Do not use a N26 account
I decided to try the N26 account and found the software to not be user friendly. It was also difficult to confirm authorisation of transactions.
Have decided to cancel the account and having followed their procedure I am now battling against a non responsive system with monthly fees simply being added and my mails ignored or an apology with a promise of action. 3 months on and still no action other than automated response threatening legal action if I do not top up the account. 
My recommendation is leave well alone until they can administer Thier accounts.
