Should Libraries Create Native or Web Apps?

I have been having an increasing number of conversations with colleagues about the creation of mobile apps. Much of the conversation is not about IF apps are needed, but instead they are focused on how apps should be developed.

There are two different types of mobile apps with each technique having advantages and disadvantages.

The apps one would find in the iTunes App Store or the Android Marketplace are known as "native" apps. Native apps are pieces of software that must be installed on the device and in most cases are downloaded from a distribution point. A Web app, on the other hand, is not a piece of software but a web site optimized for viewing on mobile devices. A well designed Web app can have all the look and feel of a native app.

Develop a Native App if:
  • your library needs to take advantages of all the features built into the device itself. For example, to vibrate the phone or use GPS. However, this will be changing soon as HTML5 rolls out. Web application developers are already using solutions like PhoneGap, an open source framework suite that provides support for a variety of device features on a variety of platforms. (video)
  • your library needs to make sure content or service is available offline. If the core purpose of your application is to make your content available without an Internet connection, then a native app is needed.
  • performance and user responsiveness is crucial
  • your library is looking to try to make money directly from the sale of the app
  • your application needs to access the device file system

Develop a Web app if:

  • your library web site has all the same content that will be featured in the app
  • your library is interested in potentially reaching users on different devices and platforms with the same app. An Apple native app can only be used on iDevices and is not easily ported to other platforms such as Android and BlackBerry. Web apps are platform-agnostic.
  • your library wants its app content to appear in search engine results. Library users are begin to demand that library mobile content shows up in those results optimized for mobile devices. Content is a native app will not show up in Internet search results.

General considerations:

  • Native app development cold be more expensive than building web apps since a greater skill set is required to build apps for multiple platforms.
  • Native apps requires the use a software development kit supplied by each operating system creator.
  • Developing apps for multiple platforms would require a maintaining and creating enhancements for each.
  • Native app user interfaces tend to be smoother and takes greater advantage of the full graphics capabilities of a device.
  • Web apps require round trips to the server where the app is hosted whereas with a native app that time is almost instantaneous.
  • Web app content us more current because it refreshes itself from the network.
  • Most native app stores require approval. Web apps can be deployed immediately.
  • Native apps require updates to be installed. Web app changes are immediate.
  • Native apps may be more secure.

Technology in Use at 2011 North American International Auto Show

My buddy Jeff and I took our annual trip up to Detroit to check out the North American International Auto Show this past Monday. While we were there to see all the new automobile technology, I again paid attention to use of technology on the floor:

  • The Microsoft Kinect 3D controller was being used by both Chevrolet and Ford. Chevy had five booths with a side-by-side racing game to promote the Volt while Ford used it to capture images of attendees passing by a kiosk and then green screen the image over various backgrounds and displayed it. While many manufacturers had touch screen displays for product information, Fiat used Kinect to create an interactive display that was shown on a large display screen for everyone to see (ala Minority Report)

  • Chevrolet had a Camero flanked by cameras that produced 3D images.

  • Toyota had a touch-screen wall with three large video panels that allowed one to explore the Prius. Ford had a touch screen wall that allowed one to create custom paint jobs for the Mustang.

  • Technology/social media seen at past shows such as foursquare and Facebook were still in use. picked on the fact that I had checked in and sent me an @mention to flash their tweet at their booth for a prize. (I didn't catch the tweet)

  • Just two years ago only Kia was using QR codes. This year there were many. I wan't the only one snapping images of codes this year.

  • Flickr continues to be the image service of choice with over 3,500 photo uploads
