It is the question most people never quite get to the bottom of. Here the two tools are genuinely different. Quartz is built around wealth and investments rather than budgets. Delphina includes spending and budgets as part of the wider picture.
A wealth tracking platform
Quartz connects your current accounts alongside your savings and investments, so your cash sits within your wider wealth picture. Quartz describes its focus as your wealth as a whole rather than day-to-day spending, and at the time of writing it does not advertise budgeting tools.
For people who want to focus on growing and tracking wealth rather than on everyday spending.
A financial clarity platform
Add your UK bank accounts. The dashboard lays out your spending in clear charts, surfaces cash flow, and lets you set category budgets with spending limits.
For people who want to see their spending laid out in front of them and are happy to enter their own data.

If budgeting matters to you, pick a tool that does it. If you already have spending sorted, the choice is about the rest of your picture. Try both and see which fits.
Delphina is free to start. Quartz offers a 14-day free trial, then £16.99 a month or £169.99 a year.
