- Here is where you visualize worst-case scenarios that might need to operate in such an intermittent network,
- Envisage the future of the app in the marketplace
- Then, design and examine a prototype before beginning with development.
Finally, this is how you go about developing the app for real.
- Database Framework or cloud media storages would build the foundation to raise the app on.
- Application server for real time messaging and calling, such as XMPP (Extensible Messaging and Presence Protocol) or MQTT (Message Queue Telemetry Transport)
- Then, you would need a Rest API to communicate data to and from the app.

You must design the appearance of the app very carefully and creatively. Undeniably, the ‘look and feel’ do the hard-hitting piece of work and keep the users engaged with your app while enticing them to return to the app again. While designing you must focus on sentimental usage aspects, such as:

- Easy navigation. Not to be forgotten that you must handle navigation deftly both at front and back end. Distribute the features and buttons on app screen such that everything comes handy to users. Try to understand whether your customers would want a single window navigation, stacked navigation bar, search driven or gesture based navigation. Take extra care of those most frequently used features. The user friendliness is a trump card that can make your app a hit or a miss.
When you have a decently working version of the app ready, begin testing. Alpha testing, beta testing, keep on testing. It is very crucial. Run all the possible test case scenarios to ensure that you have built an all-weather robust app.
