About Blue Hour (Solar Calculator)
The Blue Hour describes a period of dawn and dusk, when the sky is colored specially which is very interesting for photography. The duration and timing of the Blue Hour varies depending on location and on the date. In order to achieve optimum results and to plan in advance the app Blue Hour (solar calculator) has been developed.
The calculations are not only limited to the blue hour. Further information for sun and moon events can also be calculated. This includes information about sunrise, sunset together with data of the blue hour, golden hour and twilight times (civil, nautical and astronomical). Furthermore you can calculate information about moonrise, moonset and moon phases (calculated data are approximations of +/- 1 day accuracy).
In this app you can view data for multiple locations. These can be defined manually or automatically by getting your GPS location. Additionally you have the opportunity to manually set timezones of the locations, which can be helpful if you are planning trips to locations with another timezone than the one, where you currently are in.
Core features at a glance
- Calculation of sunrise, sunset and solar noon
- Calculation of moonrise and moonset + moonphase
- Calculation of civil blue hour
- Calculation of twilight times (civil, nautical and astronomical)
- Calculation of golden hour
- Visualization of the azimuth-data of sunrise, sunset, moonrise and moonset
- Visualization of the azimuth-data of sun and moon for specific time
- 5 days weather prediction
- definition of multiple locations, including current position (based on GPS)
- monthly forecast
- export of forecast-data to Excel-tables
- reminder for events
- homescreen widget
Note: the calculated values are approximations. Additionally it depends on weather situation, how good or if the blue or golden hour is visible.

Indispensable app for any sort of outdoor photography. I use it to get good skyline shots, but has great customization for whatever might be needed.

I'm in a photo group this year and this week's assignment is the blue hour. I know golden hour is coming up so I started looking at websites and apps that give times and I really liked this one once I tried it. I love the dark theme that's easier on my eyes, all of the different times and conditions collected, and it is readable and not overly cluttered or dressed up with cutesy icons.

Golden hour seems to be off by one hour. It is telling me it starts at the time every other source is telling me is sunset. For example today sunset is supposed to be at 7:47pm, but Blue Hour is telling me that golden hour is at 7:47pm and sunset is at 8:21pm. Maybe it is not taking daylight savings into account properly. I am in Sydney, Australia (Australian Eastern Daylight savings time AEDT). The app says the times are in LHDT, which I think is the same as AEDT.

Exactly what I need except it does not seem, and I say "seem" because I might not have found it, to let you set up a reminder for each sunset, only a particular one.

Does what it does well. I'd say it goes above and beyond in terms of the information it provides. I'd like to see a widget that counts down to the next golden hour, would net a 5 star from me.
