Seriously — you can’t turn off the very annoying sound effects? This is a complete deal breaker. What are you thinking, developers? Otherwise this is a really cool thing, but I am stunned that you have to listen to this clicking and whooshing new-agey soundtrack. Developers, PLEASE remove this feature! I will have to disable the app. Bummer.EDIT — I’m an idiot. Preferences are available in the toolbar at the top of the screen. Sound is off now. Sorry, and thank you!

This app worked perfectly for roughly two days. The app froze up and when I restarted it I realized that the entire top half and the bottom right quarter of the screen was frozen and the bottom left quarter displayed part of the spinning solar system that was not connected to the other three quarters of the screen. To simplify that, the only part of the screen wsith a spinning solar system is the bottom left quarter of the screen. I have tried changing multiple settings, deleted and re-downloaded the app multiple times, and sent several emails to their app support email but have recieved no reply. I waited a full week for a reply but after silence from the app creators I decided to try this platform prior to giving up. If you contact me with a solution I will change my 1 star raiting back to a 5. If you continue to ignore me, the raitimng will remain at 1 star. Thank you.

I'm middle school science teacher and absolutely love this app. Not only can I teach the planets with some basic information, but I can also talk about and show the lunar cycle! I would like an option under preferences where I can disable the camera movement. Every mouse click changes the angle, which isn't a big deal, but having the ability to disable would be fantastic.Great overall app. Well-made and authors should consider creating science apps for multiple areas: plate tectonics, such as, plate movement, boundary interactions; creating atoms with subatomic particles; so much more you all can do.Thanks for this, from an astronomy-lovin' nerd.**NOTE** to the previous reviewer, and as mentioned by others previously, the circle in your menu bar at the top is the options menu for the app. Again, as another said, the black donut. Hope this helps, it sure helped me.Also, if your animation stops and your using macbook, make sure you're plugged in or that you haven't selected "disable the animation when battery is in use".

This app delivers exactly what it promises, a beautifully rendered moving model of the solar system for your Mac desktop. The planets swing along their orbits in a mesmerizing celestial dance, while moons and asteroids move through their own orbits (if you choose). Makes for the perfect live wallpaper for the astronomically minded and a great teaching aid for kids. A nice range of preferences is offered, while set up and changes are simple. Looks fantastic on my 27” iMac. Kudos to the developer. This app is well worth the tiny price. Highly, highly recommended.
