Envelope budgeting made simple
Every dollar
gets a job
Sidecar is budgeting for people who want to know what they can actually spend. No bank connection. No ads. No tracking. Just a number on the screen instead of a guess.
Free to use · No account required to look around
How it works
Not one balance.
A place for everything.
- 01
Money comes in
A paycheck lands. Instead of one balance you have to interpret, Sidecar splits it the way you decided once — fixed amounts for the bills that don't move, percentages for everything else.
- 02
Every dollar gets a job
Rent, groceries, petrol, the school run. Each envelope holds a real number, and that number is what you have — not what's left in the account until the next bill clears.
- 03
You spend without guessing
Standing in a shop, you open the envelope and the answer is already there. Nothing to reconcile, nothing to project, nothing to hope about.
Inside the app
Seven screens. No clutter.
Everything Sidecar does, and nothing it doesn't.
Every dollar gets a job.
The part nobody else advertises
We never see
your bank.
Every figure in Sidecar is one you typed. That takes a few seconds a day — and in exchange, your financial life isn't sitting in one more third party's database.
No bank connection
Nothing imported, nothing synced, and we never ask for banking credentials.
No analytics, no trackers
No advertising SDK, no third-party trackers, no advertising identifier.
No ads, ever
Nothing in the app is trying to sell you something else.
Delete it all, any time
Export to CSV and delete your account from Settings. It goes immediately.
Built for two
One budget.
Two phones.
Most budgets fail because only one person is keeping them. Share yours and the arithmetic stops being one person's job.
Both of you see the same numbers, updating live.
Log a shop on the way home and it's on their phone before you are.
Owners invite and remove; remove someone and their access ends immediately.
Reports
Watch where it
actually goes.
Spending by envelope over a week, a month, or a quarter, with money in and money out side by side — and this period measured against the last.
