Brilliant, real astrology software

This is the only software on the iPhone that draws authentic charts for astrological purposes. All the other so-called astrology software is either sun0sign astrology or ephemerides and orreries with a few extra features. This one is the real thing - astrologers, this is will draw proper charts for any location, with the ability to progress, return and show transits, even firdaria, plus it draws double-ring wheels - and this is only version 1! Can you imagine what follows? Kairon is actually a Mac astrology program and users of that will know the programmer knows his stuff down to traditional rulerships, so this will probably become a powerful tool. The Mac version is unconventional in its design, making features hard to find and use, and this appears to be a problem with the iPhone version as well which is why it only gets 4 stars. So: brilliant features, software design needs work to make accessible and intuitive, but if you're any ways serious about astrology this is a absolutely must must must buy.

Kairon is now basically useless

I used to LOVE this app. My last review was three stars only because they never updated it. Well, now they've overhauled everything. I lost all my saved charts because I have my apps set to automatically download. On top of that, it's SUPER glitchy. I've seen aspects that should say approaching listed as separating, unclickable links because they're mapped wrong (idk how to say this technically, but one link's space will overlap another link and you can't click the one you need because of said overlap), every time you click between the chart and aspects the orbs reset to a very high degree, the planets and points are listed in a weird order on the aspects chart, etc. I could go on and on about how disappointed I am in this because I seriously use to use this app and only this app. Now I have to find another one because this is the opposite of user-friendly.

Developer Response ,

Dear Euroflower, your data are not lost and you should have contacted support for a quick reply. Kairon has a data recovery option in share tab, that will allow you to reimport. Also the data can be saved to disk via iTunes.
There is also no general overlapping of clickable areas, but those areas close to the border are sometimes harder to click - a restart of the device once in a month can improve this behavior.
The catch with the aspects is: if the orbis is overlapping, i.e. if an orbis is so big that it includes another aspect, it can be that the wrong one of the two aspects is displayed but also with that orbis. It is best to use the orbis choker then you see. I will fix it, so that it will no more be possible, that aspects overlap, just for now the orbis choker is the fastest option.
Please contact support with questions and suggestions, as then you get replies within one day.
