What are the best apps for expats?

For expats, I'd recommend Google Translate for quick language help, Meetup to find local events and connect with people, and TransferWise (now Wise) for easy international money transfers. Also, Duolingo is great if you're picking up a new language! These make adjusting to a new place much smoother.

I will make a list of feww apps here
Google Translate - Handy for translating signs, menus, documents on the fly. Works offline too.
Maps.me - Useful offline maps app for navigation if you don't have data. Works worldwide.
XE Currency - Checks current exchange rates for transferring and spending money.
Uber - International ride-hailing service helps get around unfamiliar cities.
Airbnb - Rent unique accommodations when traveling within a country.
Google Fi - Affordable international calling and data plan if you need a US number abroad.
Spotify - Listen to music online or offline anywhere in the world.
Expat Explorer - Connect with other expats, find jobs/housing, events in your new city.
WorldRemit - Affordable way to wire money back home from abroad.
