This APP is truly amazing. At 67 years old I have never really looked up until the pandemic has given me time to do so. I luckily just stumbled across this APP and instantly was amazed at how much is out there, how much I’ve missed all my life and how wonderful the cosmos is. I’ve found the APP simple to use. I live in town with too many city lights so I’ve focused only on stars and planets visible to the eye, the 20 brightest and found the basic information to be fascinating. The he APP tells the details such as size, distance, makeup, life span and how the object has been viewed in human history. The only flaw I experience each day is the compass. Very frequently I find the APP to be many degrees, sometimes even 180 off. Makes identifying objects difficult. I don’t know if that is due to my iPhones internal compass being off or if the APP has its own compass, but it does require recalibrating the compass by spinning it around in circles or sometimes shutting the phone down. It would be nice to know how to eliminate this issue. But, for the money, are you kidding, this APP is so amazing it’s truly incredible. Thank you to the developer!

Great app, but some improvements are needed

After doing some research on astronomy apps, I read that SkySafari was the best. I don’t usually purchase apps, but I decided to give it a try. Overall it’s an excellent app. I only have a few problems with it. Although it’s highly configurable, it only supports notifications for ALL planet risings (and “bright satellites and flares”), rather than letting you choose the planets you care about. (I don’t care much about Pluto rising.) Also, the app offers a “Do not disturb between” option for the notifications which allows you to enter a From and To time, but when I enter times and exit the settings and then return, the times are not saved. Maybe that’s a bug, or maybe I’m doing something wrong. I’d also like to see an option to display RA/DEC coordinates on the main screen. Unless I missed it, it appears to only support the display of AZ coordinates there. I use another astronomy app that provides a TelRad bullseye at the center of the screen, with associated coordinates (either RA/DEC or AZ). I know SkySafari provides all that information, but it seems that other apps do it slightly better. Overall, I still think SkySafari is a great app. (I’m not an experienced astronomer, so this is a beginner’s opinion.)

Too much unclear

Looks like a good app, and I was trying to decide whether to upgrade to Plus while the discount was available (or possibly even Pro)—but there are Help files that are unclear, graphic glitches with the Apollo addition, and the voice control (though I understand it’s in “progress”) doesn’t work even with the example commands listed.

It’s less than clear what new features are available in the upgrade version, other than the free Apollo add-in—which I already purchased. So I don’t have enough reason (at least not enough clear reason) to upgrade, especially when I’m having trouble with features already available.

I’ll definitely keep the app on my phone and use it. Perhaps it’s just me; but, regardless, if I’m already having trouble, there’s little point inviting more. All the basic features seem to work fine, and I’d still recommend the basic app for others—perhaps those who might have better luck (or even sufficient skill) to use it more effectively.
