iPhone users have been left amazed by a hidden feature in the Calculator app that allows them to convert currency on the go, without needing an internet connection or third-party apps. TikToker Bianca Montalvo (@biancamontalvo) recently shared a video demonstrating the feature, calling it a game-changer for travellers.
In the viral clip, she explained: “If you’re travelling internationally this next year, you need to know this new iPhone trick to make your trip so much easier.” The process is simple: open the Calculator app, tap the icon in the lower-left corner, and toggle the currency option.
From there, users can enter amounts and instantly convert them into different currencies, perfect for keeping track of spending abroad without fumbling through multiple apps.
One of the most impressive aspects of this built-in converter is that it works offline.
This means travellers don’t have to rely on Wi-Fi or use expensive mobile data to check exchange rates, making it a more convenient and cost-effective alternative to traditional currency converter apps.
Apple quietly rolled out this feature in a recent iOS update, but many iPhone users had no idea it existed.
Since Montalvo’s video, which has gained thousands of views, users have been quick to praise the trick.
One user said: “I sounded like the ‘what? No way!’ guy watching this.” A second added: “Going to Japan in two months and this feature will save me from so many headaches. Thank you for bringing it to my attention.”
Another user even added that this trick could be useful for converting other metrics as well, saying: “It also converts other things like Miles to Kilometers and pounds to kilos! Also helps with international travel.”
With millions of people travelling every year, this discovery is set to make foreign transactions smoother and stress-free.
