A personal project, built with the help of AI and shared for free. I tried to pack in as many features as the watch's 59.9 kB of memory could handle. There might still be some issues, as this is the first release. If you find any problems, please contact me and I'll fix them. Solar Frontier is a high-contrast watch face made pixel by pixel for the Instinct 3 Solar (45 and 50 mm). Two layouts (progress rows or a chart), two side-gauge styles, a round info circle and three top lines. Choose what every part shows, or switch it off. WHAT IT CAN SHOW Health: heart rate and zone, resting heart rate, breathing rate, Body Battery and its 2-hour trend, stress, steps, steps to goal, distance, calories, intensity minutes (today, with your own daily goal, and this week), floors up and down, metres climbed, move alert, Pulse Ox. Weather: temperature & precipitation chance combo (circle), feels like, dew point, humidity, wind speed and direction, rain chance, today's high and low, next 3 hours, tomorrow. With Open-Meteo* also: gusts, cloud cover, visibility, UV index and today's maximum, precipitation in the next hour (rain or snow, 15-minute steps), rain in the last hour and today's total (rain and showers), new snow in the next 24 hours, freezing level, thunderstorm risk, air quality, pollen**. Sun and moon: sunrise, sunset, time to the next one, sun elevation, day length and daily change, solar noon, golden hour, daylight left, solar intensity, moon phase and illumination, next full and new moon, days to the next solstice or equinox. Tactical: Zulu and second time zone, BMNT and EENT, first and last light, coordinates, altitude, barometric pressure with trend and 3-hour change, storm alert on falling pressure, countdown to a date and time (D-12 T-21:44), seconds. Watch: battery and days left, watch temperature, notifications, alarm, Do Not Disturb, phone connection. MORE In the Chart layout the chart can be replaced by one metric in large type. Wrist raise shows exact values, including the chart's highest and lowest value. The solar chart records only while it is shown, so it fills in over 1 or 4 hours. Dark or light theme. Follows your units and 12/24-hour setting. Settings on the watch or in the Garmin Connect app, with options grouped by theme and units in their names. * Weather source "Open-Meteo": free, no account or key. Updates every 5 to 60 minutes through the phone (shorter intervals use more battery). Thunderstorm risk is the atmosphere's storm energy (CAPE) over the next 6 hours, not a lightning detector. Weather data by Open-Meteo.com (CC BY 4.0). ** Pollen: Europe only, during the pollen season. Air quality and pollen: Copernicus Atmosphere Monitoring Service (CAMS) via Open-Meteo. PERMISSIONS Health data and heart-rate zones, location (sun times, local weather), background and internet (Open-Meteo weather only). No data is collected.
