Sunday night. The account says one number.
The spreadsheet nobody updated says another.
And rent, groceries and the car payment are all due.
You don't need a bigger, better app. You just need to know what every dollar does and where it goes.
Three things your budget app should help you do.
Track when money comes in
Tell Sidecar about your paycheck once. Fixed amounts for the bills that don't move, percentages for everything else. It posts on the day and divides itself.
Give every dollar a job
Rent, groceries, petrol, the school run. Each envelope holds a real number, and that number is what you have.
Help you spend without guessing
Standing in a shop, you open the envelope and the answer is already there.

This is the whole app.
Seven screens. Keep scrolling and you'll have seen all of them.
HomeEvery dollar gets a job.
EnvelopesSee what's left before you spend.
PaycheckDivide your pay automatically.
ScheduledBills and paychecks post themselves.
AddSplit one shop across several envelopes.
ActivityAnd see exactly where it landed.
ReportsWatch where it actually goes.
