Tandem just launched
A couple of highlights -
The startup will launch the app in waves to 10,000 early adopters
Users will initially be able to add any existing UK bank account to it. They can then monitor their spending and will receive suggestions as to how they can save money, stashing their Tandem’s own savings account, its first financial product.
So another app offering these ‘solutions’ 
but at least they have products to offer
Tandem’s own current account, loans and credit cards will also soon follow.
I’d still rather have a choice of all provider’s products.
It has raised £22m
Then some incorrect figures for no. Monzo users
Monzo was granted its banking license in August with imminent plans to launch a current account in the coming months. It already boasts more than 30,000 beta users of a pre-paid debit card
(it’s actually over 65k now so the speed of growth is picking up 
)
But CityAM didn’t allow me to post that comment & link
