Impulse spending tracker for iPhone and Android
Quitzilla counts the time since your last impulse buy, totals what you didn't spend and lets it fill up a reward you picked ahead of time.
Add it up
Set the day of your last impulse buy, then a rough daily figure for what those buys cost and the minutes you spent browsing for them. A $50 order once a week works out to about $7 a day.

Example amounts. Change them to match yours.
The opposite of an impulse buy
A Quitzilla reward is something you decide on first and give a price. Your savings fill it up, and you buy it once it's ready. For example:
Inside Quitzilla
Sale countdowns, free shipping thresholds and saved cards make buying quick. Quitzilla doesn't block anything. It gives you something to look at first: your own reasons, your diary and the streak you're on.
Reasons to Quit
A sample list. Yours is up to you.
Quitzilla suggests four reasons for Impulsive Shopping, and every one can be reworded or replaced. Read them when a sale email lands or your cart is one tap from checkout.
Diary noteSale email on payday, and I bought a jacket I didn't need. Unsubscribed from that store tonight.
Log the purchase in the diary as a relapse; there's a field for what it cost. The count begins again from the time of the entry, and your earlier stretches stay on record. Closed the tab instead? Write that down too: a note without the relapse switch keeps your timer running.
Abstinence Periods gives every stretch without an impulse buy its own bar, with the current one last, and shows what each one saved. Spending lines up the amounts you logged at relapses, purchase by purchase. Charts are part of Premium.

Quitzilla puts a clock and a price on the habit. Add Impulsive Shopping, enter when your last impulse buy was and roughly what those purchases cost you, and keep the suggested reasons that fit. After that, Quitzilla times your streak to the second, keeps a running total of what you didn't spend and sets the next goal whenever you reach one. If spending has left you with debt that worries you, a debt advice service where you live can help you work out a plan.
You decide, and it helps to decide before you start. It could be anything that wasn't on your list, every online order, or any unplanned purchase over an amount you set. Quitzilla doesn't see what you buy: it isn't connected to your bank or cards and doesn't block stores or shopping apps, so you log a slip yourself. If the Impulsive Shopping template doesn't fit, add a habit under your own name for it, such as Online shopping or Late-night orders.
It doesn't see your spending, so it works from your own estimate. Think back over a typical month of spur-of-the-moment buys and enter what they cost per day, week or month, whichever is easier. Quitzilla multiplies that by how long it's been since your last impulse buy, so the total grows day by day. Nothing moves between accounts; the total lives only in the app. When you want to spend some of it, add a reward with a name and a price, and your balance counts toward it until it's covered. Time works the same way, and those hours can go into investments you name, such as Reading.
Log it in the diary as a relapse and, if you want, enter what you spent. The timer restarts from that moment, and the current goal with it. Earlier stretches, your longest included, stay in Statistics. Note the setting, say a countdown banner, a long day or scrolling in bed, and later those entries may tell you which moments to watch for.
