Circa: Natural Rhythm

The biological alarm clock that respects your sleep. Sunrise simulator and soundscapes with no subscriptions.

Discover CIRCA, the biological alarm clock designed to respect your natural rhythm.

Unlike standard alarms that shock you awake, CIRCA transforms your nightstand into a beautiful dawn and dusk simulator.

KEY FEATURES: • Natural Sleep Onset: A deep red light mimics dusk to promote melatonin secretion. • Gentle Wake-Up: 30 minutes before your alarm, the screen simulates a sunrise, shifting from red to warm orange, then bright white. • High-Fidelity Soundscapes: Fall asleep to the sound of gentle rain, a crackling wood fire, or ocean waves. • OLED Safe Technology: Our "Liquid Dark" engine physically turns off black pixels. Minimal battery drain, total darkness. • One-Time Purchase (Premium): No hidden subscriptions. Unlock the full sensory experience once, for life.

Respect your cycles. Wake up with CIRCA.
