Reviews

"There is so much here, it is hard to know where to begin... right now SkySafari 4 is the top astronomy program of dozens of offerings by a wide margin."

- Mel Martin, TUAW, December 2013

"SkySafari 3 stands out among consumer-level iPad planetarium apps for the variety of objects it shows and the thoroughness of the information it provides for each object. Its sky depictions are both pleasing and accurate. Whether you want to learn the constellations, spot satellites, or view star clusters, galaxies, comets, and asteroids with binoculars or a small telescope, the well-rounded SkySafari 3 and an iPad is all you need to get started.."

- Tony Hoffman, PC Magazine, November 2013

"Southern Stars has outdone themselves this time! The newest version of SkySafari maintains the features that made it the best in class of the astronomy apps out there, and added more details and features that their customers wanted, including requests made by amateur astronomers such as myself... There is nothing else like it on the App Store."

- Jason Creager, December 2013

"It's virtually impossible to adequately discuss this app in one small review because there is just TOO much to say about it. Suffice it to say that this was already the best astro app out there and it's now even better."

- Mark Maxwell, December 2013

"Smart-phone and tablet-based planetarium programs are game changers... Many of these programs behave similarly and have comparable features, but Southern Stars' Sky Safari 3 stands out for its pedigree... The Pro version of Sky Safari 3 has completely replaced my desktop planetarium program. Before now, we could only watch the sky on computer screens. With SkySafari 3 we can touch the sky, and that's revolutionary."

- Joe Heafner, Sky & Telescope, December 2011

SkySafari 4 - for iPhone, iPad, and iPod touch

Please Note: SkySafari is now owned and supported by Simulation Curriculum Corporation. This page contains legacy information for owners of older versions of the app. For the latest information on SkySafari for iOS, go to www.skysafariastronomy.com.

According to The Mac Observer, SkySafari 3 was "the best of all the star chart apps for iOS". As reviewed in Sky & Telescope magazine, SkySafari is "revolutionary", and a "game-changer" that can completely replace your desktop astronomy software. Gizmodo says: "Of all the stargazing and astronomy apps available for iOS, SkySafari 3 is the best."

SkySafari 4 - $2.99, 78 MB. 120K stars, no telescope control, view from Earth.

The basic version of SkySafari 4 shows you 119,000 stars, plus 220 of the best-known star clusters, nebulae, and galaxies in the sky. It displays the Solar System's major planets and moons using NASA spacecraft imagery, and includes the best-known 500 (or so) asteroids, comets, and satellites. It accurately shows you the sky from anywhere on Earth, at any time up to 100 years in the past or future, and lets you identify stars, planets, and constellations with your iDevice's GPS, compass and/or gyroscope.

SkySafari 4 Plus - $14.99, 241 MB, 2.6M stars, telescope control, view from Solar System.

SkySafari 4 Plus adds a hugely expanded database, wired or wireless telescope control, and the ability to leave Earth and fly into orbit around any Solar System object or nearby star - to our basic version. It shows you 2.6 million stars, and 31,000 deep sky objects - including the entire NGC/IC catalog. It includes nearly 18,000 asteroids, comets, and satellites with updateable orbits. And it can point your GoTo or "Push-To" telescope anywhere in the sky, using your iPhone/iPad/iPod's built-in WiFi, and our SkyFi or SkyWire serial accessories (sold separately).

SkySafari 4 Pro - $39.99, 945 MB, 27M stars, telescope control, view from Solar System or Nearby Stars.

The all-new SkySafari 4 Pro has the largest database of any astronomy app, period. It contains everything in SkySafari 4 Plus - but also includes over 27 million stars from the Hubble Guide Star catalog generation 1 and 2, plus 740,000 galaxies down to 18th magnitude, over 620,000 solar system objects - including every comet and asteroid ever discovered - and a Moon map based on NASA's latest LRO data with 8x the resolution of any other SkySafari version. It shows you the sky with sub-arcsecond precision from anywhere on Earth, in the Solar System, or beyond, at any time up to one million years in the past or future - yet it runs just as fast and smoothly as our $3 basic version.

All three versions of SkySafari are "universal" apps for iPhone, iPad, and iPod Touch. All three require iOS 7.0 or later.
