Type in your wages. Debt Slayer tells you exactly how much goes to bills, debts, savings and spending, so nothing catches you out before next payday.
Ten minutes to set up. Then a minute or two each payday.
How you're paid, your bills and your debts. Rent, council tax, phone, cards, loans: whatever you've got.
On payday, enter what landed. It splits it into bills, extra off debt, savings, a safety net and spending money.
Move the money, tick each one. Direct debits tick themselves. Your debts go down and your debt-free date gets closer.
Real screens from the app, with example numbers.

Exactly what to move where.

See what's paid and what's due soon.

Balances, interest and a clear-by date.

Try "what if I paid £10 more?"
Built around how people actually get paid, wherever you live.
Weekly, fortnightly, 4-weekly, twice a month or monthly, even "last working day". Your country's bank holidays handled.
Monthly, quarterly and yearly bills spread across every payday, so the big ones never hit all at once.
Snowball, avalanche, focus on one, build a buffer first, or a bit of both. Switch any time.
Adds an estimate of each month's interest, so you see how much of your payment actually comes off.
Warns you before a 0% card deal ends, so the interest doesn't sneak back.
Automatic payments mark themselves paid on the day. Tick the rest as you go.
Light, dark or Dragon mode, with a gold dragon ready to slay your debt.
Every bill and payday on one calendar, colour-coded, so you can see at a glance what lands before payday.
Clear a debt and it celebrates with you, then rolls that payment onto the next one.
Save £1 in week 1 up to £52 in week 52, and tick each one off. That's £1,378 in a year.
Reminders for payday and bills you pay yourself go straight into your phone's calendar.
UK, Ireland, US, Canada, Australia and New Zealand, with your currency and bank holidays.
No monthly fee taking money you're trying to save.
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.
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.
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.
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.
No. You pay £14.99 once. No monthly fee, no trial that turns into a charge, no paid upgrades.
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.
£14.99, charged in pounds sterling. Your bank converts it to your own currency at checkout, the same as buying from any UK shop.
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.
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.
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.
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.
