UK money apps compared: spending tracker, budgeting app or forecast?

Snoop. Its budgets, in its own words, are a limit on your monthly spend and each spending category, tracked against last month: they sit on the feed, not ahead of it. It looks forward in two places, a timeline of bills against your balance for the rest of the month and Future You (iOS 11.3.1, 19/08/2026), which shows where your savings could be over 15 years based on your savings rules. Neither projects a household. Snoop says Future You is rolling out gradually; it is in the app listing, not on snoop.app, so check you can see it.

Emma. Net worth tracking is Pro and above. Asked what replaced Money Dashboard's Forecast feature, Emma answered with budgeting, True Balance and everyday balance. True Balance, in Emma's words, shows how much you would have left in an account after recurring and subscription payments: a cleaner statement of today, not a projection. Its Budgeting section plans a set period, usually a month.

Plum is an automated saver first: it learns from your past transactions how much to move into savings, the most backward-looking engine here and the right design for the job. It does project. Plum Plan, live on its site since at least June 2026, is a free AI roadmap to goals, retirement among them. Plum says projections are illustrative and not guaranteed and that it does not provide financial advice. It returns a number and a timeline, so it answers whether a goal lands, not what your balance does month by month, and it is built for one person: nothing on it describes a joint or household plan.

Monzo is a bank. Budgeting lives in Trends, which replaced Summary on 21 December 2025 and aggregates personal, joint and connected accounts. Its one forward number is how much you have got left to spend in this period, taking into account any payments due soon. Max is from £19 because it rises by £4 a month for family cover and has a three-month minimum. Monzo has closed Plus and Premium to new customers, so a page quoting their price describes something you cannot buy.

YNAB does not forecast balances, by position and not by gap. Its irregular-income guide has a section headed Why Forecasting Doesn't Work, which says YNAB are not big fans of forecasting, that it often leaves you in the rain without an umbrella and that it can result in a false feeling of financial control (checked on ynab.com on 16/09/2026). Its method is to give every pound you already hold a job, sound for someone overspending this month. CrestCast vs YNAB.

PocketSmith is the one product here that forecasts ahead in the same sense CrestCast does: it projects each account balance from its current balance by adding and subtracting your scheduled budgets, for six months on the free plan, ten years on Foundation, thirty on Flourish and sixty on Fortune. Per its documentation, balances are daily up to three months out and weekly beyond. It bills UK customers in pounds and has the bank feeds CrestCast does not. CrestCast vs PocketSmith.

Any projection longer than a month or two has to answer one more question: what happens when the account runs dry? CrestCast takes a rule you write once, a minimum to hold, an order to raid your pots in and where a surplus goes, and obeys it every month for ten years. That is the difference between a projection and a plan, worked through in why your forecast should not go overdrawn.

Moneyhub (consumer app closed 31/07/2026, export window shut: alternatives) and Money Dashboard (apps closed 31/10/2023; free, monetised by selling anonymised market research: CrestCast vs Money Dashboard) were switched off when the other revenue line stopped working. Ask who pays for the app you are about to put ten years of your financial life into, and whether it lets you get your data back out.

Every other app on this page connects to your bank and CrestCast does not. That means no automatic import, no categorisation, no self-updating balance, and typing before you see anything. It buys a model containing exactly what you chose, with no credential shared and no feed to break. The reasoning.

CrestCast also does not do retirement planning, models only the UK, and stops at ten years rather than thirty. If you need one of those, or PocketSmith's bank feeds, or YNAB's envelope method, they are the better answer.

Where did it all go? A spending tracker: Snoop free, Emma if you want subscriptions hunted down, Monzo Trends if you already bank there.

How do I stop overspending? A tracker for a feed with no typing, or YNAB if you will learn a method; give it a fortnight. CrestCast lets you log what really happened so the forecast re-reckons around the actuals, but there is no budget to drift from and it will not police your spending.

Can we afford this? You need a forecast, and the field is two products wide: PocketSmith for bank feeds and account-level balance projection, CrestCast for a UK household modelled as one thing across cashflow, profit and loss and net worth, with both incomes, the mortgage and the children in one picture.
