With the Wolfram Stars Reference App, you'll have access to real-time data on over 100,000 stars. Compute your favorite star's sky position, find out when it will rise next, and perform advanced calculations. - For easy browsing, stars are sorted into groups such as the Northern or Southern Sky Stars; Brightest Stars; Nearest Stars; and Giant, Supergiant, and Main Sequence Stars - The Star Lookup allows you to enter any star name in the input field - Examine and compare properties for each star, such as its magnitude, spectral class, temperature, mass, lifetime, and distance from Earth - See the star's position on the Hertzsprung–Russell diagram - Compute the star's current sky position from your location, find out whether it is visible, and learn the times of the star's next rise and set - Perform advanced astronomical calculations using the Stefan–Boltzmann law, Wien's displacement law, blackbody luminosity, and mass-luminosity relationship The Wolfram Stars Reference App is powered by the Wolfram|Alpha computational knowledge engine and is created by Wolfram Research, makers of Mathematica—the world's leading software system for mathematical research and education. The Wolfram Stars Reference App draws on the computational power of Wolfram|Alpha's supercomputers over a 3G, 4G, or Wi-Fi connection. ## Key features - Real-time data for 100,000+ stars - Star grouping and lookup - Detailed star property examination - Hertzsprung–Russell diagram visualization - Sky position and visibility computation - Advanced astronomical calculations ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/wolfram-stars-reference-app/id489840510/reviews.md ### 5/5 — Phenomenal Reference App. For Astronomy Students *2013-07-28, version 1.0.0* As mentioned in the title, this application is one of many fine applications that the WolframAlpha team has been so generous to bestow upon us here in the app. store. My only gripe with the program is the lack of comparability with the iPhone 5 in regards to taking advantage of all of the screen real-estate the 5 has to offer. I know it doesn't take much tweaking to scale the application appropriately, so it would be very much appreciated if it would be done sooner rather than later. Thanks again for a great app!! - Sincerely ### 2/5 — Very limited functionality. Not worth the money *2013-03-23* Essentially this app just displays some very basic data about a few dozen stars, essentially nothing that couldn't be searched for on Wikipedia. The 'computation' section allows for some simple data comparisons between a few stars, nothing particularly useful, even if it is briefly interesting. All of this can be achieved with Wolfram Alpha in a browser. This app has very limited capabilities and is not worth the money at all. ### 5/5 — Awesome *2012-03-20, version 1.0.0* I just use it to find out where stars are where I am, but it has a lot of other features too. ## Frequently asked questions about Wolfram Stars Reference App ### What kind of star data does Wolfram Stars Reference App provide?
