• A native app is specifically designed to run on a device’s operating system and machine firmware, and typically needs to be adapted for different devices. A Web app, or browser application, is one in which all or some parts of the software are downloaded from the Web each time it is run. It can usually be accessed from all Web-capable phones.
•  Having a web app means that you can customize and re-style your app’s design at any time – no compiling, app store resubmissions, user updates, or technical process required.  And all this is included in your monthly subscription fee.
•  A web app reduces your time to market.  We can often have your app ready to deploy with hours, not weeks.
•  Your OneTouch App will work across all popular touch smartphones and tablets.  There is no need to create a different app for every device.
• There is a misconception that Web apps cannot offer access to device capabilities, but the W3C is leading a concerted effort among browser vendors, handset manufacturers and operators to introduce such features via browser application programming interface (API)s.
•  In fact the GPS API is already publicly available and included in many new browsers/handsets. We would not be surprised if in 1-2 years we will have augmented reality (AR) Web apps that will use the handset’s camera, accelerometer and GPS.
