Top Mobile Apps for Summer Travel

by Phil McGuinness

At Key Lime Interactive, we’ve provided competitive research analysis in the Auto Insurance and Banking Industry mobile app offerings for years. Now, on the heels of TripAdvisor reporting a milestone of 100 million iPhone and Android app downloads, we decided to take a quick peek at four top travel booking apps to see how they compare. We selected four brands and evaluated the Android app flight finding and booking process to find out which have the best usability, ranking them not only on number of features, but execution.

Our Methodology
The apps were awarded points or scored based on two criteria

  1. The total number of available capabilities to users
  2. The successful execution of each

In review, each app was credited for an integrated capability, such as sorting, filtering, alerts, or the ability to save flight information.   After this we looked at the execution of each feature to provide more nuance to the rankings, such as the number of sorting/filtering options provided or the flexibility of alert settings for apps that had flight alerts. The final positioning of each app in our ranking is based on a combination of those two measurements.

NUMBER 4: Expedia

Expedia is far and above the best looking app of the this group, from the landing screen that scrolls hotel and flight   destinations via colorful pictures, to the search results loading screen that mimics the view out your airplane window. The app is also extremely quick and responsive, allowing both departing and return flights to be selected without any extended load time. However, there is not much that stands out in this app beyond those features. The flight search has only a few    basic options. The results page and booking engine are relatively sparse, with only four sorting options available for results.  Although the aesthetics are exceptional, the lack of functionality in Expedia’s app results in a lower ranking in comparison  to the other apps we reviewed.

NUMBER 3: Priceline

Priceline, which acquired Kayak in June 2013, ranked just ahead of Expedia in the find flight and booking analysis. The  app has a strong branding message. William Shatner and Kaley Cuoco are available in the lower left hand corner to  chauffeur you through a flight search. During the search process, Priceline saves recent airport searches in a list, which  rewards the user for repeated uses of the app. The results page also provides six different sorting options, from Number of  Stops to Airline, which is great for users who want to avoid specific airlines or too many layovers. While the remainder of  the experience is solid, Priceline lacks to the bells and whistles of some of the apps in this competitor set.

NUMBER 2: TripAdvisor

TripAdvisor’s strengths are apparent from the minute you land on the results page, where sorting and filtering options are available. This allows users to select time of day for departure or arrival, the number of stops, or to view specific airlines. Additionally, users can request alerts for flight prices from within the app, and the bottom bar links to comparison rates from other providers making it easier for bargain hunters to find the best price. Finally, users who want to save their information for later can e-mail their itinerary after selecting flights – a very convenient feature for frequent travelers who need to keep their itinerary close at hand.


 Kayak’s no-frills interface belies a wealth of functionality, and ranks first primarily due to stronger execution of features  that  can be found in the TripAdvisor app. Kayak has the most robust sorting and filtering menus available, as well as  extensive options for setting alerts. The app is also the only one we evaluated that allowed multi-city flight searches.  Anyone thinking of hopping around Europe this summer will appreciate this feature. During the flight search, the  Kayak app allows users to add any nearby airports to their search, truly a plus when traveling to or from areas with  multiple airports that may have better fares. The quality of Kayak’s many features make it best in class for flight finding  and booking.

 We hope you found this ranking helpful. Key Lime Interactive offers expanded custom competitive research. If you’d like  more information, please contact KLI  here.

