The N26 app is garbage. Revolut is OK, but it's a money changing service, not a bank. I did a transfer from the Revolut account and it took 3 days. Topping up is fast because it charges your card, rather than doing a transfer.
The Transferwise borderless account is pretty good, at least I much prefer it to Revolut - since SEPA transfers happen same day, the app is better and the debit card is free.
