"This is the best astronomy app for Android, period. Lots of customization options for charts, observing list support, and a big astronomical database make this the only Android app with enough depth to be useful for serious observing with binoculars or a telescope. Plus it can do everything the more casually oriented astro apps do, including a gorgeous view of the sky and the ability to hold your phone/tablet up to the sky and have it show you what you see. Worth the price."

- Mike Portuesi, December 2011

"I have used almost every astronomy app for Android that was available since I first got my trusty G1. Google SkyMap was our first "wow, neat!" astro-app. Others that required a donation just left me hanging. Currently, there are several sub-par ports of iOS programs. This blows them all out of the water. It's also the only one with telescope control via Bluetooth or WiFi... If you are SERIOUS about astronomy, SkySafari is it."

SkySafari for Android

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 Android, go to

As reviewed in Sky & Telescope magazine, SkySafari for iOS is "revolutionary" and a "game-changer" that can completely replace your desktop astronomy software. Now SkySafari is here for Android - and it will change the way you do astronomy!

Click any of the app icons below to purchase SkySafari from Google Play. SkySafari uses standard Google Play licensing. You can install it on as many Android Devices as you have linked to your Google Play account. SkySafari requires a Google Play account, and will not run on devices (like the Kindle Fire) which do not have Google Play access.

SkySafari - $2.99, 48 MB. 46K stars, no telescope control.

The basic version of SkySafari shows you 46,000 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 150 (or so) asteroids, comets, and satellites. It lets you find objects in the sky using your Android's built-in compass and accelerometer, and identify stars and planets by holding your phone up to them.

SkySafari Plus - $14.99, 197 MB, 2.5M stars, telescope control.

SkySafari 3 Plus adds a hugely expanded database, wireless telescope control - and the ability to leave Earth and orbit other objects in our solar system - to our basic version. It shows you 2.5 million stars, and 31,000 deep sky objects - including the entire NGC/IC catalog. It includes over 4,000 asteroids, comets, and satellites with updateable orbits. And it can point your GoTo or "Push-To" telescope anywhere in the sky, using your Android's built-in Wi-Fi or bluetooth, and our SkyFi or a bluetooth serial adapter.

SkySafari Pro - $39.99, 581 MB, 15M stars, telescope control.

The all-new SkySafari Pro has the largest database of any mobile astronomy app, period. It contains everything in SkySafari Plus - but also includes over 15.3 million stars from the Hubble Guide Star catalog, plus 740,000 galaxies down to 18th magnitude, and over 580,000 solar system objects, including every comet and asteroid ever discovered. It includes a new Moon map based on 2009 Lunar Reconnaissance Orbiter data, with 8x the resolution of any other SkySafari version. Yet it runs just as fast and smoothly as our $3 basic version.

All three versions of SkySafari require Android version 2.2 or later running on a 1 GHz or faster Android tablet or phone. SkySafari is optimized to use the full size of Android tablet screens, as well as smaller phone screens. Here are some examples:
