The Bad News: The Native App
Unfortunately, Apple’s built-in iOS Calculator app does not have a one-click decimal-to-fraction button.
Even if you rotate your phone sideways to open Scientific Calculator mode, Apple has not included a fraction key (like the S⇔D or MATH>Frac buttons found on physical calculators). It exclusively outputs in decimal format.
