Limina
Your space between states.
Precision audio for focus, sleep, meditation and deep rest — binaural beats, textured noise and rhythmic pulse, generated in real time, fully offline, with nothing tracked and nothing sold.
Limina is a founder-led project — I designed the product, built the brand, developed the app end to end, and took it through App Store submission and launch. Product strategy, UX, visual identity, audio engine architecture, pricing, and the privacy-first data model are all mine.
React Native + Expo, a custom real-time Web Audio engine, RevenueCat for subscriptions, and a fully offline, no-analytics data model. Live on iOS since July 2026.
Sound that guides your mind.
Limina generates layered soundscapes in real time — binaural tones, textured noise, pulse modulation, undertones and rhythmic beat patterns — all running locally on the device. Seven built-in presets (ADHD Calm, ADHD Focus, Work Focus, Stress Relief, Sleep, Dopamine, Meditation) give people a starting point; a touch-driven binaural pad lets them shape their own state from there.
A live binaural pad for dragging left/right ear frequencies in real time, with visible offset, band and delta readouts.
Six independently mutable/soloable layers — core tone, binaural depth, atmosphere, pulse, undertone, cycle beat — with a live orbital state visualizer.
No ads, no account, no analytics, fully offline. Mixes and session history never leave the device unless the user shares them.
