What's a good iOS app for keeping an eye on stock prices and crypto charts, especially when I'm stuck on a 12-hour shift and can only check my phone for a sec?

Okay, so TradingView is pretty solid for tracking stocks and crypto. It's like having a pocket reference guide, which is super useful during those crazy 12-hour shifts when I barely have time to breathe, let alone do any real research. I'm too tired to learn complicated apps, but this one has a no-fuss approach that I appreciate. I can quickly glance at charts and prices without getting lost in a million features I don't need. Plus, it's actually reliable – hasn't crashed once in the last six months, and that's saying something considering how many apps I've tried that just give up halfway through the day. It's not flashy, but it works when you need it, which is exactly what I need when I'm running around the hospital.
