What We Do

Built for iOS.
Built to last.

We design and develop native mobile applications with a focus on clarity, performance, and real-world utility.

iOS App Development

Native iOS apps built with React Native and Expo — fast, reliable, and designed for the App Store from day one.

AI-Powered Features

We integrate cutting-edge AI to make apps smarter — from intelligent search to real-time analysis and personalized experiences.

Privacy-First Design

We build apps that respect user data. Minimal collection, transparent policies, and secure architecture by default.

App Store Publishing

End-to-end support from development to App Store submission — including monetization, in-app purchases, and ad integration.

About Us

Small team.
Big standards.

blacklightapp LLC is an independent mobile app development company focused on building tools that help people navigate an increasingly complex information landscape.

We believe the best apps are ones that respect your intelligence, protect your privacy, and do exactly what they say they'll do. No more, no less.
