Free and flexible
No subscription, and you can shape rows and formulas exactly how you like.
A spreadsheet is free, familiar and flexible. A shared budget app is live, syncs itself and records who paid. The right choice depends on how many people need the same numbers.
A spreadsheet is a good budget for one person who enjoys maintaining it. A shared budget app is better for couples and households, because two people need the same live numbers: who-paid records are automatic, updates sync in real time, and there is only ever one version of the truth.
No subscription, and you can shape rows and formulas exactly how you like.
If you enjoy modelling scenarios and historical trends, a sheet is hard to beat.
You own the file and decide every detail of how it is structured.
A spreadsheet assumes a single maintainer and a single copy. The moment two people are involved, that assumption fails. Someone forgets to update it; the other edits an old version; the file is on one person’s laptop; the formulas break. Soon there are two spreadsheets and no shared truth.
The same jobs, and how each one holds up when two people share the numbers.
