This is such a wonderful experience with heaps of beautiful images of Saturn and its moons. I love the clean, minimalist interface too, as it lets the beautiful imagery shine. Relaxing and informative. I recommended it. ### 1/5 — Latest update crashes =(( *2019-10-15, version 2.2.1* Really like(d) the app .. until the latest update: now the app won’t even open ### 4/5 — Good when working *2019-08-25, version 2.2.0* I have had this app for several years and it has been fine up until now. However, since the latest update it just crashes on opening. This problem appears to be solved by deleting the app then re installing it. Hope this is the solution! ### 5/5 — For Saturn lovers *2019-01-04, version 2.0.0* Outstanding high res photos with excellent educational text for each makes this app into a interactive book on the Saturnian system. Just get it. ### 5/5 — Fantastic Photos! *2017-10-13, version 2.0.0* This is the perfect app for space enthusiasts and armchair astronomers. These photos are wonderful, and I hope we get to see even more pics that were taken during this last year before Cassini plummeted into Saturn. ### 5/5 — Great app *2017-09-14, version 2.0.0* Good education for Saturn. Wondering if developers will update photos as spacecraft hurls towards the planet some time this week ### 5/5 — Like a Saturn encyclopedia *2016-04-19, version 2.0.0* Like a encyclopedia of Saturn and its moons ### 5/5 — Magnificent *2013-09-09, version 1.1.3* So full of amazing images, so beautiful, so informative, so worth the price ... The folks at JPL would love this app! This app is wonderful -- that is, full of wonder. I don't care who you are, get this app. You will be in awe of the stark and majestic beauty that is Saturn. If you weren't fascinated with astronomy before, this marvelous app has a strong chance of making you a dedicated amateur -- or professional -- astronomer. ### 5/5 — Wonderful pictures of the Saturnian system *2013-06-29, version 1.1.3* I almost overlooked this app for some of the fancier solar system explorations and planetary atlas apps... But I'm so glad I explored it! It's a beautifully presented app and it is really a no nonsense way to explore Saturn and its moons, with the fabulous Cassini pictures doing the talking. The original NASA info is available when needed, and the whole App is reminds me of the wonderful coffee table planet books I got as a kid. Inspiring stuff! ### 5/5 — Sonda Cassini *2013-05-25, version 1.1.3* Las imágenes son sencillamente, FANTÁSTICAS !!!!!! ## Frequently asked questions about Cassini HD ### What is Cassini HD?
