We're very excited to finally reveal Helios Pro for cinematographers and photographers. Not only can you pinpont the position of the sun, the moon (and now) stars the way you can in Helios, we've also added Augmented Reality and light simulation magic into the alchemal mix. Now you can visualize exactly what shots will look like at any location, at any time of the year or day. You can see precicely how light will illuminate and the shadows will fall.


For landscapes we create a dynamic 3d mesh of the surrounding terrain and show how the light will change throughout the day across the hills, mountains and valleys.

For city photographers we download OpenStreetMap building data and render a 3d reconstruction of the buildings and streets. You can therefore see exactly how the light will strike the buildings throught the day.


New to Helios Pro are a number of tools to help with night photography. The new milky way section gives you three different ways of visualizing the stars at any location. It also includes a unique night-shoot planner designed to let night photographers plan Milky Way photography.

- Multiple tools to explore sun, moon, and star data.
- Light simulation on a range of virtual stand-ins.
- Scarily accurate alchemy and celestial mechanics.
- Night-shoot planner to see the optimum dates and times to shoot the Milky Way.
- Dynamically generated 3D models of landscapes, buildings, cars, trees (and of course, a dinosaur).
- Many tools will still work without reception.
- Multiple ways to export data.
- iPad and iPhone compatible

Excellent except for the clunky saving of pictures.

I’ve just started using this and after two days of experimenting I find that the saving the photos option is too slow. It’s a three step process for some reason and when you’re out in the bright light it’s not easy to see all the buttons.

That aside the 3 D model in Live view is excellent. If you’re shooting a car commercial this is a must. It’s as accurate as sun seeker which is pretty accurate when using the compass, but not perfect. If you have the sun already out you can calibrate from that and then it is an excellent tool.

I just hope they figure out the saving of the photos part, it’s the only thing I’m not crazy about with Artemis view finder too.

It’s the only reason I didn’t give it five stars.

Outstanding ability to set up aerial shots

The ability to fly a virtual drone with full controls over rendered topography, or 3D building mode during all points of the sun’s path, anytime of the year is indispensable for saving time setting up shots. The light pollution map is also very handy. However, the app is buggy and as of 3/1/19, the “virtual stars” mode is broken and will cause the app to crash on my iPhone X. The app can also crash if I take the virtual drone over mountainous ranges, and then over an urban environment very quickly while planning the camera up or down as the app seems to many times ‘struggle’ to keep loading the GPS tiles. Definitely hope the devs update these frustrating bugs and make it more capable as soon as possible, but if you’re in the market for a power photography app, don’t let these drawbacks dissuade you. Helios Pro has become one of my main go-to apps, even if I’m just shooting off my iPhone.

Developer Response ,


Many thanks for your note. We think we have IDed the virtual drone/ mountainous ranges ranges bug but would like to chat about about the virtual stars mode, etc. Might you have time to talk? Please email me at at your convenience.

Kind regards

An awesome tool for photographers, too!

I used the app to plan a natural light shoot for one of our agency’s largest clients, knowing I’d have little access to the location beforehand, and only a small window to capture content the day of, as we were paying by the hour for the space. With Helios Pro, I was able to time our shoot down to the minute, and plan for the positioning of all our subjects, bounces, and cameras with a scientific degree of accuracy. Needless to say, the lighting in every shot came out perfect, just as planned. Though it’s mainly marketed to cinematographers, I’d recommend this app to anyone hoping to capture consistently beautiful, natural light photography. 5/5 stars would buy again. Side note: the customer service is amazing.
