He showed me where I made my mistake. It’s a great app. The developer also recommended a book to improve my understanding of this method. The support developer is very responsive to questions. I recommended it to a friend. ———. Original negative review I just purchased this app. I cannot get past the intro page. The support site does not bring me to a way to contact the developer ### 5/5 — Great App *2013-08-12* I have to say what a wonderful tool that makes creating charts so much easier. I really appreciate the option to print, email or save the charts in iBooks. I am very impressed by the costumer service as well. When I had some little problems, Darren took care of it right away and explained to me what happened and with the new updates - just more tools. Great app - highly recommended ### 1/5 — App not working after upgrades *2013-07-31* Downloaded upgrade now app is not working. Tried making it work on all my iPads (2) and still didn't work. ### 5/5 — Polestar *2013-07-20* Fabulous program! Easy to use and the new update is great with all the info available in a click. Love how easy it to convert from natal chart to 10 or any year progressions. I highly recommend this program. ### 5/5 — It works great! *2013-03-20* This is a wonderful tool for generating ZiWei natal and progression charts. Straightforward and easy to use. It doesn't have a built-in library function, but it's easy to export named charts as PDFs to iBooks where I can maintain a client library. The developer is quick to respond to questions via the support page. ### 5/5 — Simple and versatile *2013-03-19* Great tool , very easy to enter data and change from Natal chart reading into progressions and email or print as I needed. Especially when I learned the option to save into iBooks ! Any time there has been a question Darren is very helpful and responds to requests immediately ! Contact him directly!!!!! Thank you! ### 3/5 — This does not work *2013-01-14* This does not work. It did not do my chart right. Tried to do another chart it showed the just same chart. Definitely a wast of money. Not worth a star but have to put one to post this review. ## Frequently asked questions about DYC Polestar ### What kind of astrology charts can DYC Polestar generate?
