Few points about Progressive Web Apps

To expand with web application or mobile application is the most common trend these days, as it is the fastest platform to correlate the users rapidly and even for users it is high time-saving as it is the one-stop solution, where varied kinds of stuff are obtained right at one location or website or click or mobile app.


Build as Web, Act as App

Progressive Web Apps (PWAs) have swiftly embraced the web application market with its ability of quick execution on mobile devices and even streamlining in both online and offline mode. PWAs are implemented utilizing HTML, CSS, and JavaScript to make a level of ease of use and execution that is way faster than local versatile applications. They are highly responsive, take lesser information and storage space.

Google introduced PWAs for those enterprises who have a responsive web app and want that their end users get feel alike Native apps (that too without developing the mobile application).

Huge players namely – Flipkart Lite, Olacabs, Snapdeal, Makemytrip, Aliexpress, Alibaba, Trivago, Jumia, Redmart, Goibibo and much more already adapted PWAs and found major changes in their conversion rate, bounce rate, new customer acquisition, user-generated ad revenue, page load speed, impressions per visit, average user session length, completion rate, pages per session.

Outcomes of PWAs acceptance are very profitable with mind blowing boost to the existing web application.

Technologies for Progressive Web App Development

To build your PWA, two main building blocks which you should add in your application are:

  1. A web app manifest file
  2. Service-worker file


1. Web App manifest File

Mainly, the web app manifest file is JSON file that contains the data like name, short name, icon, background-colour, start_url of PWA. The web app manifest file is to provide information about web applications. That means the browsers detect the data information for how to display your application when it’s saved as Shortcut to Homescreen.

This “manifest.json” file is linked to theof your site.

2. The Service Worker

The service worker is JavaScript file which react in background process and perform few tasks like,

  • Check the network availability and display some response according to the network state which is no network or/ network connection available
  • Rendering Push notification
  • Add application data into the browser cache when online and get that data when offline

The service worker is automatically installed in the browser and it is independent of the application and run in some event like push notifications, connection changes, network availability or more. Firstly, need to register the service worker to keep active and get some response.

When the user first time loads the page, the service worker “install” event triggers. At that time all the static assets are stored in browser cache. In the service worker “activate” event, the service worker update when is there any changes in app shell and in the last “fetch” event, if is there any cache assets are available in the browser that catches to serve the app shell.

Straining for restraint

There are more users to use PWA in different types of the mobile browsers, so at times it is more complex to maintain the records of all browsing and visiting users. This can be overcome with new updates and brainstorming well before Progress Web App Development.

To Build a simple Progressive Web App

For building the demo structure of first PWA, I developed first one as WeatherInfo from the refrence url is https://developers.google.com/web/progressive-web-apps/

After the successful implementation, I am now developing PWA about news information for which steps are as mentioned below with a brief:

First, create an index.html file and add the manifest.json into the head tag of your site. Now add the given code in web app manifest file,


  "name": "news",
  "short_name": "news",
  "icons": [{
    "src": "images/icons/icon-128x128.png", \\ something is your directory path
      "sizes": "128x128",
      "type": "image/png"
    }, {
      "src": "images/icons/icon-144x144.png", \\ something is your directory path
      "sizes": "144x144",
      "type": "image/png"
    }, {
      "src": "images/icons/icon-152x152.png", \\ something is your directory path
      "sizes": "152x152",
      "type": "image/png"
    }, {
      "src": "images/icons/icon-192x192.png", \\ something is your directory path
      "sizes": "192x192",
      "type": "image/png"
    }, {
      "src": "images/icons/icon-256x256.png", \\ something is your directory path
      "sizes": "256x256",
      "type": "image/png"
  "start_url": "index.html",
  "display": "standalone",
  "background_color": "#3E4EB8",
  "theme_color": "#2F3BA2"

As shown above, the JSON data like name, icon, display, start_url are defined in the manifest file and are retrieved when the web application is saved as a shortcut to Home Screen.

After adding the web app manifest file, now need to add service worker file in the application which is more important to build the PWA. First of all, need to register the service-worker in the browser. For that, add the below-mentioned steps in the app.js file:

if ('serviceWorker' in navigator) {
                .then(function () {
                    console.log('Your SW Registered');

After that need to install and activate the service worker in the browser, so add the given code to the service worker file:


/* For install the service worker */
self.addEventListener('install', function (e) {
    console.log('Install SW');
            caches.open(newsCache).then(function (cache) {
        console.log('Caching app shell');
        return cache.addAll(newsfiles);
/* For activate the service worker */
self.addEventListener('activate', function (e) {
    console.log('[ServiceWorker] Activate');
            caches.keys().then(function (keyList) {
        return Promise.all(keyList.map(function (key) {
            if (key !== newsCache) {
                console.log('[ServiceWorker] Removing old cache', key);
                return caches.delete(key);
    return self.clients.claim();

Here, newsfiles variable comprises of files like HTML, JavaScript, CSS which developer wants to cache. Here, NewsCache represents the name of the cache store in the browser.

