Glenby

Outdoor & Leisure • Hamburg

Our own product

Our own product: a microadventure app for Android with 14,702 GPS-verified nature tasks, end-to-end encrypted chats and EU hosting. Plus a bilingual marketing website built with Next.js 16.

Challenge

Outdoor apps almost always rely on competition, daily streak pressure and data collection. Glenby was built as the opposite: honest GPS proof instead of AI guessing, weekly streaks without loss anxiety, all data hosted in the EU. App and website had to come from a single mold.

Results

14,702 bilingual nature tasks with GPS verification
483 unit tests across 63 test files
Live on Google Play

Featured

3D marketing website and Windows desktop app for a Rust+ companion tool: Next.js 16, React Three Fiber, scroll-driven camera flight, Electron and Stripe.

Challenge

The client wanted a website for his Rust+ desktop tool that feels like the product: an instrument panel in the style of a Tektronix scope instead of a SaaS landing page. Full 3D, but without crashes on weak GPUs and without generic spinning logos.

Results

6 procedural 3D instruments, not a single imported 3D model
One shared WebGL context instead of nine (no context-loss crash)
Scroll video flight: 6 legs, desktop and mobile variants

Services
