Might be the coolest App ever made

I love this App so much!!! Hard to find the right words for why, but using it is quite meditative. I think it’s one of the best ways our knowledge and technology have been utilized in recent history. Of course nothing beats looking at the actual stars and planets if you have the opportunity, but this App gives such beautiful perspective and the amazing potential to reawaken interconnection. I don’t think most people contemplate the measurement of time and our place in the universe because there are so many distractions in modern life—but this gives me hope that staring down into a phone can actually enrich the way I look out and up into the rest of the world. Thank you for this App!

Great Product

I just started using the app. What would be nice is a manual that one could print instead of using the Share icon and selecting PRINT while viewing the instructions. Printing with Share messes up some of the pages due to the black filled headings. Maybe a night light capability if used in bedroom so it’s not so bright.
Much easier to learn aspects if there was a formal manual.
After going to cosmic-watch website on my laptop, I found the manual for printing as well as a quick start guide and tutorials.
I take back my initial comment on manuals.

Astrology Essential

I been using this app for months now, almost on a daily basis. What could make it a little more efficient would be to add notifications for direct and retrograde motions. Other wise it’s been an essential to my study. Perhaps an update on the geocentric and topocentric toggle, when switching to geocentric then clicking realtime the sky gradient reappears and topocentric triggers. I find myself needing to readjust in work flow. It’s no sweat, just a minor tick. Overall it’s gift for it’s price. Thank you.
