A multi-currency app account carried me through every newcomer gap I've had. The one thing I'll say: keep a second provider as backup, because verification hiccups or a frozen account at the wrong moment can leave you stranded if you've put all your eggs in one app.
Before my local account came through I leaned on an app-based bank to survive the first weeks, but they're not all equal — some choked on verification, some had rubbish exchange rates, some froze funds at the worst moment. Which one actually carried you through the newcomer gap, and where did it let you down?
