MarsDevs has delivered production mobile applications since 2019, working with businesses that need dependable engineering across the entire mobile product lifecycle. Our teams select native or cross-platform technologies according to your users, business requirements, functionality, existing technology environment, and delivery objectives.
Mobile applications must perform under conditions that are difficult to reproduce in a simple demonstration. Users switch between networks, operate across different devices, install new operating system versions, and expect the application to remain responsive throughout. Our engineering process accounts for these real-world conditions throughout development.
As a mobile app development company in New York, MarsDevs works directly with business leaders, technology leaders, project stakeholders, designers, and internal development teams. From requirements and technical planning through launch, integration, and continued optimization, we provide the technical capabilities required to create a mobile application that can evolve alongside your business.
What We Build
Native, cross-platform, and hybrid engineering supported by the backend systems, integrations, and quality practices required for production.
We create iPhone and iPad applications using modern Apple technologies with attention to performance, interface behavior, device capabilities, and App Store requirements. Every component is developed around the intended user experience instead of treating mobile as an extension of a web application.
Our Android engineers build applications designed to work across a diverse range of devices, screen sizes, and operating system versions. We account for performance, responsiveness, device capabilities, and platform-specific interaction patterns throughout development.
React Native and Flutter allow businesses to develop experiences for iOS and Android from a shared development foundation. We assess the product before selecting the framework so the technology supports your functionality, release strategy, and long-term maintenance needs.
For products that benefit from web-based technologies while still requiring a mobile application experience, hybrid development can provide a practical route to multiple platforms. We create applications around the capabilities, performance requirements, and distribution needs of the product.
A mobile application depends on reliable services behind the interface. We build authentication, APIs, notifications, data synchronization, backend services, and supporting infrastructure that allow your application to communicate reliably with the systems it depends on.
Older mobile applications can become difficult to maintain as platforms, user expectations, and technology standards change. We assess existing applications and create modernization or migration strategies that improve the technical foundation while preserving important product functionality.

← Click to exploreFrom manual ECG reviews to AI-powered diagnostics at scale.
Overview
A US-based healthcare SaaS company was struggling to scale its diagnostic review process as patient volumes grew across 40+ hospital networks. Cardiologists were the bottleneck — each ECG review took over 3 hours manually, creating dangerous delays in time-sensitive diagnoses. MarsDevs built a multi-modal AI platform that processes ECG images, extracts clinical patterns, and delivers ranked diagnostic alerts in under 60 seconds. The system integrated seamlessly into existing EHR infrastructure with no workflow changes required from clinical staff. Within six months of deployment, the platform had reduced review times by 74% and was processing thousands of ECGs daily across the network.

Our teams combine modern development practices with product-focused thinking to create applications that support the way your business operates.
Mobile Application Development
A complete mobile product capability spanning platform engineering, experience design, backend systems, quality, and launch.
We build iOS products around Apple's platform conventions, device capabilities, and current application standards. The engineering process covers application architecture, interface, functionality, integrations, testing, and preparation required to take the product toward launch.
Android products need to account for differences in devices, screen dimensions, hardware configurations, and operating system versions. We build applications with platform-aware engineering and testing so the experience remains consistent across the devices relevant to your audience.
For businesses seeking shared development across mobile platforms, React Native and Flutter can provide an efficient foundation. We select and configure the technology around the application's functionality, existing technology environment, performance requirements, and long-term maintenance needs.
We develop the server-side systems that support mobile functionality, from secure authentication and data access to notifications and synchronization. The backend architecture is designed to work with the application's requirements and the wider technology ecosystem.
Mobile users expect familiar interactions, clear navigation, and interfaces that work naturally on smaller screens. Our mobile and design teams create mobile experiences around platform conventions, accessibility, usability, and the specific tasks customers, employees, or other users need to complete.
Getting the application built is only part of the launch process. We help prepare the mobile product for distribution by addressing store requirements, application metadata, screenshots, testing, release configuration, and the technical steps surrounding submission.
Mobile testing needs to account for actual devices, operating systems, connectivity conditions, permissions, notifications, and application states. We test critical functionality across representative environments to identify issues before they reach users.
We help businesses modernize applications built on older frameworks, architectures, or platform technologies while maintaining continuity for existing users and business operations. The process begins with understanding the current product and its dependencies before defining a practical path toward updated technology, improved performance, and maintainable code.
Applications used in changing network conditions need to manage local information and synchronization intelligently. We can design offline-capable experiences with local storage, background synchronization, and conflict handling suited to the application's data model and user workflows.
Since 2019, MarsDevs has delivered software products for startups, growth-stage companies, and enterprises across multiple industries.
