iPhone
Every sound is synthesized live on your iPhone — rain that never repeats, ocean that never loops. Infinite by design. For rest, focus, and calm.
Every sleep app plays the same 30-minute file on repeat. Your brain notices.
Noctra doesn't loop — because there's nothing to loop. Every sound is synthesized live on your iPhone, generated fresh every second, forever. The rain at minute 400 has never been heard before.
INFINITE BY DESIGN
• 8 living soundscapes: Rain, Ocean, Wind, Womb, Fan, White, Pink, Brown
• Zero audio files — pure real-time synthesis
• Never repeats. Ever.
BUILT FOR NIGHT
• Sleep timer with a gentle 60-second fade (15–90 min or custom)
• Keeps playing with the screen locked
• Lock screen controls
• Nightstand mode: dim breathing clock with red-shift for night vision
MIX YOUR OWN
• Layer up to 3 sounds — rain over brown noise over a distant fan
• Per-layer volume, your perfect blend
PRIVATE BY DESIGN
No account. No tracking. Nothing collected. Works completely offline — forever.
