Updated and Slowly Relearning

-- I stand corrected the app does not require location 'services' turned on. The app was also easier to wield after time with it, but still haven't been able to find most my old data and transfer it. Pretty much all of the data that did cross over from the older version came without their original names.

It'd be nice to be able to choose the classic version, but worth mentioning again the developers are responsive and appear to care about the quality of their work; with that my rating increases again -> 3.5 stars.

Developer Response ,

This update does not require your location services turned on, the Atlas is still integrated. Also your previous charts are not lost unless you explicitly delete the app - they are available via iTunes and can be saved to disk. If you select the sharing tab of the navigation and take the bottom entry of the sub-navigation, you can start a new recovery, as the recovery function was improved in the first few versions to make up for the original failure of version 2.0. If still some cities should not get important, please email me such a chart to support, so that i can analyze the cause. All my charts got imported in the end.

Montreal missing in atlas

iKarion is missing a major city in its atlas, i.e., Montreal, Quebec, Canada. It was in the previous version but, since the last update, it has vaporized! Please replace.

Developer Response ,

Montréal is not missing, has never been missing, it is just listed a bit deeper down, if you type "Montr" and if you type "Montré" it is already on position 2. In the settings you can define, how to search for cities, there are different approaches: You can search by cities in an exact and in a less exact way but can also have them listed by countries. Best try which is more convenient to you.
You are always welcome with questions, but for answers in time please contact support - then you get a reply within a day or two.

Perfect birth chart generator!

This is a fantastic app. You can choose exactly what planets/objects will be shown on the chart (via Settings) and the chart is beautiful and very easy to read. Lets you generate charts for your chosen date/time/place. Highly recommend it!
