How it works

Pick a city. Read the sky.

Dayclipse calculates the Sun and Moon for the place you choose, entirely on your phone. Here is what using it looks like, step by step.
  1. 01

    Choose a place

    On first launch, search for a city, region or country — or tap a popular location. The list is built in, so it works offline. You can change places or star favorites at any time.

    Dayclipse Choose a location screen with a city search field and popular locations such as New York, London and Tokyo.
  2. 02

    Read the live sky

    The home screen shows the next event with a countdown, the current period of light and a sky scene with the Sun and Moon. Drag the timeline to preview other times, or step to another date.

    Dayclipse home screen for New York: next event Sunset at 6:10 PM in 20 minutes, evening golden hour with the Sun 3.2° above the horizon, a sky scene with the Sun and Moon, and the day timeline.

    Go deeper when you need to

    Scroll down for the Sun, Moon and Events tabs. From the top bar, open the photography planner, share a sky card, or adjust settings.

    Dayclipse Events tab: filter chips, the next events list and the Sky Through the Day timeline with day, civil, nautical, astronomical, golden and blue bands.

The three detail tabs

Below the live sky, three tabs share the same moment and place as the dashboard. Drag the timeline and every card follows. You can choose which tab opens first in Settings.

  • Sun

    Sunrise and sunset, morning and evening golden hour and blue hour, the Sun's live position with a compass-aware dial, solar noon with maximum altitude, and total daylight.

  • Moon

    Phase and illumination, moonrise and moonset, live position, the Moon's altitude through the day, upcoming principal phases, an observing guide, Moon age, Earth–Moon distance and a monthly lunar calendar.

  • Events

    Next events, a layered Sky Through the Day timeline, daily totals for daylight, night and darkness, and the full agenda for the date. Filter by category, and choose which events and cards to show.

Tools in the top bar

Permissions and sensors

  • Location

    Not requested. You pick a city; Dayclipse never reads your GPS position.

  • Internet

    Not needed for calculations. Used when available for Firebase analytics and crash reports.

  • Compass & motion sensors

    Used to turn the Sun and Moon dials and for AR Sky View. Without a compass, dials stay north-up.

  • Camera

    Requested only when you open AR Sky View. You can decline and use the sensor-only view.

Compass accuracy varies between phones and near metal or electronics; Dayclipse shows a warning and calibration tips when readings look unreliable.

Carry the whole sky in your pocket.

Sunrise to moonset, golden hour to astronomical darkness — for cities worldwide, calculated on your phone.
