, and escalation stops. WATCH IT UNFOLD An open incident puts a live counter on your Lock Screen and in the Dynamic Island, showing who is on it and what happens next, then ends with how long the outage lasted. Home Screen and Lock Screen widgets keep your worst monitor in view. ON YOUR WRIST The Apple Watch app carries the full roster. Acknowledge an incident or run a check with your phone in another room, and put your fleet's state on the watch face with complications. YOUR TEAM, FROM YOUR PHONE Invite teammates, switch workspaces, and set how often new monitors are checked, how many failures it takes to alert, and which alert policy they follow. BUILT NOT TO LIE TO YOU If the app cannot reach our servers it says so plainly rather than showing you a reassuring green screen. Status is never colour alone, so it reads correctly on a watch face, in sunlight, and with VoiceOver. FREE TO START Three monitors and everything above, free, with no trial and no card.
