iOS 18 hidden feature! iOS 18 introduces significant enhancements to key iPhone apps like Messages, Photos, and Maps, but one of the most practical upgrades comes in the built-in Calculator app. Previously, the Calculator was just a standard tool (offering basic and scientific functions), but with iOS 18, it transforms into a versatile conversion tool for units and currencies, simplifying tasks like figuring out if you can afford to spend €100 on a new pair of shoes.
For example, if you’re curious about how much five British pounds equates to in US dollars, simply enter “5” in the Calculator (as though you’re inputting a sum), tap the calculator icon at the bottom left of the screen, select the “Convert” option, and then choose the currency you want to convert to. Voila! Now you’ll see that £5 may be a bit much for an Iced Matcha Latte from Blank Street Coffee-even in London.
To convert other units, tap the currency abbreviation, scroll through the list to find the unit you need, and follow the same steps for the second figure. Whether it’s currency, weight, or length conversions, this new feature is a must-have for frequent travelers or anyone needing quick conversions.
iOS 18 hidden feature! New Math Notes Feature in the Calculator App
Beyond its new conversion function, the Calculator app also now includes a “Math Notes” feature (labeled as “Maths Notes” in the UK). This feature allows users to write down equations, assign variables, draw diagrams, and plot graphs directly in the app. As an added benefit, the iPhone will solve your equations in real-time when you enter an equals sign, making it a useful companion for homework or quick math tasks.
In iOS 18, the Calculator app has gone from being a basic utility to an all-in-one math and conversion tool, helping with everything from daily expenses to complex equations.
