The local web is suitable for obtaining more information from various databases, and by searching, you can easily reach all your desired items. There are many software and applications that you must use to install them on your mobile phone or desktop system. These soft wares and applications may be very large. To solve this problem and ease of work, web applications are designed that do not require installation to use software or applications and can be accessed and used through the web.
What is a web application?
Web applications are actually software services that are provided to users on the web. In the past, to perform daily tasks, it was necessary to install software on the desktop system or application on the mobile operating system, but today, with the emergence of web applications, there is no need to install applications with a larger volume, and only through Web and enter the URL can be accessed and used by the application. Websites may have been used in the past as resources for accessing content, but today, with the combination of websites and applications, the functionality of websites has also changed and increased. Web apps work just like any other app, and they have an attractive user interface just like any other app. Web applications also have the ability to be responsive and are accessible through both smart devices and desktop systems. The name of advanced web applications means that we add features or capabilities to the program step by step, or step by step, without the need for higher versions to support devices or hardware and software resources. Have more days.
How to access and use web applications
As the name implies, access to this type of application is possible through websites. In this way, by entering their address and URL in the search engine search bar, they can be easily accessed. After first entering the web applications via the web, you will see a message titled Add shortcuts to the desktop screen or add shortcuts to the mobile page Add to home screen. And you can easily access it later by adding its shortcuts on your desktop screen. The difference between web application shortcuts and software installation is that the volume of installation programs is very large, but web application shortcuts have no volume and can be easily added and removed.
Features and Benefits of Using Progressive Web Apps
High execution speed:
Due to the fact that they do not require any hardware or software to install and are installed on virtual Internet hosts and servers, it has a very high speed in setting up and running. Such applications are installed on virtual hosts and servers and are not installed on any device or hardware, which is why the speed of processing and launching it is higher than other programs. Users can access such web applications easily and quickly by having a system and the Internet, and also because such applications do not need to be downloaded and installed, they are faster to launch and run.
Regular service to users:
This type of applications that are installed on virtual hosts and servers by sending notifications and stored in the user's device, always engage them and can monitor the user's activity live and Always keep active and provide services to them.
Ability to run on any platform and operating system:
These applications are located on the web platform and virtual server that can be launched in any operating system and using any browser and search engine. In other words, this type of application is compatible with all operating systems, with all browsers and can be run and launched by any of them.
Such applications, like other native applications, do not have a difficult and complex installation process and can be used easily. This feature is one of the advantages of web applications that users have noticed, because it does not need to go to the App Store or Google Play
Low development costs:
Web applications have all the features that other native applications provide to users, and users can use similar features non-installed through the web. Therefore, the amount of effort that developers make is reduced, and on the other hand, it does not require any hardware or software resources to set up, so the costs must be reduced.
Standard user interface:
The standard user interface is responsive, which can be accessed by all smart devices and through the web and by searching in various search engines and browsers. Also, such web applications are compatible with the size of all mobile screens and desktop screens and are shown to fit the size of all screens. The space and environment of these applications is exactly the same as the space and environment of software and installation applications, with the difference that it no longer needs to be installed.
Some users may doubt the security of these applications, but it should be noted that such applications are all SSL-licensed and create a completely secure environment for users.
The information entered by users and access to these applications is completely secure.
Ability to run offline:
One of the obvious differences between web applications and other applications is that it is possible to access web applications offline. Web applications can be made available to users offline and data can be easily exchanged after connecting to the Internet. However, considering that some web applications, unlike installation applications, require an Internet connection, access to such web applications offline should be avoided. Like Instagram , which has an Internet version of its application to access the Internet, so access to the web version of the application will not be possible without an Internet connection.
Other features of web applications:
In using other native applications, if a link is placed, users will have access to that page after a while after clicking on it. But in web applications, due to the integration of their environment, both of which are on the web, access to linked pages will be done very quickly. In using web applications, there is the possibility of bookmarking them, simple sharing of web applications through links, and the possibility of searching and quick access through search engines, and are other features of web applications.
PWA compared to native Android, iOS and Windows applications
Due to the fact that native applications are designed for each platform and version of the operating system with other programming languages, it is not possible to run them on any operating system or on any platform, and you must find the appropriate
with the platform and operating system. Which is time consuming and even costly. But the use of web applications has made it possible for all users to access the program they need with any operating system, with any platform and with any device and hardware.
Or users may want to update the app they are using and benefit from newer versions, but are unable to do so due to software and hardware limitations on their device. For example, it may not be possible to upgrade to more up-to-date versions due to the low version of the hardware source. Or due to differences in software resources and operating systems, it is possible to install and upgrade. With web applications, it is possible for all users to always use the latest versions of applications or not to be deprived of using these applications due to the low level and version of hardware and software resources. In other words, all users have access to a single source, and if an update is made, all users can use the updated applications.
The three main axes of web applications:
- Ability to install
Advantages of using local applications over web applications:
Ability to have full access to hardware resources and other features of the phone:
In using local applications, users can use all the features of the phone such as notifications, GPS, camera and other hardware features. Also, each of the local programs has its own specific icon that allows easy and fast access after installation.
Much more time share of user interaction during the day:
According to statistics, users spend about 90% of their time on native and existing applications on their devices and only 10% of their time to use web applications or web browsing.
Disadvantages of using local applications compared to web applications
Users do not want to install applications:
Due to the bulk and weight of many applications, users are not interested in installing applications on their systems, so they avoid installing a large number of applications and prefer web applications with Use more up-to-date versions.
Existence of various operating systems:
There are various operating systems with various platforms, each of which must be designed separately in system versions and mobile versions, which is a problem that most users face and to use. Local applications must provide a version related to their operating system, which the existence of web
has solved all these problems.
Web applications are highly developed and have been welcomed and used by many users because they do not need to be installed on hardware and software resources, they can be provided offline. It is recommended to use web applications in case of volume problems and lack of hardware and software resources.
