Mobile App Development
Company
Your app is usually the nearest touchpoint between your business and its customers. It must work every single time. Zennaxx as a trusted Mobile app development company develops iOS, Android and cross platform apps that are fast, intuitive and built to retain users.
Our Mobile App Development Services
We are a full-service mobile app development agency covering every major platform, providing you with the right expertise for your product. Choosing the right mobile app development platform for your project can help you make a good decision before you begin development.
Android App Development
Our android app development team builds high-performance native Android apps in Kotlin and Java for the entire range of devices, screen sizes and OS versions. Every app is built from the ground up to perform, battery efficient and meet Google Play requirements.
iOS App Development
Our iOS app developers build native Swift apps with Apple’s strict performance and design guidelines to deliver seamless and reliable experiences on iPhone and iPad. These apps are optimized for the latest iOS versions and the App Store requirements.
Cross-Platform App Development
If you want to build a single codebase and have it work reliably on both Android and iOS, then you need to think about cross-platform development. Our mobile app development experts build cross-platform applications that deliver consistent performance and user experience on both the platforms with lower cost and faster timeline than developing two separate native apps.
Flutter App Development
Flutter is also one of the most powerful cross platform frameworks out there today. It runs on iOS, Android and the web with near-native performance from a single code base. Our flutter app development creates high performance and visually sharp flutter apps that feel native on any platform it runs on.
React Native App Development
With React Native you can share application code across platforms, but still deliver the performance your users expect. Our Mobile app development consultants are experts in building React Native apps that integrate perfectly with native device features so you can have a consistent, responsive experience across iOS and Android from a single codebase that’s easy to maintain.
App Modernization
Technical debt accumulates in legacy mobile apps, slowing down releases and frustrating users. Our app modernization service will re-architect, re-platform or rebuild legacy mobile apps to enhance performance, security and maintainability without compromising the functionality your users depend on.
Progressive Web App Development
You don’t need to download PWAs; they work like apps right in your browser. Our Mobile app development specialist team builds progressive web apps that work offline, load quickly and feel native bridging the gap between web and mobile without the overhead of separate app store submissions.
AR App Development
Augmented reality will let you add interactive, real-world context to your mobile app, including product visualization, virtual try-ons, training simulations, and navigation overlays. We build AR experiences that are useful, performant and actually useful to your users, not just add-ons that get ignored after the first use.
IoT App Development
IoT mobile apps deliver that data in a way that your users can access and act on it. Massive amounts of data are generated by connected devices. We are a mobile app development agency that creates IoT apps that reliably communicate with hardware, process real-time data streams and surface insights in interfaces that are easy to understand and act on.
Salesforce Application Development
Salesforce enables mobile apps that provide sales and support teams with customer data, pipeline insights and case management on the go. We build custom Salesforce mobile apps that integrate directly into your CRM workflows, boosting productivity for field teams and reps working remotely without the need to be at a desk.
Wearable App Development
Smartwatches and wearables have their own screen constraints, performance requirements and interaction patterns. Our Mobile app development consulting services team builds lightweight, fast and truly useful wearable apps for Apple Watch and Wear OS, taking your mobile experience to the devices worn by your users all day long.
Cloud App Development
Cloud mobile apps can scale to your needs, sync data across devices in real time, and ease the infrastructure burden on your development team. Our mobile app developers create cloud-native mobile apps on AWS, Azure and Google Cloud, designed to grow without having to be re-built as your user base increases.
Ionic App Development
If you are a company looking to develop a quick, cross-platform mobile app with web technologies without sacrificing quality, then Ionic is a good choice. We build cross-platform Ionic apps for iOS, Android and web from a single code base. Excellent for internal tools, enterprise apps and companies that need to move fast and not break the bank on dev.
QA Manual/Automation
A bad mobile app release ruins your reputation and causes uninstalls. Our QA testing service includes manual functional testing, automated regression testing, performance testing and device compatibility tests to make sure every release meets the quality bar your users expect before it gets to them.
UI/UX Design
Mobile interfaces are constrained by small screens, touch interactions and limited attention spans. Our UI/UX design team creates clean, simple and engaging mobile interfaces that reduce onboarding friction, increase retention, and make sure every interaction in your app is meaningful and easy to navigate.

Frequently Asked Questions
Quick answers to the top questions companies ask about starting a mobile app project so you can move forward with confidence.
It is contingent upon the platform, complexity, features, and the team you choose. A simple app will generally cost $10,000-$25,000, a full-featured app with custom backend, integrations and advanced features anywhere from $50,000 to $200,000+. Understanding the key factors that influence app development costs before you begin your project will enable you to budget and scope realistically right from day one.
A simple MVP will take 8-12 weeks, whereas a fully featured app with complex integrations and custom design may take 4-9 months. At the first consultation we give you a phased timeline so you know what gets built and when not some vague estimate that changes after you’ve signed.
