About this app

MRK01 Watch Face is a solar-themed Wear OS watch face built around the Sun and the natural progression of the day: sunrise, daylight, sunset, twilight, and a 24-hour solar ring.

IMPORTANT: For the complete MRK01 experience, install the companion app MRK01 Solar Support on your watch:
https://play.viewpro.live/store/apps/details?id=it.mmnz.mrk01.support

MRK01 Solar Support provides the solar and fitness data used by the watch face and handles location access, permissions, cache, refresh, and complication updates.

Without MRK01 Solar Support, key solar and fitness features may be unavailable or limited.

Key features:
• 24-hour solar ring showing dawn, daylight, dusk, and twilight around the watch face
• Sunrise and sunset times at a glance
• Live countdown to the selected solar event
• Current daylight duration
• Twilight visualization, with optional Blue Hour and Golden Hour segments
• Central digital clock with date
• Dynamic Moon phase background and phase information
• Weather information with condition, temperature, and UV index
• Heart rate and daily steps
• Battery information
• Ambient mode
• Support for configurable solar display modes

The solar ring is the heart of MRK01: instead of simply displaying solar information as numbers, it gives you a visual representation of where you are within the solar day.

Recommended setup:
1. Install MRK01 Watch Face.
2. Install MRK01 Solar Support: https://play.viewpro.live/store/apps/details?id=it.mmnz.mrk01.support
3. Open MRK01 Solar Support on the watch.
4. Grant the requested permissions.
5. Select or refresh MRK01 Watch Face.

MRK01 Solar Support is required for the full MRK01 experience, including solar calculations and fitness data.

Disclaimer: MRK01 provides solar, weather, daylight, twilight, heart rate, and step information for general reference only. Data may depend on location accuracy, permissions, sensors, cache, network availability, and system limitations. Do not use MRK01 as your sole source for navigation, mountain or marine safety, weather-critical decisions, or emergency situations. Always rely on official weather services, maps, nautical charts, dedicated navigation tools, and your own judgment when outdoors.

What’s new

MRK01 Watch Face release notes.
Maintenance update aligned with MRK01 Solar Support 1.0.2. The watch face layout and appearance are unchanged. Keep MRK01 Solar Support installed and updated: it now shows clear on-dial messages when GPS or location permission is missing, instead of leaving the solar arc empty.
