Sky Guide: View Stars Night or Day Reference App Review (iOS, $1.99)


Languages: English, German

Seller: Fifth Star Labs LLC

• Time-lapse has arrived! Swipe UP from the bottom edge to reveal new time controls. See satellites streak through the sky at 1,000X real-time. Turn it up to 30,000X to see beautiful, spinning star trails.* Go even faster to switch into day-stepping mode and you'll see the motions of the planets as they dance around the Sun. Use the date & time picker to witness past or future events.

• 64 bit support. Compatible with iPhone 5s, iPad Air, and iPad Mini with Retina display.

• Realistic comets. We not only gave Comet ISON some company with the likes of Comet Hale-Bopp, Halley and more, but also accurately stylized them with beautifully dynamic coma and tails. Pro tip: use the new time controls to see comets evolve as they approach the Sun, or witness magnificent comets of the past!

• More deep sky goodies. We've DOUBLED the number of photographic articles for galaxies, nebulae and star clusters. Those who keep exploring will be rewarded.

• Improved Search: we made it easier to find things you might be looking for.

• Satellites: flyovers at night that are obscured by Earth's shadow are no longer listed in the article view.

• Added a location for the North Pole (listed under Geographic Points). The sky looks different here, especially in time-lapse mode!

• Various UI improvements

* Star trails are supported on devices running OpenGL ES 3.0 (iPhone 5s, iPad Air, iPad Mini w/ Retina display)

A star and constellation guide has never been more beautiful and easy to use. Just hold it to the sky to automatically find stars, constellations, planets, satellites and more. It’s stargazing fun for all ages and experience levels!

*****App Store Best of 2013*****

"If you want to learn more about the stars, planets, and satellites spinning around us at all times of the day, Sky Guide is the best app to do it with."

“An experience like no other on iOS...10/10."
–App Storm

“Until now, the best [astronomy apps] have emphasized utility over beauty. That all changes with Sky Guide.”
–Mac Life

Is it a star or Saturn? Learning what’s in your night sky is now effortless with Sky Guide. Hold your iPhone or iPad up and Sky Guide automatically aligns itself to the stars above you–no setup required!

Whether you’re looking for the constellation Virgo, the Andromeda Galaxy or Mars, Sky Guide will satisfy your curiosity. You can search for thousands of celestial sights—and be guided exactly where to see them in the sky above you. Just follow the arrow.

Want to watch a satellite pass overhead? Sky Guide features hundreds of visible satellites for you to track. See them rise and chart their paths as they fly through space. We also offer an add-on pack that provides satellite identification, detailed historical information and future flyover times.

Voyage to the past or future with cinematic time controls. Know where the Moon will be later in the evening so you can capture that perfect photo. Or, witness the approach of magnificent comets and see their tails evolve as they fly around the Sun.

Sky Guide contains immersive visuals unlike any star app you have seen before. With exclusive, high-resolution photographs captured by one of the app developers, you’ll witness millions of stars—not just a few thousand simulated points! Plus, you can control the intensity of star light with HDR brightness gestures to dial in your local viewing conditions.

Sky Guide may have few buttons but it has ample content. With richly illustrated and cross-linked articles—many by leading astronomical authors—countless enlightened moments await novice and seasoned stargazers alike.

Plus, Sky Guide functions with or without a Wi-Fi, data, or GPS signal. Take it camping or use it overseas. Everything is at your fingertips at all times, in all places.


• Elegant and simple: Unobtrusive controls and gestures free up the screen for the best sky view yet.
• Rich content: Generous amounts of stunning graphics and original artwork.
• Soundscape: Designed by Mat Jarvis, the most featured composer in the award-winning soundtrack for the game Osmos. Stars have sounds based on their temperature and size.
• Useful anywhere: Works with or without a GPS or data signal. Built-in access to hundreds of articles no matter where you are.
• Time controls: Know where objects will appear in the future with cinematic time-lapse effects.
• HDR brightness gestures: Dynamically control how bright the sky is to match how many stars you can see under light-polluted skies.
• Red night mode: Preserve your dark-adapted eyesight.

Please note: Sky Guide requires a gyroscope, so it doesn't work with iPad 1 or iPhone 3GS and earlier.

  • Loving Astronomy with this application

    by loving series

    This is one of my favorite applications for Astronomy! It is so detailed, and shows the stars currently overhead, wherever I may be. It also labels the stars, and constellations as well as nearby planets, in detail.

  • Creative and well done

    by St*rgazer

    Amazingly beautiful. You will fall in love with this app.

  • Great Star App

    by Cussawaga

    Easy to use. Grab it to identify that one star or object in the sky, or spend hours exploring the heavens. Lots of fun!

  • Superb App, Outstanding Support

    by AmberCrystal

    I love this app. I have several other star guides, but this one stands out in a few ways. The interface design and user experience are top notch. Plus, I *really* like the ability to adjust the perceived darkness of the sky. This provides for a much easier to use and more accurate display when viewing the sky from a light-polluted area. The add-on Satellites Pack is well worth it and adds an extra dimension to looking up at the sky. Recently, I ran into a strange issue with the Satellites Pack that caused the position of the ISS to be improperly reported. It turned out to be a power outage of one of the data providers (winter storms…). While tracking this down, I received quick, thorough and personal replies. Great support is always appreciated.

