Vela Design Group has added location services and a home location option to its world clock for the iPhone and iPod touch. VelaClock also has features of interest to photographers and astronomers: sunrise, sunset, and three kinds of twilight: civil, nautical, astronomical for both dawn and dusk, duration of daylight, moonrise, moonset, moon phase and tilt and more.

VelaClock displays a list of cities and corresponding local times. The rows in the city list can show a daylight bar that gives the user a picture of 24 hours of natural light (bright daylight, three kinds of twilight and night). The daylight bar (24 hours of light) may be centered at noon or the current time. A thin white bar indicates when the moon is visible.

VelaClock 1.3

Up to 50 cities of interest can be added from a selection of over 500.

New features in version 1.3 include:

1. Added support for Current Location. Users may add a "Current Location" place to their list of cities. The current location is re-calculated each time VelaClock is launched. If network access or GPS is not avalable, the last current location will be used. This feature is compatible with iPhone 3G, the original iPhone, and iPod touch.
2. Added a Home Location place. Users may enter city name, latitude, longitude and time zone for their Home Location. The Home Location is designed for users whose home cities are not included in the built-in list of cities.
3. Updated Daylight Saving Time rules for Argentina, Brazil, Mauritius and Syria.
