P-REx: Parameterized Runtime Execution

I just wanted to run one function.
RStudio didn’t open. My Wi-Fi connection disappeared. Cookies were required — tragically, not the snacking kind.

So I made this.

It’s a lightweight R console for your iPhone. No cloud. No account. No add-ins. Just R, running offline, like it’s 2004 and deep focus was still fashionable.

Whether you’re simulating data from the couch, calculating probabilities at 35,000 feet, or panic-testing t.test() before an important meeting, P.REx shows up quietly and does the math. Like a stats TA who won’t judge your p-value or your life choices.

What it does:
• Runs core R functions — over 99 of them
• Offline, because life happens
• Remembers your variables, even if you don’t
• No ads, no feeds, no helpful tooltips that aren’t
• Works on planes, trains, and late-night study spirals

I built it to run one line of code.
Now I use it to avoid everything else.
