Study thousands of stars, comets, and satellites with Fifth Star Labs’ stunningly gorgeous astronomy app. Using a built-in compass, Sky Guide lets you easily locate constellations and other celestial bodies—or you can simply hold up your device and learn more about what’s in front of you via dramatic photos and detailed descriptions. A stirring soundtrack and a time-lapse feature that shows where the moon and other objects will be later make your stargazing experience even more enchanting.
The Universe is a Wanderous Place
It is probably best to describe this anecdotally:
I just watched PBS's new 2-hour special on the Voyager 1 and 2 spacecraft. It began giving me a sense of this grand scale of a solar system we live in... a perception only reinvigorated few times through the words of someone like Carl Sagan describing the Pale Blue Dot. I looked at my phone and immediately opened this app again to just look at space. As I wondered to my back door I realized that I was fortunate enough to be waking outside into a cloudless night. I turned on night view mode, turned down my display brightness, and let the ambient music of this app play. I was alone, along with the living silence of night with the smooth, soothing music playing on the app. I looked up with my phone, navigating amongst the constellations, in awe at how the sight could be so beautiful, seemingly unique every time, and so often taken for granted. Realizing the opportunity, I searched for satellites via the app and eagerly moved my phone around the sky to track the paths of Coos Rockets that were flying by and anticipating the next flyover from our man-made moons. As much as I adore the night sky in all its grand beauty, this app makes exploration even more satisfying, concise, and exploratory than I otherwise would have been able to do. Thank you.
Love it, but confused after updates
Had this app for a while and still my favorite. However, I’m confused about the updates. There was a recent update that added Chiron, for example, but it is not listed under the “recently added” section. Additionally, even when I look for it manually, it just points to where the object is, but there is no image associated with the description, nor can you zoom into it. At the same time, other recently added items, such as RS Puppis, has the image and location, but no description (you have to tap on the image of the star within the image - like a star within a star - to get a separate description). Doesn’t seem like the recently added section is working properly within the app. Is it just not updating correctly or am I missing something???
Also, since very recent updates, the star brightness feature that requires 2 fingers to adjust directly on the screen is so overly sensitive that I am constantly having to adjust the brightness as I navigate the sky map. Very very frustrating. Is there no way to lock that feature or disable it?
Otherwise, still amazing.
Developer Response ,
Thanks for the feedback. We goofed on forgetting to add Chiron to 'Recently added'. Sorry about that. Also, we made some changes to the way sky brightness works so it is helpful to know that is being too sensitive for your usage. We'll try making some refinements to that.
