Web Squalix is a mobile app development company that builds iOS, Android and cross-platform apps for businesses in Reston, Virginia and the wider Northern Virginia area. We work remotely with a dedicated team, schedule calls in your morning hours, and stay on the project after launch to handle updates and fixes. If you run a company in the Dulles corridor, whether a government contractor, a healthcare group, a startup near Reston Town Center or a growing services firm, you probably already know what you want the app to do. The harder part is finding a team that will build it properly, tell you the truth about timelines, and still pick up the phone six months after release. That's the kind of team we try to be.
We identify your target users, define the problem your app solves, and prioritize features for launch versus version two. You leave discovery with a clear project scope, a prioritized feature list, and an honest development estimate.
We create wireframes and interactive prototypes in Figma so you can experience your app before development begins. Early feedback helps refine the user experience and makes changes easier and less expensive.
We build your application in two-week development sprints, delivering working builds you can install and test on your own device. Regular progress updates keep you informed and give you opportunities to provide feedback throughout development.
We test your app on real devices across different screen sizes, operating system versions, and network conditions. Our quality assurance process helps identify bugs, usability issues, and performance problems before release.
We prepare your application for release and manage submissions to the Apple App Store and Google Play. We also help address store review feedback, resolve submission issues, and guide your app through the publishing process.
Our work continues after launch. We handle bug fixes, operating system compatibility updates, performance improvements, and new feature development to keep your application reliable as user needs and platform requirements evolve.
As a custom fintech development company, we deliver secure, scalable financial software that helps institutions modernize legacy operations, strengthen compliance posture, and improve day to day efficiency
Build high-performance iPhone and iPad applications using Swift. We focus on polished user experiences, deep device integrations, security, and native iOS capabilities for businesses across Reston and Northern Virginia.
Develop reliable Android applications using Kotlin, optimized for performance, security, and a wide range of devices. From customer-facing apps to business-critical tools, we build Android solutions around your users and business goals.
Launch iOS and Android apps faster with React Native or Flutter using a shared codebase. Our cross-platform approach helps businesses reduce development costs and accelerate time to market. Our ShowFar ride-hailing app demonstrates this approach with live GPS tracking and cashless payments.
Build healthcare applications with privacy, security, and regulatory requirements in mind. We develop patient-facing apps, healthcare professional platforms, telehealth solutions, and FHIR-based integrations, drawing on experience with our MediFlow platform for pharmaceutical teams and verified healthcare professionals. HIPAA-related safeguards are considered from the design stage.
Replace disconnected spreadsheets, manual processes, and email chains with purpose-built business applications. We develop field-service tools, employee apps, approval workflows, operational dashboards, and enterprise mobile solutions that help organizations across Northern Virginia improve productivity.
Enhance mobile and business applications with practical AI capabilities, including conversational chatbots, personalized recommendations, intelligent search, document processing, and workflow automation. We integrate AI where it solves real problems, improves user experiences, and delivers measurable business value.
Power your mobile applications with scalable backend systems, secure APIs, database architecture, and cloud infrastructure. We work with Node.js, Python, and Go, alongside AWS, Google Cloud, and Azure, to build reliable systems that support integrations, business growth, and enterprise workloads.
Keep your application secure, stable, and useful long after launch. We provide bug fixes, operating system compatibility updates, performance optimization, security improvements, monitoring, and new feature development, with ongoing support for businesses in Reston and the wider Northern Virginia area.

Building a mobile app in Reston often means juggling security requirements, tight timelines and stakeholders who need clear answers. We work with teams across Northern Virginia from our development base, so you get a dedicated team without the overhead of a local agency. Calls, standups and demos are scheduled around US Eastern hours, and we communicate over Slack, email and video calls, so you always know who is working on what. Ready to start? Book a free discovery call and we will map out your app together.
We talk through your goals, users, budget, timeline and any security or compliance needs, and tell you if an idea needs adjusting before you spend money on it.
Wireframes and clickable prototypes you can review early, including accessibility checks, so changes are cheap.
Agile sprints with regular demos. You see working software every couple of weeks, not just at the end.
Real-device testing, security checks and performance review before anything goes live.
We handle App Store and Google Play submission, including the review requirements that trip up first-time publishers.
Ongoing updates, monitoring and improvements as your user base grows.
We've built platforms where role-based access and verified identity were non-negotiable. One example is MediFlow, a cloud-native content platform that connects pharma teams with verified healthcare professionals. If your app touches patient data, we design with HIPAA requirements in mind. See our healthcare app development work.
Learning apps, student portals and training platforms for universities and professional programs. More on EdTech app development.
On-demand and logistics. Booking, tracking and dispatch apps. Our ShowFar ride-hailing platform is one example of live GPS and cashless payments working together.
Whether you have a fully scoped idea or just a rough concept, we're happy to talk it through. Tell us about your project and we'll get back to you with practical next steps, not a sales script.
Real-time ride-hailing & mobility platform
ShowFar is a ride hailing and mobility platform built specifically for the South African transportation market. Taking cues from established taxi booking solutions such as Uber and Ola, the platform lets passengers request rides instantly while giving drivers the tools to accept bookings, manage trips, and receive secure digital payments. Through advanced GPS and live location technology, ShowFar connects riders with nearby available drivers automatically, which means faster pickups and smarter route management. Passengers can book a ride in a few taps, watch their driver approach on a live map, get timely ride notifications, and pay by card without touching cash. Drivers get an equally thoughtful experience, with organized trip management, live ride alerts, optimized routes, and clear visibility into their earnings. The platform was built with scalability, performance, security, and everyday usability in mind, giving South Africa a mobility ecosystem that can grow with its cities.
Blockchain-backed agriculture supply chain platform
FarmAgro Chain is a digital agriculture management platform built to modernize how farmers, distributors, and warehouse managers actually work together. Before a platform like this exists, most agribusinesses run coordination through phone calls, spreadsheets, and disconnected systems that fall out of sync the moment a shipment gets delayed. FarmAgro Chain replaces that with a unified digital ecosystem covering intelligent crop monitoring, structured distributor coordination, warehouse inventory tracking, and real time order management, so everyone in the supply chain is working from the same information instead of chasing updates. The backend runs on Node.js, Express, and MongoDB, chosen specifically for the kind of high volume, frequently changing data that agricultural operations generate day to day. Secure authentication, automated notifications, and an API driven architecture support the platform as operations scale beyond a handful of farms into a full regional network. The result is faster decision making, clearer logistics visibility, and a supply chain that runs on real time data rather than assumptions and phone tag.
