Observe the beauty of astronomy with Astropium

See all the main astronomical events on either 24- or 12-hour dial:
• sunrise
• sunset
• twilight (civil)
• visible day period
• visible day change
• moon phase
• moonrise
• moonset
• period moon is above horizon

Designed with infographics in mind:
• day of week indicator gives you a quick notion of remaining week
• battery bar is embedded in heliotropium logo
• colored charts provide better and quicker value perception

Designed with fitness in mind:
• steps and floors goal progress will be shown automatically when Activity Tracking is activated

Designed with efficiency in mind:
• all the astronomical data is calculated once per day and then being redrawn from the buffer
• all possible clock hand positions are hard-coded, so that your watch doesn't have to calculate anything

Designed with customization in mind:
• depending on your time format setting (12-hour or 24-hour) the watch face dial will be set accordingly
• in case 12-hour time format is selected, the dial will show astronomical events for the actual half of the day, terminated at 12PM (12:00), e.g. from midnight till noon you will most likely see dark blue bar for the night after 12, then light blue twilight bar and then yellow sun bar till 12, and at noon the watch face will re-render the data for the second half of the day (noon till midnight) showing sunset

Designed with heart: if this beauty and complexity of our Solar System was given to us for free, how can we charge you for just the tool that measures and displays its parameters? This watch face is free and will always stay free with full functionality! If you would like to support us and encourage further development, please donate at https://paypal.me/heliotropium

We are a nonprofit organisation and can provide tax exempt certificates on donations from €50.

Note:
Watch face uses last known location to calculate astronomical data. After a fresh start of watch, you may need to launch any location-tracking activity first to obtain position info. Watch face itself doesn't have permission to query location.
