Circadian

Circadian : a watch face that adapts to your day.

Circadian is a minimalist Wear OS watch face (API 34+) designed to look clean, with a unique design. It automatically transitions between a bright Day mode and a calmer Night mode, so your watch always matches the moment.
You can even customize the timing as per your preference.

Key features:
🎨 10 built-in themes
Choose from 10 carefully designed color themes to match your style or your band. Each theme comes with a light face and dark face variant.

🌗 Automatic Day & Night switching
Set your own morning and evening windows (e.g. 4:00 AM–9:00 AM and 5:00 PM–10:00 PM), and Circadian will automatically do the transition.

🔋 Ultra-efficient Ambient mode (AOD)
Circadian's always-on display is built for low OPR (on-pixel ratio) so it looks sharp without draining your battery — pixel-perfect, all day.

⌚ At-a-glance info
Date, weather, heart rate, and step count are all shown clearly around the dial, so you get what you need without unlocking your phone.
