What can I say?
It’s fantastic! An incredibly helpful tool. I use it to practice small snippets of code when I’m laying on the couch or out somewhere. It’s great for reinforcing your learning when you’re away from the computer.

What's New in webrios
1.2.0
October 10, 2026
webRios 1.2.0 is here, and it's a big one: R 4.6, a Stop button, interactive plots, network access, and an editor that keeps up with you. NEW • You can now stop running code with a tap on Stop, or with Command-period, and your variables stay put. • webRios now uses webR with R 4.6.0, and offers to reinstall your R 4.5 packages in one tap. • Interactive plots from plotly, leaflet and DT now work, and any plot can appear right in the Console. • Your code can now reach the web with httr2 and curl, by default through a proxy that runs on your device. • R scripts, R Markdown, Quarto, .rds, .RData and CSV files now open in webRios from Files, Mail and other apps. • Each project can keep its own variables once you turn on Save Workspace. • A Getting Started checklist walks you through your first six steps. • On iPad, the File, Code, Run and View menus sit in the menu bar, with keyboard shortcuts throughout. IMPROVED • The editor stays fast in long scripts, and Command-Return steps through a script one statement at a time. • Code completion narrows as you type. • The data viewer opens large data frames quickly, then filters, sorts and searches them. • Browse describes every package, even offline, and saved packages load several times faster. • Help pages gain a Back button, tables and links between pages. • VoiceOver reads results and errors aloud, with labeled controls throughout, and the app respects Dynamic Type, Reduce Motion and Increase Contrast. Dozens of smaller refinements round out the release. webRios 1.2.0 requires iOS 26.