HTML5 or Native OS: Which is Right for Your Business?

by Phil McGuinness
A hot topic right now in mobile user experience is the debate between providing an HTML5 web app versus a more traditional Native OS app. Simply put, HTML5 is a method of programming a mobile website to behave like an app (think which can be accessed through any modern tablet or smartphone browser. Conversely, apps written for a Native OS are  developed to run directly on Android or iOS smartphones (they are designed for each native platform), and must be downloaded through the GooglePlay Store or Apple App Store. Both approaches are a great way to provide web content to smartphone and tablet users, and they each have their own strengths and weaknesses. Which of these approaches is right for your business? At Key Lime Interactive, we are exploring this question in depth, and have key information to help you make the right decision.
From a development standpoint, HTML5 is the clear winner in both cost and flexibility. If your business has a website, it’s a given that you already have programmers on hand who can write HTML5 code.  In addition, your programmers will only have to program the basic code once.  Of course, during QA testing some minor edits will need to be made in order to support different browsers and browser versions in the marketplace such as Chrome, Safari, Explorer and more. It’s also important to note that since your code lives on the web rather than on a user’s device, you can make changes on the fly without having to roll out a new application update via an App Store update every time you make a change.
If you decide to make a Native OS app, you will need to hire  a team  who know the specific language for each operating system, or a jack-of-all-trades programmer who knows all of the relevant languages. These programming skills are much less common, and therefore, can be more expensive, than HTML5-only developers.  In order to provide a robust and compelling experience for each OS, you’ll need someone who understands the nuances of each platform. This requires a developer who can write for each operating system, and that’s no small task. If you decide to go the path of a a Native OS app then you’re developing for both Android and iOS and that means you’re now doubling every step of the cycle, including programming, testing/QA, and maintaining the code. When it comes time to update your apps, you’ll also need to release an update two versions via the GooglePlay Store or the Apple App Store.Publishing via either store requires approval before your app can be made available for download.
So why use the Native OS app approach at all you might ask? It sounds expensive AND time consuming. We would submit that developing for a Native OS platform is the right choice.  This approach excels at something that we at KLI hold near and dear to our hearts: you guessed it, user experience! Currently, an HTML5 mobile site compete to a Native OS app in look, feel, functionality, and overall speed. Of course, Android and iOS platforms have quirks which make for a unique user experience on each device but the robust and rich UX is worth the price of admission. See our previous article for a detailed discussion about  how Android users can be alienated by seemingly insignificant design choices. When building an HTML5 web app to be standardized across all devices, you lose the custom feel ofa Native OS app.
The functionality advantage for Native OS apps comes partially from a better support system – not only from Apple and Google – but from the online community of app programmers – and also from the apps being installed directly on the device.  This allows easy access to smartphone features such as the camera, calendar, or contacts. HTML5 web apps are starting to add these functionalities as programmers begin to develop clever new approaches, but equivalency is a long way off at this point in time. Finally, it is well known throughout the industry that the HTML5 web apps react significantly slower than Native OS apps in both UI and load speed. These factors combine to create a smoother, faster, and more intuitive user experience for a Native OS app.
The other main areas differences  between these two approaches relate to  security, monetization, and accessibility, which will vary in importance can be depending on what you want from your app. Native OS apps have better security since the code and URL strings are not accessible like they are in an HTML5 web app. If you happen to want your app to be accessible online, you’ll need to stick with Native OS.  To rely on an existing app store for monetization, you’ll need to either build a Native OS app, or use a program like PhoneGap to “wrap” your HTML5 web app to make it appear as an app in the app store that users can download, although it only behaves as a link to the web app itself.  Of course, selling your app through an app store means giving away a cut of the profit to the owner of that store/ HTML5 web apps allows you to create your own monetization strategy and avoid the App Store fees.
In conclusion, it takes careful consideration of your business, and knowledge of each approach to make the right decision for you. Do you need a less expensive, low-frills, dynamic experience? If so, an HTML5 web app would be the best approach for you. However, if your major concerns are usability, performance, and security, and you have a little room in your development budget, then a  Native OS approach is the way to go.  In our opinion, until HTML5 can catch up to the user experience provided by Native OS apps, enterprise companies will almost always want to represent themselves with Native OS apps for the enhanced usability and unparaelleled user experience. In the coming months, Key Lime Interactive will be conducting a study to measure the current user experience of HTML5 web apps, so stay tuned for more detailed information in a future newsletter.
