Blautime

Blue hour and golden hour

Know when the light will be blue, or golden.

Blautime does not take photos: it tells you when. For the place where you are and the date you choose, it shows the times of the blue hour and the golden hour, morning and evening, and its compass shows where the sun rises and sets.

Available on Android and iPhone.

The screens shown are those of the Android version, some features will come later on iPhone.

How it works

  1. Choose the place

    Use your position, or pick any place: search for a city, tap the map or type coordinates.

  2. Read the times

    Blautime shows the blue hour and the golden hour, morning and evening, with sunrise and sunset, for today or any date.

  3. Point the compass

    Turn your phone towards the scene: the compass shows where the sun rises, where it sets and where it is right now.

Be in the right place at the right time

Blue hour and golden hour

The exact time ranges, morning and evening, calculated for your position and the date.

The direction of the sun

The compass shows where the sun rises and sets, and where it is now: frame your shot before the light comes.

Any place

Your approximate position, a city among 7,000, a point on the map or coordinates.

Reminders

A notification before each blue or golden hour you choose, with the lead time you prefer.

Plan ahead

The next seven days at a glance, any date for a future shoot, and each phase can be sent to your calendar.

Moon and Milky Way

Moon phase, moonrise and moonset, and the astronomical night, when the sky is darkest.

Frequently asked questions

What is the blue hour?

The period of twilight, just after sunset or just before sunrise, when the sun is slightly below the horizon and the sky takes a deep blue colour, in perfect contrast with city lights.

What is the golden hour?

The warm, soft light just after sunrise and just before sunset, when the sun is low above the horizon.

Does Blautime take photos?

No. Blautime is not a camera app: it tells you when the blue hour and the golden hour happen and where the sun will be. You then take your photos with any camera, from a smartphone to a reflex.

Do I need an Internet connection?

No. The times and the compass are calculated on your phone and work offline. Only the ads need a connection.

On which phones does Blautime work?

Blautime is available on Android and on iPhone, without an account.
