With overdrafts currently unavailable from bunq I looked at what other options were available from app only banks in the UK. One bank, with plans to expand soon to Ireland, have an in app overdraft that is really well done.
It is intuitive to set up and it is very clear what you are getting and how much it will cost. A huge plus I feel is that at any time you can see in your app how much interest you have incurred that month, that is seriously lacking (both in app and in internet banking) with big banks, at least in the UK.
They also have an online calculator on their homepage comparing their overdraft with other banks, being open and honest showing when they cheaper and when they not.
I am not sure if overdrafts are on the bunq wishlist, but if they are then I think following that same approach and showing a comparison of rates against the main banks in NL, UK, DE, FR, ES, IR, etc would good so bunq customers can compare with their local alternatives.
