Mobile Strategy

Defining mobile strategy

Our strategists will help you with user research, target persona study, competition review, requirement analysis, and technical feasibility to validate your business idea and scope for adoption.

Mobile app designing

Mobile app UI/UX designing

We produce the most delightful UI and trending UX to enable a high degree of user engagement and adoption. Also by providing hi-fidelity wireframes and interactive clickable prototypes, our team can discover and mitigate the risks in the conceptualization stage of the app.

Native mobile app development

Native app development

Native apps ensure a very high quality of user experience, along with harnessing the full power of mobile devices and the advanced features offered by the mobile operating systems. Also, native apps can handle computationally heavy operations like Augmented Reality, Image/Video Processing, Media Streaming, 3D Rendering etc. with great ease. Our team has rich experience in Native iOS App development (Swift as well as Objective-C) and Native Android App development.

Hybrid app development

Hybrid app development

Hybrid mobile apps can significantly reduce the time and hence cost of mobile app development & maintenance, as multiple mobile platforms can be targeted from a single code base. Hybrid App development is ideally suited for a simple UI/UX project; however, they can also access the device hardware features by using cross-platform APIs. Our team has proficiency in Cordova, Ionic & Angular framework and have built amazing hybrid apps including database driven mobile apps.

Mobile app testing

Mobile app automation testing

We use Katalon studio for the functional & regression testing of mobile apps. For the performance testing of mobile apps, we use Android Debug Bridge tool and for Xcode Instrument tool. All the issues found in automation testing are automatically reported and assigned to the development team, for validation and fixing.

Manual testing mobile app

Mobile app manual testing

We perform functional, regression and non-functional testing of the mobile apps. Testing is performed on emulators as well as on a large pool of real devices, covering a wide range of operating systems, resolutions & brands/models. We have an in-house developed, highly advanced mobile apps bug tracking system, to report & track mobile app bugs and issues.

Cross-platform app development

Cross-platform app development

Cross-Platform App development is an approach that allows a single codebase (up to 90 percent) to be developed for multiple platforms. We have the proven expertise to develop cross-platform apps which can handle computationally heavy operations using React Native along with ES6 and Redux. This tech stack allows us to interact with native UI controllers of the OS, thus enabling user experience which is very close to native apps.

Similarly, if you need to connect your store to your Accounting software, e.g. QuickBooks or Datev, we can advise you on how this is best achieved.

Mobile app maintenance and support services

Support and maintenance for existing mobile apps

We offer proactive & predictive app maintenance by using tools like Firebase, Crashlytics, TestFairy, HockeyApp etc. We track the performance of your apps and suggest corrective actions. Our engineers conduct periodical reviews of your app for the purpose of security audits, gap analysis & policy compliance. This is necessary to keep your app abreast with new iOS/Android updates, ever-changing App/Play store policies and new technology trends.

Mobile app optimisation

Performance review and optimisation

Mobile app performance check and enhancement is one vital aspect of mobile development, which requires a high degree of expertise, experience, and skillset. Our engineers collect & analyze the data to identify and mitigate the bottleneck along with suggesting the add-on features/functionality.

Mobile app marketing

App marketing

The success of a mobile app cannot be defined without achieving the desired adoption rate and user acquisition. We use app marketing techniques like the integration of Google Adwords, iAds SDKs to publish the ads on search and display networks, remarketing, conversion tracking, event analysis – those boost ratings and improve conversions.
