A must-have app for photographers to get the perfect shot. Plan ahead, visualize and predict the position of the Sun and the Moon, the Milky Way, sunrise and sunset times, golden hour, blue hour, twilight and other special moments for stunning photos.

Just decide where you need the Sun, the Moon or the Milky Way to be and the app will show you the date and time when you can take this picture.

Ephemeris is an essential photo planning tool for landscape and outdoor photographers, nature photographers, milky way and astrophotographers.

Main features:


Determine the correct position of the Sun, the Moon and the Milky Way for any place in the world and for any date. Plan your photos with precision according to the received data. Easily determine sunrise and sunset times, the time of the golden hour, the blue hour, civil twilight, nautical twilight and astronomical twilight. Quickly check the detailed information about the objects (altitude, azimuth, shadow ratio, moon’s phases, calendar, etc.).


Predict and visualize the scene using the live augmented reality view of the objects and their movements in the sky. Check live projections of the Sun, the Moon and the Milky Way positions to predict the time they will be at a location in the sky you need for a beautiful photo.


Calculate the best time and date to capture the Sun, the Moon and the Milky Way at a location in the sky you need or catch the desired lighting (golden hour, blue hour, twilight). Plan ahead and get the data for a month, six months or a year.


Choose any date and time to view the position of the Sun, the Moon and the Milky Way at that moment. Check the times of sunrise and sunset, golden hour and other moments. This is a crucial photo planner tool for both professional and novice outdoor photographers.

Not sure what happened

I really like the app. It gives me notifications for astronomical events. I used to be able to see write-ups about the notifications but recently the ability to find those write-ups disappeared. I don't know why that happened but it makes the notifications useless. If not for that Id have given 5stars

FINALLY A REAL Ephemeris for ios

That’s NOT so incredibly expensive like other astronomical software and yet user friendly enough for a novice to begin learning! As for the other review complaining of the subscription: These types of programs require financial help to be created and maintained so in all sincerity if a 0.99 cent fee for a ONE WEEK TRIAL (which is EASILY cancellable through your iphone settings) is such a sticking point for you, then you always have the option of alternatives that don’t include trashing a company with a quality product that generously offers LIFETIME ACCESS FOR $9.99. Believe me no other software will offer this for that price! Happy Stargazing 🔭 💫
