The bank's features are similar to other neobanks, in that the app is fast + generally works well, there aren't charges to make transfers (no charges for anything really), support is good, there are savings features built in, and so on.

The thing that sets Tomorrow apart is the good it does (that you do, by extension, as a customer). They use your money for good, instead of, for example, dirty energy. There are constant fundraisers for projects around the world. I like that a lot.
