Earlier this year my partner and I switched our joint account from Monzo to Starling simply because we both hated using the Monzo app. Navigating the app feels unnatural to us and probably due to how infrequently we use it, we never learnt to live with it.
Last week I finally closed my personal Monzo account as I only used it for one small DD a month and much prefer the Starling and NatWest apps.
