Cast by ? Comment mettre son nom ?

Comment mettre le nom de l’astrologue par défaut, il marque « Cast by iPhone ». Mais je ne vois pas comment régler le nom, c’est-à-dire remplacer iPhone par mon nom.

Suite à votre réponse j’ai fait ce que vous m’avez proposé mais rien n’y fait. Le nom « iPhone » n’est pas modifié !…

Bonjour, Le nom peut être modifié dans les réglages de votre iPhone : **Réglages → Général → Informations → Nom** Vous pouvez y remplacer « iPhone » par votre propre nom. Bien cordialement, Kilian

Love this program!

I absolutely love this program! However, right now, I cannot edit my list of people, clicking the edit button to add a new group or chart closes the program completely. I’d really love for this to be fixed! Also, the floating sidebar is a teensy bit annoying. Is there a way to have it optional as floating or fixed? Keep up the great work!

Sehr gute Unterstützung in der Beratung

Gutes Programm, es gibt wirklich nichts besseres um schnell mit Klienten arbeiten zu können. Daher 5 Sterne, wenngleich ich mir sehr wünschen würde, das Standard iOS Dialoge implementiert würden. Die aktuelle Methode ist kompliziert und wirkt veraltet hausbacken. Dabei sind die Standard-Dialoge doch in der Entwicklungsumgebung schon vorgefertigt vorhanden.

素晴らしい！のですが…

ビュー表示にした時、チャートに文字が掛かる場合がある。フォントサイズが選べるとよいですね。

場所の指定もバグなのか地図でポイントを指すしかないようで現状不便。出来るのであれば日本での住所検索の正しいやり方を公開して欲しい。

オーブを天体別に指定できると嬉しいが、ほかの多くのアプリ同様、できません。

このバージョンは天文暦が1996年以降のようです。それを境に過去チャートは JST がクリアされます。

とはいえ、チャートはとても美しく大好きなアプリケーションです。

Thank you for liking Kairon. If you have questions, i answer immediately within one business day, but of course not here, this is not the place to ask questions. Yet, it is not true, that you can not set orbs for planets in iKairon: just go to settings:objects and click on each planet and see, what orbs are set and overwrite them to your liking. Sames goes for the aspects. No charts are being deleted and calculations go back to 1200AD and up until 2400AD. Please contact support if you encounter any problems, this is what support is good for. Nobody is left alone with Kairon. And, last, but not leas: Observer your spam folder after you put a request, as unfortunately many of my answers are being filterered out.

Somewhat good

Calculations are very accurate everything is good it would be better if you had the divisional charts available. Other than that good for natal readings.
