Thanks for fixing the issue. Great app. I only wish this was working when Nowise was visible in my area.

Accurate positioning but... ... the autoscrolling is not too smooth. Not of a big deal, though. I was able to see Comet Love joy accurately because of this app.

Fanatics app! Really helpful for observing the Nowise comet! The 3D bird views are awesome, which illustrate the comets in the solar system!
★★☆☆☆Victor Sanchez· Jul 15, 2020
Just got back from taking pictures of Nowise. If I listened to this app, I would have missed it completely. The app said it would fall below the horizon around 9:30 pm. Couldn't be more wrong. That didn't happen until almost 11 PM. No point in usuing an app that isn't accurate.

The app closes as soon as I open it, have reinstalled it, restarted my mobile, but it closes on auto as soon as it opens

Website links under "Developer contact" in Google Play is broken. No reply to email link after 48 hours. Using the "Contact Us" in the app (buried at the bottom of the Support Page found from the Help menu) is tedious at best. Not worth the effort to use only to find that it doesn't work (confidence is not high that it will). The real problem is: the app is only showing two comets (neither of which are currently visible). And I cannot figure out how to add/update the comet information.
