Note: If you are running Android 4.0 or higher, look for our new SkySafari 4 Plus App.

As just reviewed in Sky & Telescope magazine, the iOS version of SkySafari is "revolutionary" and a "game-changer". Now here for Android, SkySafari will change the way you do astronomy!

SkySafari Plus adds a hugely expanded database, wireless telescope control, the ability to fly into orbit around other planets our Solar System, and beyond it to other stars in our Milky Way galaxy, to our basic version.

Make sure you have at least 600 MB of free space on your internal SD card for SkySafari Plus to download this database from Google Play the first time it runs! (Note: due to Google Play rules, this data cannot be moved to your external SD card - you must have 600 MB free on your internal SD card!)

SkySafari Plus shows you 2.5 million stars, and 31,000 deep sky objects - including the entire NGC/IC catalog. It shows the Solar System's major planets and moons using NASA spacecraft imagery, and includes over 4,000 asteroids, comets, and satellites with updateable orbits. It can point your GoTo or "Push-To" telescope anywhere in the sky, using your Android device's built-in bluetooth or WiFi, and our SkyFi wireless or Starry Night BlueStar bluetooth serial adapter.

Please Note: there is no upgrade pricing from SkySafari Plus to Pro. Make to get the version you want!

SkySafari accurately shows you the sky from any place on Earth, at any time up to 10,000 years in the past or future. It includes 1100 encyclopedic descriptions of the constellations, stars, and planets written by professional astronomers. And it contains over 800 images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.

If you have an Android device with a compass, SkySafari Plus can help you identify stars and planets by holding your phone next to them. Tap the Compass button (or tilt your phone up toward the sky) to activate the compass. Now, as you move the phone around, the sky chart follows your motion. Search for any object in the sky, and follow the arrow on screen to find it!

SkySafari has a "Night" button to preserve your dark adaptation as you're exploring the night sky. The Time Flow feature lets you animate the night sky using simple VCR controls - follow the motion of the stars and planets as SkySafari compresses days, months, and years into a few seconds.

SkySafari's streamlined user interface puts the universe at your fingertips - and turns your Android device into a 21st-century telescope controller. SkySafari is your celestial travel guide!

SkySafari Plus includes 250 times more stars than Google SkyMap. Our deep sky database contains thousands of NGC/IC objects, not just the 110-object Messier catalog.

Our apps contain hundreds of built-in images, and thousands of object descriptions, written by professional astronomers. Other apps give you Wikipedia links - which don't do much good out in the field, away from Wi-Fi or data network connections.

Our Plus and Pro versions can control telescopes. Other apps can't reproduce basic astronomical phenomena like lunar eclipses and Jovian satellite shadow transits. Our apps were developed by passionate astronomers with a penchant for quality and accuracy - we make a living from our products!

    Paid 14 bucks for this app. They stop development and release sky safari 4 and expect me to pay for essentially the same app agian. Bad way of doing business.

    My books rarely come out since I got this app. Amazingly complete and accurate. Love the ability to zoom in or out to match view to my telescope eyepiece or my binocular view.

    Excellent app. Hangs now and then, but that's not a problem as it gives reliable and valid results. Accept nothing less!

    I really like this app for its many features! It is the best astronomy app I have seen so far. I just want to list some features I wish it had. A way to lock the selected star or sky object so another is not inadvertently selected. The ability to set th
