Mobile App Development

“Mobile applications” are used so widely yet we have never given a thought to what goes in to the minds of the makers when they give us such wonderful apps. Well to begin with, there are many; but narrowing down the number to ten we can better understand the intricacies in depth.

  1. Using cookies smartly: Cookies are used for storing a token representing user identity in order to enable automatic sign-in. But if excessive amounts of data is sent to the server for every sign in request, it negatively impacts the performance. Hence it is to be used carefully.
  2. Securing execution of data: The Mobile Web applications ensures that the user is well informed if the application needs to access personal or device information. More over users must have control around such data collection, storage, or transfer of personal information where ever it is feasible.
  3. Conservation of Resources policy: Minimum use of device memory, processor power, and network bandwidth ought to be ensured. This is be done by compression of data where ever possible, reducing delay due to redirects, larger requests are favoured over a larger number of smaller requests.
  4. Providing the best user experience: Having a good initial start-up time is what every user longs for along with a comfortable interaction method which can be Focus Based, Pointer Based or Touch Based.
  5. Variation in the delivery context: Web applications should adapt to known or discoverable properties of the Delivery Context by adjusting the content, navigation or page flow, with a view to offer a good user experience on as broad a range of devices as possible.
  6. Proper network utilisation: When an application opens fewer TCP connections and keeps them open for a longer period, it causes less network traffic, uses less time establishing new connections, and allows the TCP protocol to work more efficiently.
  7. Simplification of the Content Adaptation: The target devices need to be identified for the application and then the assignment of device classes of varying capability ought to be done. Focus has to be maintained on the application variants that would work in each class instead of building any device-specific exceptions for every variation in the device configuration.
  8. Choice of interface: If there are multiple versions of an application. Then the user must be given an opportunity to change the selection. In fact the user’s preference must be remembered for future visits in a cookie or local data store.
  9. Perfect user state: The application should not leave any services running when it is in the background. And when it is is resumed from the background, it should return the user to the exact state in which it was last used, unless the state has been invalidated by the passage of time.
  10. Security: Data retention policies and security measures to be implemented. Understanding the security risks associated with the app is of prime importance for any app developer. It ensures user data is properly safeguarded.
