I've used N26 for 6 months now in Germany and I never needed another account. It's a great app that surpasses the other by years. 
Sometimes I need stamped documents due to some bureaucracy and thanks to the perfect support service I get them as requested.
There's only one thing you should work on which is the Bank statement downloaded as PDF, all you provide is a very long list of transactions not a proper summarized statement about the current balance, I hope you'll consider improving this.
Thank you for everything.
Kind regards.
