What's a grand iOS app for buying crypto and keeping an eye on it while I'm backpacking around Southeast Asia?

Honestly, Crypto.com has been an absolute godsend. I needed something that worked globally, especially in places where the Wi-Fi's a bit dodgy, like when I was trekking in Nepal. It works a treat, even with a slightly weaker signal, and doesn't eat up your roaming data like some apps do. I can buy Bitcoin, CRO, and all sorts, plus keep track of my investments without constantly worrying about getting stung by mad transaction fees. It's dead easy to use, which is a massive bonus when you're jet-lagged and trying to figure out local currency rates. I've even used it to pay for stuff in a few places that accept crypto directly. Definitely recommend it if you're travelling and want to stay on top of your crypto game.
