Acknowledgments

Our Gratitude

Building GPS Kit has been made possible by a rich ecosystem of developer tools, open-source software, cartographic standards, and outdoor enthusiasts. We want to explicitly acknowledge and thank the creators, engineers, and communities whose work powers our app and website.

Apple Developer Technologies

GPS Kit for iOS is crafted exclusively for Apple devices using modern native frameworks:

• Swift & SwiftUI — for expressive, responsive native iOS interface design and buttery-smooth interactions.
• CoreLocation & CoreLocationUI — for high-precision satellite positioning, coordinates capture, and privacy-first location permissions.
• MapKit — for rich native Apple Maps cartography, high-resolution satellite imagery, and seamless turn-by-turn routing handoff.
• CoreData & CloudKit — enabling instant on-device trip storage and private Apple iCloud sync with zero third-party telemetry.
• StoreKit 2 — providing secure, transparent in-app subscription and purchase management.
• TipKit — delivering contextual discovery tips without annoying popups.

Open Source Software & Web Stack

Both our native mobile applications and our web tools rely on open-source engineering excellence:

• Next.js (Vercel) & React (Meta) — powering this high-performance, accessible, and crawlable website.
• Tailwind CSS & Headless UI (Tailwind Labs) — providing modern utility styling and accessible component primitives.
• Framer Motion — enabling fluid UI animations and responsive state transitions.
• Inter Font (Rasmus Andersson) — providing clean, highly legible typography designed for computer screens.

Cartographic Standards & Geodesy

Our coordinate conversion utilities, altitude calculations, and waypoint formatting rely on open geodetic standards:

• WGS 84 (World Geodetic System 1984) — the standard coordinate reference system powering global GPS navigation.
• OpenStreetMap & Open GIS Communities — inspiring open geographic tools, standard notation (DD, DMS, DDM), and border-free coordinate utilities.

Legal & Policy Models

Our legal documents were structured and inspired by open-source policy models published under the Creative Commons Zero (CC0-1.0) Universal Public Domain Dedication, adapted specifically to reflect LukyLab's on-device privacy architecture and Czech / European Union law.

Inspiration & Community

Special thanks to our early testers, travelers, hikers, photographers, and explorers whose real-world journeys and thoughtful feedback continue to shape GPS Kit into a dependable, private travel tracker.
