The short version
YNAB suits people who want zero-based budgeting discipline; Monarch suits couples who want net worth and shared accounts in one dashboard. Neither models UK pensions, ISA allowances or long-term tax, which is where Delphina picks up.

Where YNAB wins
- The zero-based method genuinely changes behaviour for people who stick with it
- Excellent teaching material and an unusually loyal community
- One subscription covers up to six people
Where Monarch Money wins
- Genuinely good for couples and shared household finances
- Clean interface with strong net worth and investment tracking
- Subscription funded rather than advertising funded, and says it does not sell data
Where both fall short
- Neither applies UK tax rules to what it shows you.
- Both are built US-first, so UK users pay in dollars and work around US assumptions.
If neither is quite right
If what you actually want is the retirement answer rather than a better dashboard, that is the gap Delphina was built for: UK pensions, ISAs and tax, projected to the age you want to stop. It does not do the job YNAB does for people who want to change their spending habits and will do the weekly work, so if that is the real problem, YNAB is still the better buy. Free plan is £0, no card.
YNAB vs Monarch Money: common questions
YNAB is $109 per year and Monarch Money is $99.99 per year. Compare the billing period before the number: an annual price and a monthly price are not the same thing.
You can, and some people do, because they solve different halves of the problem. It does mean paying for both, so add the two annual figures together before deciding.
Judge it on billing currency, Open Banking coverage and whether ISAs and pensions are handled. Check each one against those three points, because a tool that scores well elsewhere can still be a poor fit in the UK.
YNAB suits people who want to change their spending habits and will do the weekly work. Monarch Money suits us couples who want one shared view of budgets and net worth. The one that matches how you already think about money will take less setting up.
YNAB scores 4.6/5 on Trustpilot from 3,054 reviews. Monarch Money scores 2.1/5 on Trustpilot from 24 reviews, on an unclaimed profile. Weigh the volume as well as the score.
Delphina covers the gap both leave, which is UK pensions, ISAs and tax projected forward to retirement. The trade-off is that it does not do the job YNAB does for people who want to change their spending habits and will do the weekly work, so if that is the real need, pick one of these two.
