Smart Spend Tracking
Transactions sort themselves into clean categories the moment they land, so you always know where the money went.
Addtivity Command · Lifestyle App Suite
Every dollar,
finally in focus.
Addtivity Finance turns scattered spending into a single clear picture — free on your Windows desktop today. The mobile app is coming soon, with macOS and Linux on the same foundation. No spreadsheets. No guesswork. Just activity you can actually see.
Not on Windows yet? Be first to hear when your platform is ready. No spam, ever.
“Add to activity, since the only way to add is to be active.”
What it does
Built to make money make sense.
Real-Time Insights
Visual breakdowns of spending patterns update the moment they happen — no waiting for a monthly statement.
Goals & Budgets
Set a target, watch the bar fill, get a nudge before you go over — budgeting that feels like progress, not punishment.
Your Desk Today, Your Pocket Next
Windows today. The mobile app is coming soon, with macOS and Linux built on the same foundation. One account carries your preferences everywhere — your books stay on your machine.
Private by Architecture
Your receipts, transactions and balances live on your own computer — we never hold a copy, so there is nothing of yours on our servers to sell. It's your activity — it stays yours.
Try it yourself
The actual app, drawn in your browser.
Not an impression of the product — the real window and the real phone screens, with the same theme, the same navigation and the same two pages you land on. Dashboard and Budget are here; everything else is in the download. The figures come from the apps' own demo dataset, so no real record is on screen.

$388 a day is safe for the rest of the month.
$11,367 in ($2,842 so far, $8,526 still expected) · $159 spent · $525 of bills still to land · $600 being set aside.
This is income less what has gone, less the bills that have not landed yet, less what you are setting aside for goals. It is smaller than “income minus spending” on purpose — that figure is cheerful on the 3rd and wrong by the 28th.
🔮︎
On pace to spend $823 this month — within the $11,367 expected in.

Both replicas are drawn from the apps' own theme files, and every figure comes from the demo datasets that ship inside them — the Windows window uses the same seeded records as the screenshots on our company site, and the phone uses the Marlowe household story. Nothing here is a real person's money.
Why it's safe to try
Your money data, handled with care.
Yours, on your machine
Your financial records live in a database on your own computer. We cannot read them — we never have a copy.
Read-only connections
Linked accounts are viewed, never moved. Addtivity Finance can't initiate transfers.
We don't sell data
No ad networks, no data brokers. Your activity is not the product.
You're in control
Disconnect any account or delete your data permanently, any time.
Pricing
Start free for 14 days.
Every install begins with a fortnight of the whole app, then settles into Basic. Payments aren't switched on yet, so today every tier below is free to download and use — the prices are here so nothing is a surprise later. And when a trial or a plan ends, everything you've filed stays readable forever: limits only ever stop new additions.
