Know where your money’s heading, every day.
FoxxDen is a budgeting app for iPhone, made for the UK. It shows what your balance will be on any day in the months ahead, tells you how much you can safely put away, and helps you clear your credit cards in the order that saves you the most, 0% deals included.
See how it works → It takes about 15 minutes to set up, by typing a few numbers or scanning your statements, and less than 10 minutes a month to keep it right.

Made for how money works here
- A bill due on a Saturday or a bank holiday? FoxxDen moves it to the next working day, just like your bank does.
- Safe to Save tells you what you can move to savings today without dipping below the amount you like to keep in your account.
- Saving for something, or paying off a card? Set a goal and FoxxDen plans it around your pay days. On a 0% deal, it gives you a date to pay by, 10 days before the deal ends.
- Got more than one goal? Share your spare money between them, like most of it to a card and some to a holiday, because the good times matter too.
- See how close you are to a safety net of three months’ essential bills, so a surprise doesn’t end up on a credit card.
- Keep bills and spending in separate accounts if you like, and FoxxDen will let you know if your spending money isn’t stretching far enough.
- Just ask: “How much could I save by Christmas?”
