Python Code Cards vs Termpolis R

Try the Python code you just found, right on your iPhone or iPad. See why it works by stepping through it. Python Code Cards combines an offline Python 3.14 runtime, an editor, and a step debugger with a notebook for your small code experiments. MADE FOR SMALL EXPERIMENTS • Check a snippet while reading a tutorial • Follow a loop or branch and inspect changing values • Keep useful code with your own notes START WITH CODE THAT ALREADY RUNS Five editable samples include FizzBuzz, Fibonacci, Binary Search, Bubble Sort, and Recursive Factorial. Change a number or condition and compare the results. This is a place to run and explore code, rather than a course or quiz app. PAUSE A LINE. SEE THE VALUES. Set breakpoints from line numbers. Continue, pause, step over, step into, and step out. Inspect variables, watch expressions, the call stack, and output as you debug. KEEP EACH EXPERIMENT AS A CARD Add code cards and notes. Edit, duplicate, collapse, and reorder them. Source, breakpoints, watches, and recent results stay together on your device. WRITE AND CHECK WITH LESS FRICTION Python syntax highlighting and local completion for keywords, built-ins, and symbols in your code. See standard output, exception lines, execution time, and resulting variables. Choose System, Light, or Dark appearance and switch the interface among 10 languages. NO ACCOUNT. NO ADS. NO TRACKING. The core app works without an internet connection. No analytics, tracking, or cloud sync. Cards and settings remain in local app storage and are not automatically sent to the developer. WHAT IS INCLUDED The bundled Python standard library is supported. Installing third-party packages with pip, AI completion, and cloud execution are not supported. Normal execution has a time limit.

Termpolis Remote is a companion for the Termpolis desktop app. It lets you check on the terminals already running on your computer, read what they have printed, and type into them, from your phone. It is a viewer and a keyboard. Nothing runs here. The work happens on your desktop, signed in the way it was already signed in, on the machine where your files, your repositories and your tools already are. Close this app and the work carries on without it. REQUIRES THE TERMPOLIS DESKTOP APP Termpolis Remote does nothing on its own. You need Termpolis running on a Mac, Windows or Linux computer, with Remote turned on in Settings. Termpolis is free and open source: github.com/codedev-david/termpolis RELAY ACCESS IS A SUBSCRIPTION The app is free to install. Your phone reaches your desktop through a relay we run and pay for, and that is what the subscription covers: Relay access -- $4.99 per month, auto-renewing. New subscribers get the first week free. The desktop app stays free and open source. There is no free tier here and nothing is held back from subscribers; the relay is the one thing this app does. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of that. Manage or cancel it in your Apple ID account settings after purchase. Any unused part of a free week is forfeited when you buy a subscription.

You scan it. Both screens then show the same eight words -- if they match, the two devices agreed on a key nothing in between can derive. If they do not match, something is in between, and the right move is to unpair. ONE PHONE, SEVERAL DESKTOPS Pair with up to 16 computers -- a work machine, a home one, a Linux box in the corner -- and switch between them from the terminal list. Each pairing has its own key and its own name, so each desktop grants what this phone may do on that desktop alone, and unpairing one leaves the others exactly as they were. END TO END, NOT JUST IN TRANSIT Every message between your phone and your desktop is sealed with a key the two of them derived together, using X25519 key agreement and ChaCha20-Poly1305. The relay that carries the traffic sees a room id, a size and a time. It cannot read a single byte of what passes through it, and it keeps nothing. YOUR DESKTOP DECIDES WHAT THIS PHONE CAN DO Reading output, starting terminals, typing, closing terminals -- each is granted on the desktop, in Settings, and each is checked again on the desktop for every request. This app can report what it has been allowed. It cannot grant itself anything. WHAT IT STORES One encryption key and one pairing record for each desktop you have paired with, in the iOS keychain, on this device only. No transcript, no scrollback, no cache of what your desktop said. Unpairing erases that desktop's key and record, and works whether or not the desktop is reachable. WHAT IT DOES NOT DO No account. No sign-in. No analytics, no crash reporting, no advertising identifier, no tracking of any kind. There is no server of ours that your terminal output ever reaches, because there is nowhere for it to go. CAMERA Used for one thing: reading the pairing code on your desktop screen. Frames are decoded on the phone and thrown away. If you would rather not, the pairing code can be typed in by hand. Termpolis is open source under the Apache 2.0 licence, and the wire format this app speaks is published in full.
