But the wave of Covid-19 pandemic has heightened its popularity and the impact it\u2019s already having is not showing any sign of going downward. Keeping all the forecasts in mind, the online grocery delivery industry will only grow in the coming future.<\/p>\n\n\n\n<p id=\"361c\">So, with the availability of top <a href=\"https:\/\/www.xicom.biz\/services\/mobile-app-development\/\" rel=\"noreferrer noopener\" target=\"_blank\"><strong>mobile app development companies<\/strong><\/a>, building an on-demand grocery app is not a far-fetched job. But with the fact that the top online grocery player\u2019s ability is to perfectly meet the surging demand of the users, how would you survive in the cut-throat competitive market? How you will position your app and build customer bases that can last well beyond the pandemic?<\/p>\n\n\n\n<p id=\"9bd8\"><strong><em>Before I disclose to you the tips to develop a winning on-demand grocery app, let me share with you my work experience with a client!<\/em><\/strong><\/p>\n\n\n\n<p id=\"2923\">A few weeks back, I was working on a project to build a local grocery app for the UAE market, that basically focused on connecting local stores with customers and handling the process of taking orders, tracking deliveries, and ensuring door-step delivery.<\/p>\n\n\n\n<p id=\"145f\">Initially, I felt this is a common concept that all the leading online grocery apps were following, so there was no need to reinvent the wheel. Just following the existing design pattern would enable the app to hit the market right away.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p>But the project was a big blunder!<\/p><\/blockquote>\n\n\n\n<p id=\"cb0f\">Because different markets required different app models that suited different cultures and the apps must be designed in that way.<\/p>\n\n\n\n<p id=\"a770\">So before you get straight into the process to <a href=\"https:\/\/www.xicom.biz\/offerings\/hire-mobile-developers\/\" rel=\"noreferrer noopener\" target=\"_blank\"><strong>hire mobile app developer<\/strong><\/a> for your project, it is important to go through these important tips to make your on-demand grocery app successful.<\/p>\n\n\n\n<p id=\"5805\">When you start planning your grocery app, make sure that your development strategy manages to match the supply and demand of the competitive market.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p><strong><em>Instead of just \u201ccopying and pasting\u201d the approach behind the existing products, you need to keep these tips in mind:<\/em><\/strong><\/p><\/blockquote>\n\n\n\n<h2 id=\"ce32\"><strong>Recommendation 1: Keep An Eye on Industry Players<\/strong><\/h2>\n\n\n\n<p id=\"057f\">The leading grocery retailers are not only popular among the customers but also many aspiring enterprises or business owners. By keeping a track of their success stories and failures, leading developers will help you better frame out your own grocery ordering and delivery app.<\/p>\n\n\n\n<h2 id=\"ebd3\"><strong>Recommendation 2: Develop a Scalable, Robust and Flexible App<\/strong><\/h2>\n\n\n\n<p id=\"488f\">According to the reports, the online grocery services that are best able to handle the surging order volume will likely remain popular among consumers after the pandemic crises. This is because consumers are likely to rely on those services that consistently bring them groceries.<\/p>\n\n\n\n<p id=\"772d\">And, <a href=\"https:\/\/www.businessinsider.in\/bi-intelligence\/news\/the-online-grocery-report-the-coronavirus-pandemic-is-thrusting-online-grocery-into-the-spotlight-in-the-us-here-are-the-players-that-will-emerge-at-the-top-of-the-market\/articleshow\/76095316.cms\" rel=\"noreferrer noopener\" target=\"_blank\">Walmart and Instacart<\/a> are best positioned to lead the post-pandemic market!<\/p>\n\n\n\n<h2 id=\"9389\"><strong>Recommendation 3: Delivery Services Are Adapting to Users\u2019 Current Needs<\/strong><\/h2>\n\n\n\n<p id=\"bffa\">Did you know, the adoption of home delivery and grocery pick-up services is already skyrocketing and reaching 70% higher volumes than before the pandemic? How?<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p>During pandemic, taking into account and understanding the changing user\u2019s needs, grocery apps have quickly evolved to offer:<\/p><\/blockquote>\n\n\n\n<ul><li>Innovative delivery options such as same-day delivery, pre-scheduled delivery, same-week delivery, and more.<\/li><li>Improved pick-up services that include contactless in-store pickup and curbside pick-up.<\/li><\/ul>\n\n\n\n<p id=\"679f\">Since software development companies are well-versed in the changing demands of the market, therefore, it makes sense to partner with them to increase your chances of getting successful.<\/p>\n\n\n\n<h2 id=\"dc78\"><strong>Recommendation 4: Offer Customized Menu Options and Eliminate In-App Scrolling<\/strong><\/h2>\n\n\n\n<p id=\"ef79\">In the space of online grocery ordering and delivery, applications like Instacart or Walmart are already offering grocery shopping experiences with pre-build menus, what\u2019s new you are bringing to the user\u2019s screen?<\/p>\n\n\n\n<p id=\"e299\">Customized menus can be a more unique option. Users can directly order what exactly they want without wasting any time scrolling through the grocery menu.<\/p>\n\n\n\n<p id=\"e0b1\">For that, you can <a href=\"https:\/\/www.xicom.biz\/solutions\/hire-developers\/\" rel=\"noreferrer noopener\" target=\"_blank\"><strong>hire app developers<\/strong><\/a> experienced in ML technology.

