About this app
The Comet Book app clearly shows when Comets can be viewed and in which direction. The direction and elevation of a Comet can change noticeably in a day due to its fast apparent motion. The moon and a bright planet may be convenient as a guide to find the comet though they have large apparent motion, too.
This app determines where Comet is in the sky when it becomes visible at your observing site. You can easily start your observation of a Comet by using Comet Book as a guide to the direction and elevation of the comet.
In addition, the new “3D Solar System seen from Space” mode allows you to view the motion of Comets and planets turning around the sun. Please take a look the comet’s movement around our solar system.

The time is off by an hour in July at NYC. On Android version, but it is fine on iPhone version. If i look at location of the sun, the app shows it's below the horizon, however the sun doesn't set for another hour. Probably the app didn't take account of daylight savings time. I have to move the time in the app back one hour for accurate, current locations of objects in the sky.

Has a lot of potential however, it and inaccurate prediction of where the comment is, possibly because it may not compensate for where on the earth the user is or for the local time zone. Yeah but gives one location I went through a website and it gave me another location, and it was only when I checked the website that I was able to locate the comet. The way the app is structured is great and the display is great, so it has potential however this is a critical problem that needs to be fixed

Really cool application. I'm trying to figure out where comet Neowise will be in relation to my location and it's visible times. Great help for photography. The only problem is when using the drag bar to set day the app crashed and I ended up back on my home screen. It did this several times, but once I had the day set it seemed stable. Hope this feedback can help the Developer correct this problem. I'm running Honor View 10 Android 8.1..... Thanks Dev, Great app....
