Circa: Natural Rhythm

Transform your iPhone into a circadian light alarm. Sleep better, wake up energized.

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 the sunset to promote melatonin secretion, helping you fall asleep naturally. • Gentle Wake Up: 30 minutes before your alarm, the screen gradually shifts from deep red to warm orange, then to bright white, signaling your body it's time to rise. • OLED Safe Technology: Our "Liquid Dark" engine physically turns off black pixels during the night. Minimal power consumption, total darkness. • Pure Interface: No distractions, no ads. Just the essentials for a peaceful night.

Respect your cycles. Wake up with CIRCA.
