iPhone
The no-frills habit tracker for impulse buying. DoNotBuy buzzes you at the door — before you walk in, before you swipe, before you regret it.
Every day you tell yourself: no more coffee. No more energy drinks. No more sweets — or worse. Hours later you're walking to the store on autopilot. You buy. You regret. You promise yourself... starting tomorrow. It doesn't work like that. You need an app that stops you before you walk in.
THE PROBLEM ISN'T WILLPOWER. IT'S TIMING.
Retail therapy doesn't happen because you're weak. It happens because no one interrupts you at the moment of decision. Budget apps and habit trackers log the damage AFTER it's done. DoNotBuy does the opposite: it puts itself between you and the checkout — with a notification at the door.
WHY TRADITIONAL APPS FAIL
They measure the pain. They don't prevent it. You log yesterday's $7 latte — and buy today's anyway. You see the number and nod. The app did its job. You lost money.
DoNotBuy interrupts the autopilot before the money is gone.
HOW IT WORKS
1. Pick the places that cost you — the corner store, the café by the train, the gas station at midnight.
2. DoNotBuy uses geofencing to know when you're nearby.
3. Before you walk in, your iPhone buzzes. A notification reminds you of your promise, your goal, your savings.
4. You walk past. Or you walk in. Both decisions get counted.
5. Every evening you see what today's "no" was really worth.
WHAT YOU'LL SEE
— A notification at the door, before you enter the shop.
— Every dollar you save, live on your dashboard.
— Real goals: vacation, car, wedding — or your own.
— Streetwear-themed achievements that show: the money stays in the bag.
— Daily check-ins and a streak heatmap that proves your consistency.
A NEW KIND OF HABIT TRACKER
DoNotBuy isn't another budget app. It's the no-frills habit tracker for the moment of decision — the dopamine detox you actually keep. Like Atomic Habits applied to your wallet. Like delayed gratification with a tap on the shoulder.
For people who take minimalist living, mindful spending, and shopping addiction seriously — without spreadsheets, without guilt, without bloat.
No accounts. No cloud. No subscriptions for features that should be free. Just a notification at the door, and the score at the end of the day.
PRIVACY
DoNotBuy stays on your iPhone. No accounts. No cloud. No tracking. No ads. Location data is processed exclusively on-device to trigger geofence notifications. Apple's StoreKit handles the subscription — we never see your Apple ID or purchase history.
