UK households that use envelope budgeting and want to reconcile variable bills and direct debits against fixed monthly allocations without relying on spreadsheets.
How it works
- Create budget envelopes by selecting a predefined UK household category and setting a monthly allocated budget.
- Log direct debit or variable expense transactions against an envelope, specifying amount, date, and description.
- Edit or delete transactions and filter the transaction history by date to review past spending.
- View the dashboard showing total budget, total spent, remaining balance per envelope, and a category breakdown, plus an inflation-adjusted trend chart based on a manually entered inflation rate.
What you gain
- See exactly what is left in each envelope at a glance.
- Reconcile direct debits and variable bills against fixed monthly allocations.
- Edit or delete transactions and filter history by date for accurate records.
- Understand how inflation affects spending with a nominal vs real comparison.
- All data is saved automatically for future sessions.

Frequently asked questions
Is my budget data safe if I close the browser?
Yes, every envelope, transaction and inflation rate you enter is saved automatically on the server, so it's still there next time you open the app.
Does this connect to my bank to import direct debits automatically?
No, you enter each transaction manually. This keeps the tool simple and means it never needs access to your bank login.
What does the inflation-adjusted trend actually show?
It compares your raw (nominal) spending against what that spending is really worth after applying the inflation rate you entered, so you can see if your budget is losing purchasing power over time.
