Helios is a Sun Position Calculator that graphically represents the position of the sun from dusk to dawn, on any given day, in any given place.

Designed as an aid to Cinematographers and Stills Photographers working in natural light, Helios is essential to anyone who needs to plan a day around the constantly changing character of sunlight. Helios works without a network connection, though some functions are enhanced when connected to the internet.

Gaffers, Grips, Location Managers, Production Designers and First Assistant Directors will already be aware of the value of this information. Other professionals, from Architects and Surveyors to Electricians and Landscape Gardeners can now predict sun exposure in the field, without the need for complex tables or graphs. This information can be emailed and then printed from within the application.

Helios operates in 6 modes:

HelioMeter - representing the direction of the sun on a compass dial, also indicating elevation and shadow length.
Virtual Sun View - showing the sun’s path overlaid onto the camera image
Map View - showing the direction of the sun overlaid onto a map of the location
Sky View - a representation of the sun's path across the sky
Inclinometer- determines at which times the sun will be at a certain elevation.
Compass - showing the azimuth of the sun in both degrees and time of day

While the accelerometer (inclinometer) and magnetometer (digital compass) of your iPhone are reasonably accurate, we think it wise to keep a high quality analogue device like the Suunto Tandem on hand for critical readings of elevation and azimuth.

sunlight direction superimposed over a map of your location in SkyMap View.

elevation and shadow length indicator in SkyMap View

a compass in Clinometer View that reads in time of day.

a new in-app comprehensive Users Guide.

We hope you like the improvements.

Bug fixes.

Version 2.0 (Jul 03, 2009)

This is a major upgrade with new features specifically requested by our users. We thank you all for your helpful and patient suggestions.

Skyview has been completely rewritten to make it interactive. You can now use a time slider to observe the path of the sun throughout the day in 2 minute intervals. This now gives people 3 completely different ways to look at the sun data.

By azimuth (the heliometer),
By time (the skyview)
By elevation (inclinometer view).

Skyview should be the default at the equator as the azimuth often doesn't change enough to make clear distinctions possible on the Heliometer.

You can now choose to start in the skyview automatically in the preferences.

Choosing a timezone in the custom longitude and latitude has been rewritten to make it much more intuitive. Simply choose a country and then the appropriate timezone.

Fix for Glasgow in the middle of summer.

Expand notes
Version 1.3 (Jun 15, 2009)

Sun representation near the equator has been completely reworked. Heliometer works from seamlessly Alaska to Kenya (inclinometer, tables and skyview always did).

Our European Friends can now have the date the way hey like it via the prefrerences.

Choose to start at current date automatically.

Fix for Am/PM

Expand notes
Version 1.2 (May 26, 2009)

You can now send an email from the application with full sun data for a day and location. This can be used for printing, call sheets and to distribute to other people on the crew.

Application preferences now lets you switch from 24 to 12 hour clock and turn off the magnetic declination offset. You can therefore use true north as well as magnetic north.

Changing the date now has a shortcut for current date.

Click on the time on the HelioMeter and you can chose to jump to a precise time without moving the sun.

Display of data for places nearer the poles has been fixed. Helios now understands if the sun sets after midnight and displays the correct length of day.

Expand notes
Version 1.1 (Apr 27, 2009)

New Inclinometer view of sun data. Now you can use the internal accelerometer to calculate when the sun will rise or set over a mountain or building and estimate when light will enter a window.

Shadow Factor was tweaked to be visually proportionate and allow you to better guess shadow lengths.

Interface tweaks.
