A recent NY Times ad highlighted 16 different iPhone apps that can help save money, including 9 that are free. Highlights:

RN Dining – “As a member of the Rewards Network, you can save up to 15% at select restaurants. RN Dining is the easy, convenient way to find participating restaurants in your area.”

Mint.com – “Manage your bank accounts, monthly bill payments and other finances. With its constantly updated information, it’s an easy way to keep a close eye on your budget.”

RepairPal – “Locate reliable mechanics and get estimates for your vehicle repairs. And if you need roadside assistance, one tap of your iPhone will connect you to a helpline.”

All Recipes.com – “Want to dine in more? Put thousands of money-saving recipes in the palm of your hand. You can also view instructional photos, read user reviews and share your favorite dishes.”

And one I plan to download very soon:

Small Spend – “With handy charts and graphs, this app makes it easy to see exactly where your money’s going so you can make adjustments in your spending habits – and start saving money.”
