You may recall I did a series over the summer called the 30 Days of Money-Saving Apps. I got such a positive response that I wanted to add one more called CoupSmart (when you “like” CoupSmart on Facebook through 12/12 $1 goes to help fight pediatric cancer for every new fan).

The free CoupSmart iPhone app lets you scan products you buy every week. You’re basically letting CoupSmart know what you like to buy, then they send you coupons by mail for products you buy and use. They also mail out trial offers and free samples based on your scans. I just got a coupon by mail last week for a free bottle of Fit Fruit & Vegetable Wash (not free with purchase, but free).

Plus, every week CoupSmart is giving out daily and weekly prizes to top scanners. The app is available for iPhone now, but will soon be available for Android and Blackberry users too. Worried about product recalls? You can even sign up for CoupSmart Defender to get notices by email (no smartphone required).

Even better, CoupSmart is giving back by way of a new program called GiveSmart. Every month, the charity with the most points receives a $1000 donation. Be sure to check out all the posts in my 30 Days of Money-Saving Apps series.

Who needs a pricey GPS device when you can get directions and turn-by-turn voice navigation on your iPhone? This is where the free MapQuest 4 Mobile app for the iPhone or iPod Touch comes in.

While I’ve used the free Google Maps app that comes pre-installed on the iPhone, I haven’t been able to use it when I need it – when I’m driving. So I love that the free MapQuest 4 Mobile app speaks to me to give me directions and even re-routes automatically if I get turned around, which is a great time saver too.

One cool money-saving feature is that you can set the app to automatically avoid toll roads. If a location is a short distance away you can also set the app to alert you to walking directions. The app can help you find local gas stations too (don’t forget that the free Cheap Gas! app can help you find the cheapest gas).

It’s summertime and it’s time to hit the shore with the kids. If your plans involve sharing a beach rental with another family, then the free Share-A-Bill app (the lite version) may be for you.

It’s never easy to figure out how much each family owes when one person buys groceries and another pays for the rental or an evening out. With this app, you just key in expenses and who paid for each one (up to four with the free version). Then the free Share-A-Bill app does the work for you, sorting out how much each person owes and to whom.

This would be a nice app to use when going out with friends for a night on the town. It never fails that I always feel like I’ve paid too little or too much at the end of an evening. I like that this app will tell me exactly what I owe. Plus, don’t forget about the free Tip’n’Go app when dining out with several people as well.

I know that among the money-saving blog readers there are a lot of Dave Ramsey fans, so I was excited to find the free Ask Dave Ramsey app for the iPhone and iPod Touch.

You can peruse the most recent call-in topics. The app lets you both read a short summary of a listener’s question and Dave’s answer, as well as listen to the on-air exchange. You can also browse for advice from Dave by category, including The Basics (automobile, taxes, etc.), Handling Money, Lifestyles (career, college, etc.), Long Term and Fun Stuff.

Choose the Random button and you’ll see a listing of 10 or so topics that range from how to start an LLC to teaching kids about money at an early age. You can also search the free Ask Dave Ramsey app if you have a specific money-saving topic in mind for which you’d like Dave’s sage advice.

If you’ve ever been in a situation where you’ve needed to figure out whether it’s cheaper to buy 24 cans of Pepsi or 30 cans of Coke, then the free app, The Better Buy, is for you.

Here’s how it works. If you have the prices for two comparable items, just enter the price and the quantity (e.g., 24 cans, 12 rolls, 14.5 oz, etc.) for the first item, then the same for the second item. In a flash, The Better Buy will tell you which is the better deal.

I especially like this app because many times I’ll be at the grocery store planning to buy the larger bottle of ketchup or dishwasher detergent but then will notice that the smaller bottle is marked down. No longer will I need to try to figure out the math in my head, The Better Buy will be able to tell me on the spot which one I should purchase.

I stumbled upon the free RepairPal app the other day and wished I’d found it sooner considering my car has needed repairs several times in the last few months.

Here’s how it works. First, select the make, model and year of your car. Next, select the type of service you require, whether it’s scheduled maintenance (e.g., 30,000 mile service) or a replacement (e.g., new transmission, new fuel pump, etc.). You’ll also find various services listed like tire rotation and a check engine light diagnosis. Finally, enter your zip code and press the big orange “Get Estimate” button.

Once you enter your details, the RepairPal app will give you a price estimate broken out between parts and labor, which is nice. The app even finds repair shops close to your location and will email the price estimate to you to save for later. I can definitely see good use for this as a negotiating tool once at the repair shop and I’ve been given an estimate at the desk.

I can’t say I can’t wait to try out this app in a real scenario (it’s not like I want to be in a position to need car repairs done), but I know the RepairPal app will be a huge help. Be sure to check out all the posts in my 30 Days of Money-Saving Apps series.
