Helios Sun and Moon Position Calculator

By Chemical Wedding

This app is only available on the App Store for iOS devices.


Helios is a Sun Position Calculator that graphically represents the position of the sun or moon, 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 7 modes for the sun:

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 live camera image
Sun Path view which shows the path of the sun the old fashioned way
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.

An Essential Tool for Outdoor Photography

This app is essential for finding the best locations and times to photograph outdoor scenes such as bridges, lighthouses, buildings and cemeteries where sun angles and shadows can make or break the photo. The UI is loaded with information and controls, and it serves my purposes very well.

Overpriced and does not function well

The interface is not intuitive, the virtual sun and mob feature does not pop up automatically and it is ridiculously overpriced. Get photo pills instead- much better program.

Chemical Wedding's appare a joke

The name says it all. Their products are overpriced and with so many functional apps, there is no reason to keep this on my phone. Get photopills, cadrage and pcalc instead.
