Here's the section on astronomy apps from my post (#22) at https://www.cloudyni...mers/?p=5184287

 

Some of the free planetarium apps that I use include Celestron's SkyPortal, Star Chart, and Star Walk.

A number of other surprisingly good free astronomy apps - https://www.hongkiat...targazing-apps/ and https://ioshacker.co...onomy-apps-2017 - are also available. 
 

Other astronomy apps are discussed in the article at https://www.iphonene...ons-for-iphone/

Sky and Telescope has a nice set of interactive web based tools. I use them from a Chromebook.

I use Sky Safari on an iPhone X. It works very well.

I like Night Sky, it's nice because it's AR and you can move you phone around the sky and see what's available for viewing.

I hate calling software for PC an "app" (guess I'm old school) and I don't do Apple, so this is Android only:

 

I definitely second Daff Moon already mentioned above, there's much more to this app than you might think at first!

 

Also:

Moon Atlas 3D (sometimes a little buggy but great to find your way around the moon)

Skywiki (mostly for news, also includes a decent compass - the periscope and sky chart features are not as good as Daff Moon's)

Stellarium (though the ads are a pain) Note that the Desktop version (Linux/PC/Mac) is free as in free beer. There's also a pretty good web-only version - no installation necessary, just click and use. I don't think the paid version is worth it, SkySafari is waaaay more powerful.

SkySafari (actually I never used the free version. The paid version is maybe the best bang for the buck you'll ever spend on astronomy software!)

Clear Outside

Nightshift

 

I do NOT recommend:

Good To Stargaze (the free version is almost unusable and IMO the paid version is too pricey for something that Clear Outside does for free)

Light Pollution Map (free version is pretty useless; the website is better, see below)

Star Chart AR (thought it would be interesting at first, but really it's just silly)

Star Walk 2 Free (too cartoonish for my taste, and the nag screens are pervasive)

 

SkEye is definitely an interesting concept, but in the end it did not work that well for me (and I stopped using it once I got a GoTo mount). Still, you may want to give it a try.

 

Finally some websites: https://astronomy.tools is an outstandingly useful website. So is https://www.lightpollutionmap.info.

SkySafari + is what I use to plan, observe, and document with. The + version has more objects in the database and also has observing lists you can download from a repository.

Take a look at my free “Our Galaxy” app.  Great for learning about our galaxy and the locations of deep sky objects within and around it.

Absolutely wonderful app! I really enjoy learning about where things are in 3D and about the structure of our galaxy!

 

Thank you SO MUCH for making it available.

Thanks.  Please spread the word.  I’d also appreciate your leaving a review/rating on the appropriate app store.

Astrospheric is a fairly good weather predicting app for astronomy.

Kstars for computers. It does almost everything.

Don't bother with the mobile version of it, though.

Free is good, but the astro apps are so reasonably priced, a pittance in most cases, that it's worth supporting developers!

 

In any case, among the freebies, APOD, SOHO, Exoplanet, GOISSWatch, Planets, Moon, Moon Globe, Gas Giants, Moon Calendar, Sputnik!, etc.  The last couple may have cost a couple of bucks — it's been so long since I got them, I don't recall whether they were originally free or not.

 

Another good free app is Apple's reader app — iBooks now known as Books — as you can download all sorts of free 19th and early 20th century astronomy histories and observing guides.  Lots of good stuff!

Thanks for my morning laugh!  We were using apps on PC's long before smart phones were even a glimmer in someone's eye.

 

Regarding the question in the title, here are some suggestions off the top of my head.  Most of the previous suggestions appear to be oriented around planetarium software, but I'll take a slightly different approach.

 

ASTAP, for plate solving.

PHD2, for guiding.

NINA, a very full featured app for automated imaging.
