Last year, I wrote about my favorite iPhone apps for traveling . Now, I have some more. I LOVE these apps. They made my recent travels so much easier.

1. Tripit. Free. This is a great app. As I plan my vacations, I email all the reservations to plans@tripit.com (after signing up), and it puts together my itinerary in one folder. You don’t have to be online to access the information, and Tripit adds helpful items such as maps, directions and weather info. Really handy.

2. TripAdvisor . Free. I’ve used this for years on my desktop, but the iPhone app is wonderful when you’re on the go. When we were recently in Europe, we’d see a restaurant that looked good, and I would go on TripAdvisor to see what sort of ratings it got from other travelers. That helped us avoid some places that got really bad reviews. It also has a “near me now” feature that will show nearby attractions, restaurants and hotels – and their ratings.

3. FlightTrack . $4.99. This is a bit pricey for an app, but it’s worth it. You simply enter your flight information, and you get all the real-time information about your flight – delays, gates number, etc. It also has a map so you can track flights. This app works internationally.

4. iTranslate . Free. For international travel, this app is a must-have. It translates words and phrases in more than 50 languages. It also has free audio in 18 languages, so you can hear how the word is supposed to sound.

5. Words With Friends . Free/$1.99. I’m cheating a bit here. Obviously, Words With Friends isn’t strictly for travel. But this Scrabble-like iPhone game sure comes in handy when you’re sitting in an airport waiting for a flight or just have some downtime in your hotel room. And I’d like to think it’s a bit more stimulating than, say, Angry Birds. The free version has pop-up ads; it was worth it to me to spring for the $1.99 ad-free version.

As an app reviewer, I spend an inordinate amount of time browsing apps and app reviews in Apple’s App Store. When I’m considering an app review, or considering purchasing an app for personal use, one of the first things that I do is to read the user reviews, as I’m sure many of you do too.

Unfortunately, a newly released app or an app without a lot of reviews can sometimes have fake reviews, planted by developers or their friends, to trick unsuspecting customers and artificially inflate ratings. We’ve developed a quick guide that will help you avoid apps that are being falsely promoted.

Recently, at PadGadget, we came across a few apps with not just one or two fake reviews, but 30 or 40. One of the apps even had upwards of a hundred fake reviews, which was baffling to me because it takes a lot of effort to make that many false iTunes accounts.

Fake reviews are a problem that has plagued the App Store since its inception, and while Apple has made an effort to curtail falsifying ratings, no system is flawless, and it’s still an issue that users need to be well aware of when buying an untested app.

Back in May, Apple changed its app review policies, disallowing reviews of apps received from promo codes. Previously, App Store developers could request multiple promo codes to send to friends, who could then falsified reviews for the app. While promo codes can’t be used to for reviews anymore, developers can still use gifted apps and fake iTunes accounts to purchase apps and leave positive reviews, so it’s important to be vigilant when choosing an app.

Here are some obvious signs that a review is fake:

The titles are all similar. Every user has to enter a title for a review, and when an individual is creating multiple titles in quick succession, they tend to be similar. Look out for reviews that all start with one word titles, or have a lot of the same words, like “great app,” awesome app,” “good app.” Here’s some titles of actual fake reviews: “amazing,” “nice,” “good,” “awesome.”

Similarities in punctuation. We all have particular writing styles and tendencies towards certain words and punctuation. A person who regularly uses two exclamation points instead of one will often do that in multiple reviews, and the same is true of capitalization, comma usage, ellipses, and other punctuation marks. Additionally, if a word is misspelled in one review, it will often be misspelled in all of them. Two of the fake reviews, posted one right after another: “cool graphics.. loving it” and “its great fun addicting..” The two single periods in each review are a dead giveaway that these aren’t real reviews.

Names. The person writing fake reviews needs to come up with several different iTunes accounts in one sitting, and our brains aren’t wired to pick up on our own nuances. Several two word names, like Bob Smith, Brian Jensen, Pete Jones, and Frank Johnson are incongruous. Real people have widely varied user names.

