Phone plans consist of picking and choosing features that are most applicable to what you need. We can't always predict when we'd need to use SMS to send a picture or a quick message to get ahold of someone nor do we want to pay for something we might not even use. WhatsApp acts like iMessage or BBM except that it breaks through platform restrictions. Pictures and messages can be sent through your data plan and message status such as sent, delivered and read let you know that your message got through.

Maybe it's fixed now, but I gave up on Whatsapp. I found it had a habit of not displaying a "message received" icon a lot of the time on Blackberries so people constantly think you're ignoring them when in fact you haven't got any notice that they replied or messaged you (holy run on sentence batman). I found that app to be terrible...
Look at those hopeful gas prices on the gas app. I wish! ;)
Studies have shown that apps like Groupon do not save people money. In fact, they encourage people to make impulse purchases on things they don't need in neighborhoods that are far away. Then, the restrictive terms (which people frequently don't read) end up barring many people from ever using them.
Not sure if it's available Nationwide but i use Scoutmob. It has an iPhone and Android app. It works slightly different in that the deals are location based. Let's say, you're ray for lunch. You fire up Scoutmob and it tells what deals are available now in your location. You click the Use the Deal button and claim your discount. There's no buying ahead of time as there is with sites like Groupon or Amazon Local Deals, etc
Great article thanks so much and SF CHRIS I just downloaded scoutmob also!
Scoutmob is great. I've definitely used some of their nearby deals for lunch. And no need to pre-purchase anything!
@batsquatch I tend to agree that the average person does not save money, but if you exercise a little restraint and common sense you can definitely use Groupon and other similar sites to your advantage. I keep an eye out for things I know I'm going to buy anyway and pick them up. Half off at Whole Foods, Amazon, or Overstock is an easy decision for me.
Plus with the Groupon Now deals they currently offer in some cities there is less chance of forgetting about it and having your coupon go to waste.
Love Gas Buddy!
Living in the Northeast, gas prices can vary as much as 35 cents within a 15 mile area, the gas buddy app looks great. Thanks.
a lot of these apps are also available for Blackberry's too.
Thanks for this article. I just downloaded Skyscanner, and am looking forward to putting it to use! I pride myself on being a very diligent airfare shopper, but truly making a thorough search of all options can be challenging, even if you use a fare-watcher.
I agree with MichelleB, that Groupon and the like can be great ways to save money if you use them smartly. I am prone to impulse purchasing, but I have learned how to use these sites to my advantage--like buying deals that I can use for lunch near my office, house cleaning service, and spa services that I buy regularly anyway. That Whole Foods deal was awesome, by the way! Just like anything else, you can't blame the site if you fail to read the terms. But Groupon is responsive to questions about there deals and they stand behind what they offer.
Yikes! Their deals. I apologize for that typo (one of my pet peeves)!
