7712 planets and counting.

The Exoplanet app is a highly visual and interactive catalogue of all known exoplanets (planets orbiting stars beyond our own Solar System). It is updated within hours whenever new discoveries are confirmed. An amazing model of the Milky Way lets you explore our universe all the way from the surface of the Earth to the Milky Way and the cosmic microwave background. The app has been developed and is maintained by a professional astronomer. And, it's free!

I had no idea
Exoplanet is like the ultimate reality check. Shows you just how small and insignificant we really are. Mind = blown! (February 18, 2014)
Awe inspiring
Very good app that has everything from information, zooming out into space and even size comparisons. Brilliant job on this wonderful app (February 13, 2014)
The most amazing thing ever
You have the whole milkyway galaxy at your finger tips, that is just insane :D (February 13, 2014)
This is the first app I've been inspired enough to review. This does a beautiful job conveying real, up to date scientific information at a variety of levels. It's beautifully done, and the radial velocity and transit animations are particularly impressive. I'm amazed at all the work that went into this, and it's free. (11 October 2010)
Well done!
Fascinating and well designed app. (10 October 2010)
Apps like this are what make the iThing great. A small app that gives you vast amounts of information on a subject most of us wouldn't normally bother to learn about. Getting push notifications when they discover a new planet is incredibly exciting. Seeing the total of known planets increase every time I open the app is surprisingly thrilling. This app connects you to those discoveries. It's made by an enthusiast, not a professional app developer, and you can see this enthusiasm in it. The presentation is excellent and constantly improving; the developer really makes an effort. The spinning globes are especially striking. In short, here's an app that shows why iPhones and the like are more than shiny toys; they can connect you to the wider universe and show you new wonders in an easy and intimate way. Thank you!
