Why we are the best mobile apps developers in Nepal?


Every product owner wants to develop a mobile app but no one wants to get lost after launching an app. There are some qualities that is essential to make a mobile app successful. We will discuss the key-features that makes mobile app not only look awesome but also simple, secure and user-friendly.



How to develop a good mobile app?

The answer is really simple. The most important thing is simplicity. Though it has very few screens and does only one task, it should look as simple as possible. Mobile App should follow standard guidelines from Apple for iOS and from Google for Android. Following are some features one should follow to make better mobile apps.


1. Simple User Interface (UI)

The app’s user interface should have simple flow proposed by the respective platform. It should have proper navigation flow, button’s height & width in the app should be enough for a user to tap. User should go back and forth from one screen to another easily. It should follow typography guidelines. One thing we should not forget that the default is always good. So it is always good to use system default fonts for texts and headings. We can use custom fonts if we are developing games. Games are those apps where user wants to see fancy stuffs.


2. High Performance and Responsive

Lots of developers and clients give their full effort to make fancy app, but if it is not performing well it will be useless. Mobile app user cannot wait more than few seconds to perform some actions. We should focus to reduce response time whenever user does some action. If app is taking too much time in the very first run, user will uninstall it in no time.


3. Compatibility with different OS versions and devices

Compatibility is the major part of app development. If you want to cover large audience or clients, you have to make app compatible with various devices and OS (Operating System) versions. Apart from iOS, Android has variety of devices and OS versions. There are many Android phone manufactures which do not only ship devices with different OS versions but also with custom ROMs (modified Android OS). You need to think wisely before you think to make it compatible with different versions, It might increase development time and so the cost.


4. Privacy

Users’ privacy matters. A user does not want to give her email address or health data unless it is really required. We should not ask user for their location data (GPS) unless our app gives some location based services. It is always good idea to give user to opt out sign up process. We can ask user to login only when it is really required.


5. Security

Data security is the vital thing in the software development. App should never store user’s password and other sensitive data in the device. If required it should store data securely using popular encryption technique. Data transfer from app to backend server should be secure using SSL.


6. Work Offline

Offline support for an app is another great feature. It is required especially when we are building an app to those consumers who are movable or live/work in remote area where wifi is hardy available and/or cell data might not available.


7. Low Battery consumption

Offline support for an app is another great feature. It is required especially when we are building an app to those consumers who are movable or live/work in remote area where wifi is hardy available and/or cell data might not available.
