Atlanta, thanks for the input! Does it include any satellite information? Or, bright star or Messier rising and setting -- or, better transiting the meridian?
SN74, you raise a good question! I wouldn't expect to use the full-blown Sky Safari on the watch.
However, I can think of several benefits of astronomy apps on the watch. I often don't have my phone with me -- but might be wearing the watch. When I do have my phone with me, it's typically off and in a pocket with keys, pens, comb, etc. A nuisance to fish out. Hence, the watch could provide:
1. A quick way of seeing sunrise, sunset times.
2. A quick way of checking on the phase of the Moon.
3. Not having to putter with the iPhone in the dark. Or, drop it!
4. Bringing up Messier info at a glance.
5. Fast access to ClearSky Clock.
5. Quick check of ISS and Hubble flybys.
6. Spot check on what that bright star or planet is -- or, in the middle of the night, which constellation I'm seeing.
I'm sure there are plenty of other uses I've not thought of, but an app developer has! Hence the question.
I used to have a small Nokia flip phone and used a wonderful planetarium app with it. Its screen wasn't that much bigger than the Apple Watch, but it was a treat to use.
Luminos has a version of its app for the Watch and it has some pretty spiffy features. See
So, partly wondering how Sky Safari's Watch support compared.
Would I use the watch for star hopping at a scope? Probably not! But for getting some quick astro info, it could be useful.
