Sun Tracker|生產應用線上App不用買

Track the position of the sun throughout the day. Determine when sunrise will occur and then track the path of the sun through the sky until sunset. With tracking enabled the phone can be pointed at the sky to measure current elevation and azimuth angle.

New in version 2.0. Switch to the augmented reality vision mode and see the path of the sun overlayed on your environment. See exactly where the sun will go today and easily switch to the Solstice and Equinox paths.

Use the details page to calculate the Time, Elevation and Azimuth angle of:

* Astronomical Twilight (Dawn and Dusk)

* Nautical Twilight (Dawn and Dusk)

* Civil Twilight (Dawn and Dusk)

* Sunrise

* Sunset

* A user selected date and time.

The equation of time, Solar declination and Daylight duration are also calculated. All values are in the local timezone and adjusted for daylight savings if applicable.

Select a location on the map page or use the GPS to go to your current location. The map page also shows the direction and time of sunrise and sunset.

A useful tool for:

* Real Estate - When will the sun come over the hill? Will a tree or building block most of the winter sun?

* Gardeners - will the planting location suit have the right amount of sun exposure?

* Photographers - When will twilight occur?

* Architects - Maximise winter sun exposure and minimise summer heat gain.

* Solar panels - What angle and inclination should the panels be placed at to be optimal for the location?

The settings page allows you to toggle access to location data and provide an optional correction to the compass bearing.

Versions:

* 2.0

- Adds augmented reality sun tracking via the vision button. For best results enable the use of the device location and calibrate the compass before use.