Problems with syntax. Like with punctuation and spelling, different reviews that truly come from just one user will share similarities in syntax: “it’s a cool game but it’s hard. if you like a challenge get this game”; “great game and fun. pretty difficult to get high scores.”; its hard at first. once you get the hang of it, its fun!” All of these reviews are short sentences, with with similar content and style.

Clicking on a user’s name who left a review will take you to a list of all the reviews they’ve written. If there’s only a few, and they consistently give high reviews, be suspicious. Often, these users will leave reviews for the same group of apps, so click a few and find out if they have all been commenting on the same apps. As a bonus, you’ll find other apps to avoid! The catch is that this technique only works when you’re on your computer, so whenever possible, resist that impulse purchase on your iPhone or iPad and check it out first.

In the apps that I mentioned, with reviews by a developer that was padding their own ratings, there are hundreds of positive comments and then approximately ten negative, angry comments from customers who were falsely tricked into purchasing the app, and then realized the reviews were fake after the fact.

While there are some true independent gems in the App Store, a good rule of thumb is to also check out the other apps that a developer has put out. In the case that I mentioned, they have several apps all with fake reviews by the same group of iTunes accounts, so it was very obvious.

If you take a look at all the reviews and see clear links between them, it’s best to avoid the app and losing money. Google can be helpful as well. There are a lot of app reviewing sites out there, including PadGadget, who work hard to bring you honest information and opinions about apps. If there aren’t any third party reviews, and the app looks suspicious, trust your intuition and save yourself the frustration of downloading an app that’s been falsely promoted.

1. Business Case: If you have an idea that could make in to a good mobile application, you should first research if another application on same / similar idea already exist. Determine how you can differentiate and improvise your idea. Understand if there is a need for the application that you plan to develop. Besides validating your concept, assess if developing that application is a good fit for your business strategies, direction, and if you will be able to recoup investment in to developing this application.

2. Target Audience: Whether you are developing application for your internal business use, use by other businesses, or use by individual consumers, you should have a good understanding of who your target audience is. That will help making design and technology decisions for your application. If you are targeting global audience, you may also have to consider making your mobile application multi-lingual.

3. Technology Selection: With mobile client applications, you cannot develop a single application that can run on all of the mobile platforms. Each of the mobile platforms is different and run only applications that are developed on the specific technologies. So if you develop an iPhone application, you cannot run the same application on Android, Blackberry, or Windows Mobile platforms. That is why it is important that before beginning application development, you select an appropriate mobile platform for your application. If your plan includes developing application for multiple mobile platforms, make sure that you architect your application properly to reduce initial and ongoing development efforts and costs. Most importantly, determine if you really need to develop a mobile client applications which are platform specific or a mobile website / web application which are more universal and could run on all smart phones.

4. Timing: When there are thousands of businesses trying to tap in to the booming mobile applications market, it is critical that you move forward with your mobile development project in a timely manner. Otherwise, there are chances that someone else may beat you in launching an application with similar concept and could quickly tap in to your potential client base. When it comes to launching a mobile application, right timing is essential for maximizing return on investment.

5. Pricing: Just like any other product, you need to make sure that price for your mobile application is right. Research on the price of other similar apps, determine how valuable is your application going to be for consumers, and figure out your total cost of ownership for building, launching, and maintaining your application. Consider offering your mobile applications for free or at a discounted price for a short period of time to attract more buyers.

Bonus Point: Marketing – After launching your application, it is important to market it and improve its visibility to your target audience. Without the marketing efforts, your application may get buried under the stack of thousands of other applications hurting its revenue potential. Marketing your application on social media sites, search engines, and offering it for free for a short period of time should help increase its consumer base. Make sure to listen to the feedback application users will be giving and incorporate that in to your future development plan.

