Washington, DC · App Development
We build iOS, Android, and cross-platform mobile apps that DC users actually love. From membership apps for DC associations to field tools for federal contractors — delivered on time, on budget.
Capabilities
We start with constraints: who approves work, what you must prove to regulators or boards, and how buyers actually decide. Delivery follows from that — not from a generic checklist.
Native apps built in Swift (iOS) and Kotlin (Android) for maximum performance and platform integration.
React Native and Flutter apps that run natively on both iOS and Android from one codebase.
Progressive web apps that feel native but install from a browser — no App Store required.
Scalable backend infrastructure, REST/GraphQL APIs, and database architecture for your app.
User experience design that reduces churn and increases engagement — Figma prototypes before code.
Ongoing support, OS compatibility updates, and feature releases to keep your app competitive.
Office on N Street NW. Most engagements pair DC stakeholders (legal, security, procurement) with a senior remote build team — clear owners, written decisions, and no bait-and-switch on who does the work.
Apps built with FedRAMP and FISMA considerations for government and contractor clients.
We've built membership apps for DC trade associations, nonprofits, and member-driven organizations.
Sub-2s load times, 60fps animations, and optimized battery usage on every app we ship.
