You're sitting in a coffee shop with nothing but an iPad Pro and a sudden urge to run a random forest model on a 500MB dataset. It sounds like a dream, right? The thin glass slab is powerful, the M4 chips are screaming fast, and the battery lasts all day. But then you realize Apple's "walled garden" feels more like a prison for anyone trying to use the R programming language iPad users have been begging for.
Honestly, the situation is messy. It’s a mix of "yes, but" and "no, unless."
Apple’s iPadOS is fundamentally allergic to the way R usually works. R wants to live in a terminal. It wants to manage packages through CRAN. It wants to compile C++ code via Rcpp. iPadOS, meanwhile, wants everything to be a sandboxed app with strict permissions. This friction defines the entire experience of trying to do data science on a tablet. You aren't just fighting the code; you're fighting the operating system itself.
The Local Reality: Can You Run R Without Wi-Fi?
If you're looking for a native, double-click-to-open RStudio app for iPad, stop looking. It doesn't exist. Posit (formerly RStudio PBC) hasn't made one, and they likely never will because of Apple’s App Store policies regarding interpreted code and execution environments.

However, there is Carnets.
Carnets is a fascinating project by Nicolas Holzschuch. It’s a complete, standalone Jupyter notebook environment that runs locally on your iPad. It actually includes a full R distribution. You can install packages, though you'll occasionally hit a wall if a package requires complex system-level dependencies that haven't been ported. It's the only way to do R programming language iPad work while you're 30,000 feet in the air without paying for plane Wi-Fi.
The downside? It feels clunky. If you’re used to the four-pane glory of RStudio, shifting to a notebook-style interface feels like trying to write a novel on a typewriter when you’re used to Microsoft Word. It works for quick visualizations or basic statistical tests, but I wouldn't want to build a shiny app in it.
The Cloud is Your Best Friend
Most professionals I know who use R on an iPad don't actually run R on the iPad. They use the iPad as a portal. This is where Posit Cloud (formerly RStudio Cloud) comes in.
It's essentially RStudio in a browser. Since it’s running on a remote server, the iPad’s hardware doesn't matter. You could be using a base model iPad Air or the most expensive Pro; the performance is identical because the "heavy lifting" happens in a data center somewhere in Virginia or Dublin.
- Sign up for a free or paid Posit Cloud account.
- Open Safari (or better yet, save the page to your Home Screen to get rid of the browser UI).
- Log in.
- Boom. You have RStudio.
There is a catch, though. Safari on iPadOS is... temperamental. Occasionally, the virtual keyboard will cover the console, or the cursor will jump around in the code editor. It’s about 90% of the way to a perfect experience, but that final 10% of friction can be maddening during a long coding session.
The Power User Way: SSH and VS Code
If you’re a bit of a nerd, there is a much better way. It’s what I call the "Headless Server" approach.
You buy a cheap VPS (Virtual Private Server) from DigitalOcean or Linode for $5 a month. You install R and code-server (the web-based version of VS Code) on it. Then, you use an app like Blink Shell or Screens on your iPad.

Blink Shell is the gold standard here. It’s a pro terminal for iPadOS that supports VS Code natively. When you connect your iPad to your server via Blink, you’re basically getting a full-blown IDE experience. You can run R scripts, view ggplot2 outputs, and manage your files as if you were on a Linux laptop. It’s fast. It’s stable. It feels like the future.
Why the Hardware Matters (But Not Why You Think)
You might think the M2 or M4 chip is the reason to buy an iPad for R. It isn't. You can't use 99% of that power because of the software limitations. The real reason to get a Pro for R programming is the Magic Keyboard and the Stage Manager support.
Trying to code on a touchscreen is a special kind of hell. You need the trackpad. You need the physical keys. And more importantly, you need to be able to have your R environment open on one side of the screen and a Stack Overflow tab (or ChatGPT) open on the other. Stage Manager, despite its critics, makes this possible.
The Package Problem: Why Some Things Just Break
Let’s talk about tidyverse. It’s the bread and butter of R. On a local iPad app like Carnets or a-Shell, installing tidyverse can be a nightmare. Why? Because tidyverse is actually a collection of packages, and many of them—like stringr or dplyr—rely on underlying C++ or Fortran code.
On a Mac or PC, your computer just compiles this. On an iPad, you can’t just "compile" things willy-nilly. The app developer has to have pre-compiled these libraries for the ARM architecture of the iPad and included them in the app bundle. If you need a niche package for spatial analysis like sf or terra, you are almost certainly out of luck with local execution.
Real World Use Case: The "Field Researcher"
Imagine you're an ecologist. You're out in the woods. You need to log data and run a quick linear regression to see if your sample size is sufficient.
- Option A: Bring a bulky MacBook Pro that you’re afraid to drop in the mud.
- Option B: Bring an iPad with a rugged case and use Carnets.
In this specific scenario, the R programming language iPad combo wins. You collect the data in a CSV, import it into Carnets, run summary(lm(y ~ x, data = df)), and you have your answer in seconds. No internet required.
Is it worth it in 2026?
Honestly, if you are buying an iPad specifically to be your primary R machine, don't. Just get a MacBook Air. It’s cheaper than an iPad Pro + Magic Keyboard combo, and it runs R natively without any of these headaches.
But if you already own an iPad and want to use it for data science on the go, it’s totally doable. You just have to accept that you're going to be working in the cloud most of the time.
Actionable Steps for Setting Up R on Your iPad
If you want to start today, don't waste time experimenting with every app in the store. Follow this path:

- Get a Keyboard: Don't even try without one. The Logitech Combo Touch or Apple Magic Keyboard are the best bets.
- Start with Posit Cloud: It’s the easiest way to see if the workflow fits your brain. Open it in Safari, use the "Add to Home Screen" feature, and try to run a script you’ve already written.
- Download Blink Shell: If you find the browser experience too laggy, invest the money in Blink Shell and set up a small Linux server. This is the "pro" move.
- Install Carnets: Keep this on your device for those moments when you have no signal. It’s your emergency R environment.
- Use Tailscale: If you’re running a server at home, use Tailscale to securely connect your iPad to your home desktop. You can then access your "real" RStudio instance from anywhere in the world.
The iPad isn't a replacement for a computer when it comes to R; it’s an extension of one. It’s about being able to tweak a plot while you’re on the train or checking the results of a long-running model while you're lying on the couch. It’s liberating, as long as you know where the walls are.
The "walled garden" is still there, but the gates are starting to creak open. For the R user, that’s just enough room to get some real work done.
Next Steps for Your Setup
- Check your most-used packages: Go to the CRAN page for your top 5 packages and see if they require significant system dependencies (like GDAL or GEOS). If they do, lean toward the Cloud/SSH approach.
- Test the "Add to Home Screen" trick: This removes the address bar in Safari, giving you about 15% more vertical screen real estate for your R console.
- Explore Quarto: If you're using your iPad for reporting, R's Quarto (the successor to R Markdown) works beautifully in browser-based editors and is perfect for the iPad's vertical orientation.
