Recurring expenses
The bills and subscriptions that come back every cycle. Rent, power, the gym, Netflix. Lined up on the day they actually leave your account.
iPhone · Made in Brisbane
Your money,
fortnight clear.
I built fourtn. to answer one question: how much can I actually spend before my next pay? It puts your bills, one-off costs, cards, and buy now pay later plans on your real pay cycle, then shows what's left.
What it tracks
Four things, all on your pay cycle.
Pick weekly, fortnightly, or monthly. fourtn. does the calendar maths, so you see what's left before payday, not the morning after.
One-off payments
A single upcoming cost, like a rego or a birthday. As you type it in, you watch your leftover update live before you commit.
Cards
Keep your card balances in plain sight, so a quiet limit doesn't quietly turn into next month's loud surprise.
Buy now pay later
Afterpay, Zip, and the rest. Every instalment sits next to everything else, so future you isn't caught out by past you.
No accounts. No cloud. No tracking.
Your numbers never leave your phone.
Why it's private
Private because there's nowhere for your data to go.
There's no server to leak and no login to steal. I can't see your data, because it never reaches me in the first place.
01
On your device
Everything you enter lives on your iPhone. Delete the app and it's gone with it. There's no copy anywhere else.
02
No accounts
Nothing to sign up for and nothing to log into. No email, no password, no profile sitting on a server.
03
No bank links
fourtn. never connects to your bank. You type in what matters, so there are no logins or account numbers to leak.
04
No tracking
No analytics, no ads, no tracking pixels. The App Privacy label says "data not collected", and it means it.
Price
Free. Tip if it helped.
The app
FreeEvery feature, no paywall
Download it, plan your pays, keep it. There's no subscription and nothing locked away behind a wall waiting for your card.
Optional
TipsHandled by Apple, anytime
If fourtn. saved you a headache, there's a small tip jar inside the app. Completely optional, and it never unlocks anything.
From the developer
Hi, I'm building fourtn. on my own in Brisbane, on nights and weekends. I wanted a calm, private way to see what I could actually spend without handing my bank logins to anyone or being sold to advertisers. No investors, no growth team, no dashboards watching what you do. Just an app I wanted to exist, made with a fair bit of care. If it helps you the way it helps me, that means a lot.
Made with care in Brisbane, Australia.