Now, the App Shell is the simplest design pattern in which initially an app UI is loaded and then after the app content is loaded. when the app UI is loaded, immediately the design is store locally. Later on, after some time to run the app, the Shell files are loaded from the local storage and at that time app is loaded quicker compared to the initially loaded ones.

After that, developer requires to fetch the all data content from the cache, when the network status is offline. So, for it includes some fetch function content into the service worker file itself.

self.addEventListener('fetch', function (event) {
            .then(function (response) {
                return response || fetch(event.request);


Firstly, we required checking whether the network connection is available or not. For that progressive web developer need to add the simple offline.js file to verify the internet connection. To be precise, this file is defined at the end of the body of the index.html file.

(function () {
    'use strict';
    window.addEventListener('online', function (e) {
      //  document.querySelector('.add').removeAttribute('hidden');
        console.log("You are online");
    }, false);
    window.addEventListener('offline', function (e) {
       // document.querySelector('.add').setAttribute('hidden', true);
        console.log("You are offline");
    }, false);
    // Check if the user is connected.
    if (navigator.onLine) {
        console.log("You are online before app loaded");
    } else {
        // Show offline message
        console.log("You are offline before page load");

Now in the demo newsinfo application, the News data is retrieved from the Rest API which is in JSON string formation. In the first step, when the app is loaded, News data is stored in browser’s local storage. Then, News data is separated in card template and when one clicks on any particular newsinfo card, it displays complete information about that News like Title, Description, Created Date, various types of News along with visual information like images, videos, etc.

If offline mode is enabled then it triggers fetch event and returns the data from the cache, if network request fails. In this PWA including some features like adding fresh News data into the given Rest API in online mode.

Benefits of Embracing PWA

Core advantage of PWA is no need to install a mobile application from the App Store but still have the feel and experience like a mobile apps – so less space consumption and lighting loading speed similar to AMP (if integrated). Apart by, it runs and loads in both – online and offline mode, so internet is never an obstruction to load the information and for the enterprises to stay constantly in connection. Progressive Web App is usually installable apps not from app-store apps but as background operating functionality with service worker, faster load time with App Shell and put in Home Screen icon with the manifest also engaging Push Notifications and also easily Searchable in any search engines.

What’s new in Android Wear 2.0

Tradition that watches just tick tock time updates are far way older, now with booming penetration of Wearable technology and that too specially Fitbits and Smart Watches, wearable application development got new wings to evolve the market with a bright enterprise engaging future.

Android wear

To know the steps you walk or calories you burn or to send a message to a friend or to receive a call or weather forecasting update all are possible through wrist band or watch. Alike smartphones, users can stay more interactive with smart watches to perform their daily tasks through touch or just voice assistants. Android Wear and Mobile phones are interconnected via Bluetooth.

Apple watches are always into buzz since years, but Android watches are also not back these days. Google with each update continuously endeavors to come up with new functionalities that bring up a new trend in Wearable Technology and boosts the acceptance rates.

New in Android Wear 2.0

Google’s recently released a new Android Wear update which brings more watch faces, an on-watch version of the Google Play Store, interactive messages and the new Google Assistant to wrist. More updates for Android Wearable app Development companies and users comprise of:

Adapting Material Design Concept

The material design concept is mainly optimised in Wear watches for redesigning the app launcher and making it reconcilable with round screens. Say no to left and right swipe to search apps, simply push side button and the slight arc will be displayed.


Hold and drag favourite apps to make it visible first. New context specific action drawer is also added in new Wear update. Menus are much accessible with rotational input. It is highly recommended to follow the norms of Material Design for outstanding Look ‘n’ Feel.

Standalone Apps and Play Store

To access the watch app it was necessary to connect it to the mobile phone, but it is all older now. Android Wear 2.0 brought phenomenal change to Wearable ecosystem with Standalone apps. Standalone apps are where a user can download the wearable apps right from the play store in watch and no need to download it in the phone and then sync it.


Security is always a worrying factor in such purposes, but Standalone apps are highly secured as they connect to Wi-Fi. For it, watches use secure transfer authentication data via the Wearable Data Layer API – username and password.

Read and Respond

To send messages from small screens is tough, isn’t it? So, Google announced an update where a message can be typed by swiping through the small keyboard. Google offers it native keyboards and also allow third-party keyboard apps for alternatives.

And that’s not all. Quickly read messages from notification and discreetly respond it by dictating, typing or handwriting your answer, or drawing an emoji. Intelligent and instant suggestion for response is also available with Smart Reply. Social apps like Facebook Messenger, Glide, Google Messenger, Hangouts, Telegram or WhatsApp already updated it for smartwatches.

fitnessFor working out with Music, make a playlist in music service like Spotify and play it straight from Wearable Homescreen – no need of the smart phone. If the watch is connected to a cellular network, then calling and messaging functionality are also available.

