Brilliant app, my go to guide to the sky. However, I would like to report a bug with the calendar to change the date in the app. When I try to scroll up (back) the days of the month, it doesn't let me go to the previous month and it gets stuck at the 1st of the month. Also, the previous month to tbe one that you're in has an extra day, such as 32 days in January. It only seems to affect some years, such as 1980 and 81 and January 1965.

I've been on and off this app for a few years, but it's the best I've found for general astronomy. The upgrades are expensive, so it might be worth it to go for the full app once you see you like the free version. The older version used to let you jump from sky view right to exploratory mode, and you can't get the Latin names for constellations any more, which is how I know most of them. Still, I've shown plenty of friends the star chart, and it helps everyone understand.

For people who are trying to grasp the universe and all it contains (or beyond), this is fantastic! I can't afford to pay for upgrades, so I'm on the basic level. However, there is so much information they give for free, that you'll learn far more than you realise. By tweaking settings, you'll learn to recognise different components of the night sky, easily find how they look as we move around them, & explore the heavens even on cloudy nights. I highly recommend it. And no ads. Brilliant!