But, whilst its new Android app is similar to its existing iPhone edition in many functional respects, there is one critical difference…

Though the latter remains accessible only via six- or 12-month paid subscription in the UK, the Android app is being launched for free with advertising subsidy .

That means The Guardian believes it can charge high-end British iPhone users but not mass-market Android owners (or overseas iPhone users, who are also not subject to the fees). It constitutes another supposition, by a big-league content proprietor, that the Android segment is not one ripe for charging through .

“We feel that having a free, ad-funded Android app is the right business model for this marketplace and platform at this point in time,” a Guardian News Media spokesperson tells paidContent. “We have no plans to change our iPhone pricing model as it stands, though we are always reviewing and watching the market very closely.”

The Guardian allows developers to re-publish its content for free through its API (though the process of monetising that content has barely begun), and several Android apps already offer Guardian articles for free.

The split mobile business model is more than just a bifurcated app strategy. In promotion, The Guardian also promotes its free mobile website harder than its subscription iPhone mobile app. This summer, the mobile website comprised a tenth of Guardian.co.uk’s total traffic.

This all bucks the received wisdom of many, that mobile apps can charge for content because, unlike the desktop web, mobiles have little prior culture free consumption.

The message is clear – if you want free Guardian, use the desktop or mobile website or Android; if you want to pay what is the equivalent of four daily print copies for an entire year’s mobile app access, use the iPhone app.

In a fit of ad targeting, the new app’s sponsorship across the board is for Samsung’s Galaxy Tab, an Android tablet. Samsung is going ahead and selling the 10.1 device in the UK from today after a European injunction against it was temporarily suspended.

After revising its iPhone app on a subscription model in January, by June, 67,258 people had subscribed to the app (in the UK, 72 percent of them for one year at 3.99, 28 percent for six months at 2.99). That suggests it made 193,218 from annual subs and 56,308 from six-month subs in the first half of the year, for a total 249,526 before Apple’s commission.

The milestone coincided with the first of the six-month subscribers being required to renew. But The Guardian won’t disclose how many people have done so.

It also coincided with Apple’s new policy of requiring subscription payments go through iTunes Store with 30 percent commission. “Our iPhone subscriptions have always run through iTunes, so there is no change in terms of the 30 percent issue,” a spokesperson says.

The iPhone app has been downloaded 52,915 times in the States, where it is free because The Guardian wants to build an audience there.

Minimum hardware requirement for iPhone apps development is to have an Intel-based Mac running Leopard (OS X 10.5.3 or later). Any Mac released since 2006, laptop or desktop, should work. Though it is not required, but if you have a solid background of Cocoa development – Apple’s Objective-C framework with the xCode development on the Mac platform, developing iPhone Apps should be a seamless and beautiful experience. When one sets out to become iPhone app developer , following are some hurdles that one has to face:

(1) How to use the Mac and Leopard: If you are a die-hard Windows user, and you are all set to become an iPhone app developer, you need to learn how to operate Mac/Leopard OS X world. If you are not well-versed with this operating system, developing iPhone apps can be quite a frustrating experience.

(2) How to download and install the iPhone App SDK: For a beginner, to download Apple’s software development kit is a bit difficult as .dmg files which are disk images explanation are not that usual. They can be downloaded with the help of Mac 101.

(4) Need to Do Crash Course in OOP, Objective C and Cocoa: Any beginner needs to spend much of his/her time learning the basics of object oriented programming and Objective-C, and Apple’s proprietary Cocoa. It also is important to learn how to implement the language in the real application development. Having mastered this language makes a lot of difference in creating ravishing iPhone applications.

(5) Taking eternal helps in the form of books and other sources: Before 2008, when Apple lifted its NDA restrictions, every iPhone apps developer was a world unto him. There was practically nothing to learn and to share about his/her views regarding iPhone apps development. Now, there are myriads of books, on line forums, blogs and other stuff coming up to provide the developers a platform to share their views regarding the development and learn from them as well.

