There are all kinds of bands to track your steps, your sleep, your calories.
But now there's a new kind of wristband to track your financial fitness.
TV finance expert Nicole Lapin created a smartwatch called Cash and it keeps tabs on your budget.
You type in how much you spend and what you spend it on, and it lets you know if you're overspending.
The red line represents what you spent so far and the green represents your total budget.
Cash costs $140 and comes with three different straps.
There's also a free budgeting software available.
