  1. 5/5Solar System on the iphone

    I have used this app for six to seven years and two different iphone generations. It is a clock, orrery, teacher, astro app of the highest caliber. It is light weight and does not take a lot of memory, the A-R mode is handy to help confirm objects in the sky. There is no explanation of what is displayed, just factual data. Other apps can explain what one is looking at but that comes at a high price but if you have a basic knowledge of the sky than this is just awesome to behold. The ability to look in from space at your location and then switch the view so you are looking out from your location is just not found on other apps. I've been an amature astromner for 60+ years and other than looking up at the sky this app takes a strong position behind the actual sky.

  2. 5/5The best app ever

    As a keen observer of time and in particular the instances of solar and lunar eclipses across such thing as time, this app is perfect for my work and understanding the orientations of the solar system. I cannot express how deeply I appreciate the developer’s work. I am hoping to include some of their displays in my upcoming film about eclipses which they kindly have allowed me to do. Now I just need to get on with that work as I’ve been documenting these eclipse now for 25 years and as “my life’s work” it would be silly to abandon the journey here just at the end. If you haven’t already purchase this app do so immediately! It is a delight and obviously a labor of love which I completely understand.

  3. 5/5Might be the coolest App ever made

    I love this App so much!!! Hard to find the right words for why, but using it is quite meditative. I think it’s one of the best ways our knowledge and technology have been utilized in recent history. Of course nothing beats looking at the actual stars and planets if you have the opportunity, but this App gives such beautiful perspective and the amazing potential to reawaken interconnection. I don’t think most people contemplate the measurement of time and our place in the universe because there are so many distractions in modern life—but this gives me hope that staring down into a phone can actually enrich the way I look out and up into the rest of the world. Thank you for this App!

  4. 5/5Great Product

    I just started using the app. What would be nice is a manual that one could print instead of using the Share icon and selecting PRINT while viewing the instructions. Printing with Share messes up some of the pages due to the black filled headings. Maybe a night light capability if used in bedroom so it’s not so bright. Much easier to learn aspects if there was a formal manual. After going to cosmic-watch website on my laptop, I found the manual for printing as well as a quick start guide and tutorials. I take back my initial comment on manuals.

  5. 5/5Astrology Essential

    I been using this app for months now, almost on a daily basis. What could make it a little more efficient would be to add notifications for direct and retrograde motions. Other wise it’s been an essential to my study. Perhaps an update on the geocentric and topocentric toggle, when switching to geocentric then clicking realtime the sky gradient reappears and topocentric triggers. I find myself needing to readjust in work flow. It’s no sweat, just a minor tick. Overall it’s gift for it’s price. Thank you.
