Online Grocery App

4. Straight out Technology out of the Box

Here’s a way to distinguish yourself from the crowd in the marketplace. Beyond the traditional backend and front-end tech stacks incorporate smart algorithms into the application to provide an amazing user experience.


For instance, new technology like Artificial Intelligence can be used to analyze a customer’s purchasing patterns. It could help customers to fill their carts with the items they require on a monthly or weekly basis.


It is also possible to allow customers to arrange delivery according to an appropriate time frame. Paying attention to these particulars will help keep customers in mind and boost their loyalty to your company.


Additionally, make sure you choose the most appropriate tech stack to develop apps.

Technology Stack for iOS Apps:

  1. Programming languages like Objective-C, Swift
  2. Toolkit: Apple Xcode
  3. SDK: iOS SDK/p>

Technology Stack for Android Apps:

  1. Languages of programming: Java, Kotlin
  2. Toolkit: Android Studio & Android Developer Tools

Model of Development and Timeline


Choose if your team will use the iterative approach to development (waterfall approach) or the agile development model. This will impact directly the app’s durability along with Time To Market (TTL).

MVP Or Full Fledged Development

The minimum viable product (MVP) is created using the most essential features. Based on user feedback, additional features will be introduced to the application. Sometimes, features that are not needed are removed.


A fully-fledged app development means that all functions of the app are developed all at once. This could be risky and affect the company’s profitability should the app fail to succeed in the marketplace.


The aim is to build an application that is simple to use and loads quickly. Users won’t waste their time with an application that is very demanding to use.


A well-designed application will benefit your users and your business. Here’s how