  • Amazing!!

    by WhtFlnt

    So education!! A must have for star gazers!!

  • Fantastic astronomy app

    by brild

    All my stars

  • Absolutely wonderful.

    by fergy13

    If you have even a passing interest in the night sky, get this app! It is a great way to learn about constellations, satellite paths, and planet positions. I've been using it with my children and they are now able to recognize a few constellations without the guide. This is a stunningly awesome app that I've been telling all my friends and family about. Don't hesitate!

  • Incredible!!!

    by Bring 'Em Back

    I was just recently in PR, up in the mountains, where the stars just filled the night sky. I wanted an app for my iPad that would help me identify the constellations, galaxies, etc. and came across Sky Guide. Let me tell you, this is a must have app! I showed it to my parents and they too were blown away! It is a steal for $1.99! Get the app and you will never put it down. Great teaching tool as well.

  • Useful. Educational and fun.

  • Brilliant

    by Aluminum Nate

    The depth of knowledge available through this app is staggering. Great interface and a beautiful experience. If you are a casual astronomer or just want to see the sky in a new way, this is a must.

  • Planetarium Information Quality

    by CO_Native

    This app is amazing and is like being in a planetarium. Having the animated overlay makes constellations in the night sky stand out, additional information tabs about the constellations and their respective mythology is truly informational, and the ability to "point and shoot" at the night sky makes it fun for kids. A brilliantly designed app!

  • Excellent

  • This sky guide is the best

    by Jfink30

    This app is definitely worth the $.99 and the in app $1.99 add on. I learned more in 15 minutes on this app then I ever did in high school. I would absolutely recommend this to everyone that is interested in learning about the stars and satellites humans have in the sky.

  • Great App for beginners

    by clifford poe

    I love this app. It has a gorgeous display, great sound and it records your coordinates and shows the sky from your perspective related to your geographical location....

  • Top ten apps out there

    by Imthejuan

    This app is amazing for people having curiosity about space and galaxy. This is definitely one of the best apps to try and the fact that it gives you even more info on any star you choose is so much worth the .99 you pay for. Design 5/5 Quality 5/5 Longevity 4/5 Money's worth 5/5

  • Education, fun for everybody!!

  • Amazing app... But

    by Tleggs15

    I absolutely love this app and all the features. But it would be 100% perfect if you could get a reminder every time a planet or star or whatever it is rising so that you can see it. I've been trying to catch Venus for ever now and I always forget to look!! So please add this feature!! Thanks

  • Unreal app

    by MadGamerFace

    Very Useful App. Use It Almost Everyday.

  • Freakin' awesome!

    by House hunting hobbyist

    Being able to point a mobile device in any direction to see stars and celestial bodies in their positions in any point within linear time has always fascinated me - but this app is also has intensely beautiful imagery. I love being able not only to stargaze for hours but to also track satellites and read about what's floating around up there in outer space (I have not yet located Gene Roddenbury but I'm still looking)

  • Fabulous!

    by Paul Frick

    Love the interface. Easy to use, yet has depth.

  • Perfect app!

    by Ashcanzzzz

  • Well done app

    by Cjburns77

    Really like it

  • Best $2 you'll spend on an astronomy app

    by Draftymeadows

    Simply said, it's great. Of all the star apps I tried, this is the best. It's the one I use most. It is my go to app. The imagery is incredible. Get it without regret!

  • Star Guide

    by Mark The Rater

    Living in one of the cloudiest cities in the world I really appreciate using sky guide. On the rare chance we have a clear sky I can't wait to see some of the things I've been looking at on my sky guide.

  • Excellent app

    by SeoulSister1

    Excellent app

  • Good

    by rtcompsvcs

    Interesting app. Worked on both iPad and iPhone pretty good

  • Why digital devices matter

    by Snallygaster

    Simply beautiful, inspiring, educational awesomeness. All you complaining young'uns have no idea the power of what's at your fingertips. Be amazed every day.

  • Good;)

    by Dkfma

    I like it

  • Coolest app to see the stars

    by 685millie

    I recommend this app to all my friends. You can choose to see pattern lines or constellation images for visualization and learning. Works via GPS I believe. So, you can point it to the ground and see the sky on the other side of the globe? Cool.

  • Wanna know what's up there??

    by Zuno72

    Really cool app....the info on stars, planets, constellations and satellites take it over the top!! VERY easy to use, just hold your phone up and enjoy!

  • Not What I Expected

    by Fireeflyy620

    I thought this app was to show you the constellations in the sky when you point your phone to the sky outside. But it shows you the starry night sky on the phone and wherever you move it, inside or outside. It wasn't what I was looking for.

  • good

    by every88


  • Perfect!!

    by ItsChristianHansen

    I've only had this app for a day now but it is easily the best of its kind. Visually, the app is amazing. The imaging is the first thing I noticed and they did such an amazing job with it. The controls are very intuitive and just make using the app very friendly and clean. This app is a must-have!
