Where CrestCast is different
CrestCast is not a tracker. It is a forecaster. Instead of showing where your money is now, it projects where your household is heading across cashflow, profit & loss, net worth and debt over months and years, and lets you model the decisions that change that path: overpaying the mortgage, a pay rise, a new baby, one partner going part-time.
The other difference is philosophy: CrestCast never connects to your bank. You decide what it knows and nothing is pulled in automatically. Where Lumio's strength is the connected, present-day view, that is precisely what a lot of people would rather not have. Here is why I built it that way.
What Lumio is
Lumio is an app for couples who want to manage shared money together, and it describes itself as a virtual joint account for modern couples. It connects to your accounts through Open Banking, brings your spending, balances and net worth into one place, sets your assets against your debts, and helps you keep on top of shared household bills, with an IOU tracker so either of you can settle up on what the other paid. If what you want is a live, connected picture of the money moving through your accounts, that is what it is for.
Forwards, and with nothing connected
Figures shown are the sample profile, not a real household.
Which should you choose?
If you want to see and shape your household's financial future without linking any accounts, that is CrestCast. If you want a bank-connected app to track and manage shared spending day to day, Lumio is the natural pick. They are answers to two different questions, and some households happily use one for each.
If forecasting is what you are after, the couples and families overview is the best place to see how CrestCast fits, or jump straight into a calculator.
Common questions
›Is CrestCast a good Lumio alternative?
For the planning job, yes, and it is a job Lumio is not built for: CrestCast forecasts where your household finances are heading over the next ten years and lets you test decisions against that picture, with no bank connection anywhere in it. Lumio is the better fit if what you want is Open Banking aggregation and hands-on management of shared day-to-day spending. They answer different questions about the same household.
›Does CrestCast connect to my bank like Lumio does?
No, and that is deliberate. CrestCast never connects to any account. You enter what you want it to know, or import a CSV that is processed on your device, and nothing is pulled in automatically, so no bank credential is ever shared and the model holds exactly what you chose. Lumio works the other way: in its own words it is powered by Open Banking, and its pricing page offers unlimited bank connections on every tier. If you specifically do not want a bank-connected app, that is the difference.
›How much does CrestCast cost compared with Lumio?
30 days free, no card. Then £7.99 a month or £79.99 a year for the whole household. Checked on 16/09/2026, Lumio's own pricing page showed a free Individual tier, Pro Individual at £3 a month or £26.99 a year, and Pro Couples at £4.49 a month or £39.99 a year. The two are not doing the same job, so the comparison is not really about price: what the subscription buys is the forecast and the ability to compare decisions before you take them.
›What is the main difference between CrestCast and Lumio?
The job. Lumio tracks and manages the money a couple has and spends right now. CrestCast forecasts where the household is heading, as cashflow, profit and loss, net worth and debt payoff over months and years, and lets you model decisions (a pay rise, a new baby, overpaying the mortgage) before you make them.
›Can I use both?
Yes, and some people do. Tracking the present with a bank-connected app and forecasting the future with CrestCast are complementary rather than competing, and nothing has to pass between them.
