"Web application development services," as an industry, is maturing. We're now at a point where the technologies we use for Web app development are changing and adapting to the needs of end-users using our apps. 

Introduction: 

Web applications are now indispensable, and the need for more streamlined workflow and faster load times is more significant than ever. This is where New Relic's Web Application Monitoring comes in. The custom web application development services dashboard provides a live view of the application's performance, reports on current trends, and detects problem areas that need immediate attention. 

This makes it easy for engineers to keep tabs on how their apps perform in real-time and where there are gaps in performance between their testing regimen and the reality of their application. 

The List of Latest trends and technologies in Web app development

Below are some of the technologies that have been introduced:

1. Blockchain Technology:

Blockchain in new applications is gaining momentum to lower the costs of distributed applications, remove the need for traditional intermediaries, and offer more secure authentication. Blockchain is a distributed database. Each block contains data but can edit only the previous block or chain. This makes it virtually impossible to change data stored in previous blocks, making it a highly secure method for storing and transferring data across large networks.

Benefits of Blockchain Technology in Web App development:

• It maintains data integrity between multiple parties.

• It makes automatic, real-time audits and verifications feasible.

• Since all data is stored on the Blockchain, it's easily accessible to anyone with an internet connection. There's no need for manual data entry or verification.

• The verifiability of records stored in Blockchain makes it easier to comply with privacy laws and regulations, such as GDPR (General Data Protection Regulation).

2. Accelerated Mobile Pages (AMP):

Mobile usage continues to be on the rise, and with that growth comes new opportunities for mobile-first web experiences. AMP allows mobile users to access the same content hosted on a website without downloading and viewing it. It helps improve the user experience by speeding up loading times and providing an enhanced browsing experience by providing more relevant content.

Benefits of Accelerated Mobile Pages (AMP):

• It reduces load time and latency by allowing pages to load much faster on a mobile device.

• It can provide a device-agnostic user experience. The same content can be displayed on devices like smartphones and tablets, providing the best user experience in content, design, and performance.

• AMP can dynamically compress the HTML, CSS, and JavaScript code stored on a website to optimise the file size for mobile devices. 

3. Internet of Things (IoT): 

The Internet of Things connects physical devices, vehicles, and even animals to the internet. The IoT allows for these devices to communicate with each other and with users through wireless connections, which lets them connect to a cloud service to facilitate interactions. It's predicted that the IoT will reach approximately 30 billion units by 2020.

Benefits of the Internet of Things (IoT):

1. It will be good for your business:

The interconnectedness of the IoT will allow for a vast amount of data collection about users and their habits, which can enhance user experience and improve infrastructure performance. 

2. It will be suitable for your customers:

The IoT will make it easier to connect devices with services and users, which means that devices can be connected remotely even when they're out of range (like with Alexa), making it useful for manufacturers and businesses to send information about their products.

4. Voice Search Optimization: 

Google has become a dominant player in the world of search, and with that also came the rise of voice search. The most recent version of Google's mobile app changed how they speak to users in English, going from formal and straightforward to a more conversational-sounding voice.

Benefits of Voice Search Optimization:

1. Higher efficiency:

Currently, it's used to bring down the number of searches and improve the accuracy of voice recognition. As this technology continues to be refined, companies can expect increased efficiency and productivity.

2. Better understanding of queries:

Google's deep website development technology will help get more accurate responses (such as utilising the context), leading to improvement in ticketing, customer service, and customer satisfaction. 

3. Higher engagement:

Voice search optimization will also help increase engagement with search (when users can understand what they're talking about), evidenced by the increase in the number of completed queries. 

5. Virtual Reality (VR): 

Virtual reality technology is growing at an incredible rate, and its uses were once limited by cost and technology, but now it can use IT on mobile phones! Can use VR for gaming, social media, tourism, architecture, real estate development, and even fashion. It's predicted that the global virtual reality market will continue to grow steadily, taking advantage of the vast potentials in many industries like medical, automotive, and retail.

Benefits of Virtual Reality (VR):

1. Education: VR can be useful for educators that want to take their students on a visual journey. It could be used in the classroom for lectures or field trips to provide a virtual environment for children to learn about geography and different cultures.

2. Humanitarian efforts:

VR can help in urban planning and can be used for humanitarian efforts. Real-time assistance can be given to people in the disaster area by sending them virtual content (e.g., how to handle a car accident).

3. Marketing: 

VR will also be a valuable tool for companies to provide an immersive experience for their customers. They will be able to walk through a building, go on a tour through history, or even take part in active community events. 

6. AI-Powered Chatbots: 

AI-powered Chatbots are getting more sophisticated. They can learn, perform complex tasks, and understand natural language. One of the first chatbots to be released was Google Assistant, available on Google Home and Android devices.

Benefits of AI-Powered Chatbots:

1. Reduce costs:

Chatbots will be faster and more efficient than a human, allowing companies to reduce costs without hiring employees. By cutting down on hiring costs, companies can expect an increase in profits and a reduction in their wage bill (due to less hiring). 

2. Improved Customer Support: 

Chatbots will be able to handle various customer service requests (e.g., questions about products, shipping details, or even just about the company). This will allow for a reduction in the number of calls and emails received, leading to an increase in customer satisfaction levels.

3. Reduce errors:

Chatbots are also capable of detecting and correcting errors, so they'll likely be able to see problems faster than humans sometimes and notify a human if necessary (to fix the mistake quickly).