Android Pay

Google eventually started matching steps with Apple. Google powered Android Wear version 2.0 with Android Pay feature. Pay directly from wrist. Store the card details and tap the watch to pay the amount.


To enjoy contactless payments, it is mandatory that Android smartwatch comprises of NFC technology and is updated to latest Android Wear 2.0. It is essential to have Android Pay app in the mobile phone.

API integrations and upgradations

For developers, Google came up with new APIs and SDKs to integrate into application development to make apps more effective, swift and secure and to add on more advanced features in it.

Maps Navigation

Alike, Google Map Navigation in Mobile, your watch also redirects the map location and help to reach the desired destination along with its related information.

map-navigationClick google maps or command through voice to open, and enter the destination and mode of transportation and press navigate button. Google Maps card will appear and will navigate the path to the destination. No need to open the open to check the direction, Android watch will guide you.


Google notification cards disguised watch faces earlier, but not notification work bit differently. Now, it will show smaller icons instead of huge messages with a progress bar on bottom display to show left over cards in the stack.


Swipe up to view the notification clearly. Also, the text colour combination of notification cards is changed. It is featured accordingly that it changes with light and dark background to save battery life and dwindle the invasion of bright notifications.

Many of the smart watches are already updated with Android Wear 2.0 while few of them are still waiting to receive the relevant updates and functionalities.

How to be Profitable with iOS Apps Development

Because iOS is the most popular platform today, more and more software and mobile app developers are developing apps for the platform. The key to succeed in this endeavor is to find a niche or an ongoing trend and of course plenty of research on the web.

Over the years, the mobile market has grown considerably and experts predicted continued growth of the market. The usage of mobile internet surpassed desktops in the year 2014 and eight percent of web users have smart phones. With these impressive numbers, it is no wonder why popular and reliable companies all over the world are trying to get a piece of the modern day gold rush.

Profitable with iOS apps development

Among the platforms today, the iPhone or iOS platform is the most popular. That is why many mobile app developers are engaging into developing applications for the iOS platform to be more profitable. The following are some tips on how to be profitable with developing apps for iOS.

  • Find a niche or an ongoing trend. Make use of all the freely-accessible information on the web. Make sure to check what is selling at present and open iTunes and check out what applications are in every category of the app store in the top 100. Look at what’s selling and if you think there are still some dollars for another app of the kind, then it is safe to go ahead with it.
  • More work does not always mean more profit. There are really niches that are big in the market, but it does not always mean that the more work a developer puts into the project, the more profitable it will be. It is important to get to know the competition and make sure they do not have a great advantage in terms of sales.
  • Make sure the app is not existing already. This is probably the very first and most common mistakes that developers do. If an idea comes to mind, considering opening iTunes and spend fifteen minutes to do research.
  • Name it correctly. Most likely, the most difficult task is to come up with a reasonable or catchy name. It should be unique and should say what the application is all about within one or three words. Furthermore, it should be international. Search everything with Google first.
  • Two seconds is what it takes to turn a visitor into a customer. Most iTunes visitor or the app website will have made up their minds whether to buy or not after the first couple of seconds. Visitors could stay longer on the site, browse around even to check out testimonials, but would rarely change their minds after the first decision. The most valuable marketing assets are the app name and icon since there are what the visitors will see first. Consider highlighting all the great features in the app description. If the icon is catchy, the screenshots should be too since these are the next things that people will look at.
  • Avoid an over complicated app. Never make users feel or even worse pay as if they were using a rocket. This is because there are a lot of apps out there and if the users are challenged or become uncomfortable, they will just look for another at a minimal price.
  • Use a framework and do not invent the wheel. The thing is the effort that is put into an application and whether a developer could spend less time and get better quality at the same time. There are many frameworks around, some are supported commercially yet still free to use and some are community developed which still provides plenty of opportunities for troubles in forums.
  • Decide on a business model before proceeding to work. Before putting any time on designing an icon, hiring freelance copywriters, coding and more, make sure to know what the business model would be. Furthermore, make sure to feel comfortable with it and the app should have a realistic possibility to provide some income.
  • Avoid using valuable time on a dead cat. Almost all applications have the same sales graph. Release, then quite for a few days and skyrocket and sink slowly towards a plateau near the bottom. There are numerous tricks to make the sales’ peak unload more applications. Once it hits the bottom, it would never be a hit application anymore.
  • Make fuss about the app. Do not rush into selling. Make friends, family and colleagues know you are releasing an application for the iPhone. Make sure to follow them up when the app is released.
Boost customer service through mCommerce

To improve customer service, retain new customers and engage existing ones, a business must embrace the mobile trend. These days, shoppers no longer use a single device or platform for purchasing decisions. As a matter of fact, mCommerce is one of the biggest drivers behind eCommerce sales.
