Services

App development,
end to end.

4CYTE designs and builds high-quality mobile solutions for demanding, real-world environments — from first conversation to launch and long-term support.

What we build

Full-cycle mobile engineering.

One senior team across the whole stack — so the app that ships is the app you scoped, hardened and ready for the field.

Custom App Development

Tailored iOS and Android apps engineered to your requirements — full-cycle, from concept and architecture through deployment and maintenance.

Cross-Platform

When it fits, a single codebase for a consistent experience on every device — reducing time to market and long-term cost.

UI/UX Design

Touch-first interfaces built to Apple Human Interface guidelines, so the product is intuitive, engaging and easy to adopt.

Backend & APIs

Robust, scalable services with secure authentication, data synchronization and clean integration with third-party systems.

Maintenance & Support

Ongoing updates, monitoring and performance work that keep the app compliant with evolving OS ecosystems and running smoothly.

Testing & QA

Iterative, automated testing to find and fix issues before launch — so the app meets a high quality and reliability bar.

From vision to launch

A proven process.

A streamlined, client-focused path from first idea to a product in the store — every step planned and executed by senior engineers.

Have a conversation

We learn your goals, your workflow and your frustrations, and bring our engineering expertise to shape the right solution.

Propose a solution

A custom proposal with recommended technologies, a rough timeline and a cost estimate that defines the project specifications.

Design

Low-fidelity structure, high-fidelity visuals, then interactive prototypes for real user testing and feedback.

Develop · test · deploy

Agile cycles with continuous integration, regular feedback and clean deployment — robust, scalable, aligned with expectations.

Post-launch

We stand by our work with a warranty and stay available for future maintenance and optimization.

Why 4CYTE

Senior engineering, start to finish.

Architect-led

A senior mobile architect is on every engagement — not a hand-off to junior developers after the pitch.

Enterprise-grade rigor

Practices honed in CMMI Level 3, project-centric environments with PMI / PMBOK discipline.

Security-first

Application hardening, encrypted data and authenticated services — experience earned on cleared federal work.

Domain depth

HSE and OSHA compliance, geospatial and remote sensing, IoT, records management and emergency preparedness.

Client-centric

Customer-facing collaboration and short delivery intervals that cut rework and keep the work on the essentials.

We stand by our work

A proven track record across federal, state and private sectors — and support that lasts well beyond launch.

Technologies

Best-in-class tools.

Native where it counts, cross-platform where it helps — always with vetted frameworks and secure integrations.
