Mobile Killer App
 There is no 1 Killer App
 The mobile is a personal device and
mobile applications should reflect that

Software : the old way

Software : the old way
 Due to the steep learning curve of
traditional software development, the
person with the application idea is
unlikely to be a “coder”.
 This results in a relatively small set of
applications that tend to target large
audiences.
 High complexity leads to high prices in a
low-margin business

Mobile Software: the old way
 Not Cross-platform (except J2ME to
some extend).
 Medium to very high entry level.
 Distribution is difficult.

Introducing Glowe
Glowe defines a format for describing
applications.
Glowe applications run inside a runtime
environment (or engine) making them
platform independent.
Glowe applications describe the flow of
information.
Glowe applications are made by linking
building blocks.

Software: the Glowe way
Mobile applications are about bringing the right
information to the user and allowing
communication in a user-friendly way.
So the Glowe way of developing applications
focuses on :
 Information
 Communication
 Presentation

Software: the Glowe way
Technical details:
- Simple, open XML format
- Editable in Notepad (or vi )
- 1 application = 1 file
- A pre-defined set of building blocks
- Multi-platform ready:
- Mobile
- Web
- Embedded
- You’ll score with the ladies

Glowe Building Blocks
The Glowe way of application development
offers building blocks to “build” instead of
“code” information centric applications.
There are building blocks available for
- Retrieving information
- Reformatting information
- Combining information streams
- Pushing information back into the cloud
- Displaying information in a rich mobile
interface
- Interacting with the user
