It works offline and needs no account. RUN YOUR CODE β€’ Python, JavaScript, HTML and SQL run on the device, offline, from the moment you install. There is no run counter. β€’ Program input: type what your program reads with input() or prompt(), then run. Exercises that read input work too. β€’ Output appears when your program finishes. Stop a run at any time. β€’ HTML opens as a live page, with its CSS and script. β€’ SQL runs on a database on the device and shows the results as a table. ERRORS YOU CAN FIX β€’ Errors show the line they came from. β€’ Tap an error to jump to that line in the editor. β€’ A program stuck in a loop stops at the time limit, so the app stays usable.
