Sloww: Sun & Moon Phase Clock

See daylight, twilight and moon events on a circular twenty-four-hour clock.

Our take

Good for a visual overview of the local sky day

Sun/moon rings, widgets and event notices make astronomical timing glanceable.

Keep in mind: Calculated timings depend on location and settings; display night mode is not calibrated vision protection or therapy.

What you can do

Good for

Limitations & considerations

Privacy & permissions

The developer says astronomical location stays on-device without analytics; location permission and any shared widgets still deserve review.
