app development

Our design philosophy revolves around anticipation & understanding of the end-user. Our app visualizers anticipate & predict how users are going to interact with our apps. This helps us create simple conversion-focused UIs that are centered around the user. We strike a perfect balance between form & function with our apps. We can customize your apps around the unique priorities of your products.

We have tried to keep our delivery model as simple as possible, leaving you to focus on other aspects of your business. We build our apps inhouse with our team of experts who work tirelessly to make sure we only deliver the highest rates of success with our apps.

We have an easy 4 step process when it comes to building our apps.

Step 1 - Sales Outreach

Our app experts will try to understannd your business needs & your requirements from your app. We will then conduct a detailed market research & project estimation to lay down a plan of action.

Step 2 - Designing

Our designers will then start working on the UI of your app. We use tools such as Adobe XD & Photoshop while designing app prototypes. The prototype will be sent to you for approval.

Step 3 - Development & Testing

After approval, the prototype is sent for development. After development is complete, the APK is forwarded to the Quality Analysts for testing. The APK goes through thorough testing where the QA experts test for bugs & glitches. The app is launched on the Play Store only after the final APK is approved by the client & the lead tester.

Step 4 - Launch

Once the app is launched on the play store, marketing efforts for your app will begin. Our marketers conduct App Store Optimization(ASO) & generate PR for the app. We also run paid campaigns for the app on Google Ads & Facebook Ads. We then offer the client with free support for upto 6 months after the app is launched.

We understand that the design & user experience of an app is as essential as the features it has. We put a great emphasis on design & ease of use to increase user trust & retention. Since competition among apps is growing with more businesses creating apps, great design is one of the best ways to make your app stand out. Our designers conduct detailed market research by looking at other apps in the client's niche. This helps us understand what kind of apps already exist in the market. Armed with this information, our designers use tools such as Adobe XD & Photoshop for designing app prototypes. The prototype is sent to the client for approval. Changes & alterations are made based on the client's feedback. Only after the client's approval are the prototypes sent for development.
We will be using technologies such as Android Studio, Java, Kotlin, Firebase, Retrofit, etc. for Android & Objective C, Swift & XC Mock for iOS. Our developers have between 3-10 years of industry experience, so rest assured that your project is in good hands.
