Apps for makers
Five apps for Wear OS and Android. Four are built for a craft I actually do, and one puts the live Earth and sky on a watch. They all work offline, and none of them need an account. They are in closed testing on Google Play, ahead of a public release.
Planetaria for Wear OS

Planetaria
A small desk globe with a round screen that shows Earth as it looks right now: today's daylight, yesterday's clouds from NASA, city lights at night, the Space Station and recent earthquakes.
It can also show the other planets, the Moon and tonight's sky, pop up the time and local weather, and play your own videos.
Coming soon
Lunaria
The Moon that's in the sky tonight, in its real phase, with the slight wobble and change in size it goes through every month.
Set it to a date that matters to you, like the night someone was born, and it keeps that night's Moon. It works offline, with no app or account.