It doesn\u2019t matter how brilliant your app features are and how amazing your screen looks if it is not earning any money for your business.<\/p>\n\n\n\n<p id=\"c971\"><em>So commonly, reputed app development companies would suggest to go for these app monetization models:<\/em><\/p>\n\n\n\n<p id=\"b3ba\"><strong><em>Set a commission fee<\/em><\/strong> on each transaction. It is basically the approach for third-party grocery apps that build a platform where customers and grocers meet and app owners can charge a service fee on each transaction.<\/p>\n\n\n\n<p id=\"b1aa\"><strong><em>Charge a commission on delivery<\/em><\/strong>. On every transaction, an admin can charge a fixed delivery fee from both buyers and delivery boys.<\/p>\n\n\n\n<p id=\"b306\"><strong><em>Monthly or yearly subscription plans for vendors<\/em><\/strong>. To sell on a grocery marketplace or get the products listed on the app, the vendor has to pay a fixed amount of fees to the admin.<\/p>\n\n\n\n<h2 id=\"7c5f\"><strong>Recommendation 6: Integration of Smart Algorithms<\/strong><\/h2>\n\n\n\n<p id=\"4136\">With emerging technologies, shopping online has become a much easier and more overwhelming experience.<\/p>\n\n\n\n<p id=\"0cce\">Over the years, technology has come a long way. Through smart algorithm integration with the help of artificial intelligence, customers can automatically fill their shopping carts with all the ingredients they need for cooking a specific meal.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p>If you are wondering how this technology actually works and auto fill your cart based on the recommendation, then you need to know these two ways:<\/p><\/blockquote>\n\n\n\n<ul><li>Recommendation survey forms that need to be filled by the users manually while signing up for the app to help you understand their preferences.<\/li><li>Tracking the buying pattern of the buyers.

From here, they can click on any item listed on the menu page.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/250\/1*SM4vhztbDdScjux76D15Kg.png\" alt=\"\"\/><\/figure>\n\n\n\n<p id=\"4d36\">Once the user clicks on the item, they can select the quality of the product and add the item to the cart. Adding an existing item to the cart will result in increasing the quality of the item that\u2019s already in the cart. The best part about using the app clone of Walmart is, you can allow users to select the product from multiple grocers and vendors and be able to merge it in a single order.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img alt=\"\"\/><\/figure>\n\n\n\n<p id=\"4c77\">Once the user is done with the products adding to their cart, then they can click on the view basket button on the header to the complete order summary screen and determine the amount that they need to pay. After making the payment of confirming the order, you will get the screen, where you can change the location or allow the app to automatically detect the current delivery location.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/250\/1*zJsYHWVfoIhJJcGGsZjkJA.png\" alt=\"\"\/><\/figure>\n\n\n\n<p id=\"1e3d\">Geolocation feature is used by default to determine the user\u2019s location and in case, if it isn\u2019t accurate, then you can pick the suggested locations.

All we do is request the data from the server.<\/p>\n\n\n\n<p id=\"9949\">Open the <strong>src\/screens\/Grocerylists.js<\/strong> file and add the following. However, as you are using the React Native for the app, therefore, you can use the below command to build the grocery list screen:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/700\/1*R30_a4SiwD9VTbyM369sXA.jpeg\" alt=\"\"\/><\/figure>\n\n\n\n<ul><li><strong>ii) Grocery Details Screen<\/strong><\/li><\/ul>\n\n\n\n<p id=\"f26a\">Now, let\u2019s move to the screen showing the details of the specific grocery item. It allows users to select the grocery item and select the quality of the product to be ordered and add them to the cart. While it is easier to hire cross-platform app developer that can help you walk through the codes, but still here we provide you the quick code command for easy implementation:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/700\/1*8d_BAp7RQ9McupJw1jj7SA.jpeg\" alt=\"\"\/><\/figure>\n\n\n\n<ul><li><strong>iii) GlobalContext<\/strong><\/li><\/ul>\n\n\n\n<p id=\"f885\">As we have mentioned earlier, we are using the <em>React Context API<\/em> to create a global context in which we usually store data and functions that we need throughout the app. This helps you to avoid such common problems that you encounter while working with states such as prop drilling.<\/p>\n\n\n\n<p id=\"b2bc\"><strong><em>Here\u2019s a quick code command that developers can use for this step:<\/em><\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/700\/1*5nctwQu-Kq2jRJJ-OrkKzQ.jpeg\" alt=\"\"\/><\/figure>\n\n\n\n<ul><li><strong>iv) Order Summary Screen<\/strong><\/li><\/ul>\n\n\n\n<p id=\"c0f6\">Next, let\u2019s proceed with the order summary screen which displays all the items added to the cart and explains the payment breakdown. So start by importing and initializing the packages you need:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/700\/1*UAa90_h0yTmAOSIEa_TJ9w.jpeg\" alt=\"\"\/><\/figure>\n\n\n\n<ul><li><strong>v) TrackOrder Screen<\/strong><\/li><\/ul>\n\n\n\n<p id=\"4866\">Next, once you are done with order confirmation, now it\u2019s time to track orders. The track order screen will help you check the progress of your order via a map interface. The map will display the location of the restaurant from where the delivery is picked up and the location of the driver. You can easily track the distance in between.<\/p>\n\n\n\n<p id=\"97c0\"><strong><em>So here is the code command that you can use to build the track order screen:<\/em><\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/miro.medium.com\/max\/700\/1*0uHNzuXT8XEfXNhy_P39mA.jpeg\" alt=\"\"\/><\/figure>\n\n\n\n<p id=\"d954\">If you have noticed, when you put an order, you start receiving the delivery status messages for the order.
