How it works

Ten minutes to set up. Then a minute or two each payday.

1

Tell it the basics

How you're paid, your bills and your debts. Rent, council tax, phone, cards, loans: whatever you've got.

2

Type in your wages

On payday, enter what landed. It splits it into bills, extra off debt, savings, a safety net and spending money.

3

Tick it off, watch it fall

Move the money, tick each one. Direct debits tick themselves. Your debts go down and your debt-free date gets closer.

🧾

Five ways to clear debt

Snowball, avalanche, focus on one, build a buffer first, or a bit of both. Switch any time.

📈

Interest included

Adds an estimate of each month's interest, so you see how much of your payment actually comes off.

⏰

0% deal alarm

Warns you before a 0% card deal ends, so the interest doesn't sneak back.

✅

Direct debits tick themselves

Automatic payments mark themselves paid on the day. Tick the rest as you go.

🔒

Your money stays your business

Debt Slayer never asks for your bank login, and everything you type stays on your own phone or laptop. We can't see it, and nobody else can either. Add a PIN lock if you share a device, and save a backup file whenever you like.

Questions

Can I try it first?

Yes. Open the free demo: the real app with example data, so you can enter a payday, tick things off and see your debt-free date. Nothing you change is saved, and a few extras (backups, reminders, PIN lock) come with the full version.

What do I actually get?

A link to the Debt Slayer app and your unlock code. Open the link on your phone, tablet or laptop, type the code, and you're in. You can add it to your home screen so it works like any other app, even with no signal.

Does it work on iPhone and Android?

Yes, both, plus laptops and tablets. It runs in your web browser, so there's nothing to download from an app store. On iPhone, open it in Safari and tap Share, then Add to Home Screen.

Is it a subscription?

No. You pay £14.99 once. No monthly fee, no trial that turns into a charge, no paid upgrades.

Do I need to connect my bank?

No, and it never will. You type in your wages and balances yourself. It takes a minute, and it means nobody has access to your bank account.

I'm not in the UK. How much will I pay?

£14.99, charged in pounds sterling. Your bank converts it to your own currency at checkout, the same as buying from any UK shop.

Does it work where I live?

Yes, if you're in the UK (England and Wales, Scotland or Northern Ireland), Ireland, the US, Canada, Australia or New Zealand. It uses your currency and your bank holidays, and links to free debt help in your country.

I'm paid weekly / every 4 weeks / twice a month. Will it work?

Yes. It handles weekly, fortnightly, 4-weekly, twice-a-month and monthly pay, including "last working day of the month", and moves payday earlier when it falls on a weekend or bank holiday.

What happens if I change phone?

Save a backup from Settings and open it on your new phone. It's one small file you can email to yourself or keep in your cloud storage.

Is this financial advice?

No. Debt Slayer is a calculator to help you plan, and the interest figures are estimates. If you're struggling with debt, free and confidential help is available: StepChange and MoneyHelper in the UK, MABS in Ireland, NFCC in the US, Credit Counselling Canada, the National Debt Helpline in Australia and MoneyTalks in New Zealand. The app links to the right one for you.

Make next payday the one where it changes.
