Have just tried MoneyDashboard given they are crowdfunding at the moment. The idea is great. I connected my Monzo account but they forgot to mention that it does not work with Monzo which I found out 20 hours after logging a support ticket. They say they are working with Monzo to resolve the issue but no time line. Looks like they do just not care that this a a critical bug. The issue strikes at the heart of Monzo instant advice as transactions are taken at the initial value in Monzo and not updated so all foreign, pay at pump petrol and hotel bills are all brought across at the wrong value. Pay at pump come across at £1 so in my case are some £50 to £60 short.
Monzo should them selves have a warning that their account just does not work with MoneyDashboard