(6) Deciphering Cocoa tutorials and other learning material: Almost all tutorials expect iPhone apps developers to be well versed with Cocoa, xCode and Interface Builder. Now, if you directly access various iPhone templates, sample code and tutorials, that is going to be very confusing. Therefore, you can just use them to lean how to build a Mac App using the software development kit tools before taking iPhone apps test. Normally, the tutorial has model, view and controller design structure that makes the iPhone apps developer absolutely in control.

Hence, any iPhone apps developer need to have some basic background of both hardware and software in order to carry out iPhone apps development.

You’re probably thinking “What? Under-5 iPhone users?” Well, that’s exactly how I felt until the first time I handed my brand new iPhone 3G over to my 4-year-old twins. I needed just 15 minutes of quiet after I made mistake of bringing them along to an important meeting. I quickly went to the App Store and found an application for preschoolers for 99 cents, and right then and there, they were addicted – and my iPhone wasn’t really mine anymore.

Apple likes to target the younger buyer in their advertising, but they probably never had the under-five set in mind as potential iPhone users. Well, neither did I when I shelled out $200 for my new phone, not to mention the even pricier AT&T contract. My phone has now become their favorite toy and I have to wait my turn if I want to use it. They know how to flip to the screen with their favorite apps and are nice enough to answer all my incoming calls that interrupt their games – and promptly hang up so they can get back to playing.

I can’t be the only one out there with a hijacked iPhone, so if this sounds familiar to you, take a look at a few of my kids’ favorite apps, all of them parent-approved for appropriate content and educational value – and also a bargain at only 99 cents each.

1) Our first kid app remains our favorite: Preschool Adventure by 3DAL. The best thing about it is it caters to short attention spans by offering six different games, all of them educational. Kids can learn colors, numbers, shapes and body parts, as well as do a silly little matching game and touch animals on a barnyard background to hear their sounds. The kids are getting a little old for this one, so it’s probably better for the 3 and under group.

2) Wheels on the Bus by Duck Duck Moose Design is their new favorite and your kids will find this riff on the old classic “Wheels on the Bus” both entertaining and good for a sing-along. They can tap and slide their way through different scenes on a bus as doors open and shut; wipers swish and passengers bounce up and down. Parents will probably be amused by trying out the different language and music options. Did you know wipers go “Shwee shwee shwee” in France?

3) Also by 3DAL is another of our favorites, Preschool Music. It has the same colorful and simple graphics as Preschool Adventure but focuses on music. You’ll find a simple keyboard where kids can compose a tune that’s then recited by a cheerful parrot, an undersea percussion and rhythm game, and a silly group of parrots that sing in a round. They’ll be as fascinated as you are irritated by the repetition of musical sounds.

4) If you’ve got a Pre-K kid who needs to learn sight words, you’ll find an app just for that with SightWords. It’s pretty basic, but you’ll find 300+ high frequency “flash cards” and your child can move from levels 1 to 5 as they master one set of words. They can touch the screen to hear the word pronounced if they’re stumped, and move back and forth from word to word with arrows at the bottom of the screen.

5) To finish it off, everyone’s least favorite: Math. Well, not really. My kids think it’s great, and are starting to understand basic math concepts thanks to Math Magic. It gently prompts kids towards the right answers with encouraging “You can do it-s” when they get an answer wrong, plus with lots of flashy stars and other animation, they’ll feel like they’re playing a game instead of learning simple addition and subtraction.

I would be lying if I said that these are my kids’ favorite apps. My son’s addicted to Days of Thunder (even though he crashes more than goes), and my daughter is a pro at Tap Tap Revenge. But as a parent who’s more concerned with education than mindless entertainment, these are my top picks.

Now that you know where to start when it comes to finding some great preschool apps, be prepared to say “bye-bye” to your phone! Now if only they made truly indestructible iPhone cases for kids . . . I haven’t found one yet, so I’m considering buying them an iPod Touch for their next birthday!
