On-line Astrology

On-line Astrology computes astrological output directly on your phone. It needs no internet connection and sends nothing to a server — the calculation and its data are part of the installation.

WHAT THE APP DOES

Chart Calculation
Positions of twenty-one bodies including Chiron, both nodes, both Black Moons and the asteroids; houses in six systems (Placidus, Koch, Regiomontanus, Porphyry, whole sign, equal); Part of Fortune and Part of Spirit, Vertex, retrograde motion and a text listing. A graphic chart wheel with the original planetary symbols is included.

Current Horoscope
A horoscope of the sky for a selected moment, independent of birth data. It uses the same chart calculation, text listing and graphic chart wheel as the natal horoscope.

Astrological reports
Long-range listings from the original calculation: Black Moon, lunar nodes, the hypothetical moons Waldemath and Selena, the cycle of Saturn with Uranus, Neptune and Pluto (with and without precession), and Placidus houses. They run in the background and the result stays saved.

Daily Influences
Transits of a chosen day to your natal points with exact times, interpretation texts, Ashtakavarga and Vimshottari dasha.

Alerts
The phone can tell you when the transiting Moon reaches a point of your chart, when two bodies in the sky form an aspect, or when a body enters the next sign. Off until you turn it on.

Chinese Calendar
Heavenly stems and earthly branches for the minute, the watch, the day, the month and the year. Watches are derived from true solar time, not from zone time. The “True MSC” option switches between corrected and uncorrected solar time.

Aku Prediction
A selection of days and two-hour watches by chosen heavenly stems and earthly branches, with the acupuncture points that are open. The result can be saved to a text file.

Planet matches
Your own planetary positions compared against a precomputed index of athletes.

Astrology Learning
A basic course in 58 lessons across seven sections, with review questions. The only part of the app that needs no birth profile — you can open it right after install.

HOW IT COMPUTES

Two theories to choose from: this project's own analytical series from 2000, and series 200 from the Kepler 26 program. You switch them in the settings and the choice applies to the whole app, so two listings from different theories never sit side by side.

The calculation covers 1697 to 2100. A date outside that range is still computed, but the result is marked; the Kepler 26 theory for Pluto is valid from 1885 on.

PRIVACY

The birth profile is stored only in the app's own storage on your device. The app holds no internet permission, so it has no way to send anything anywhere. Uninstalling removes everything.

The app asks for your location only when you press "Use current location" in the profile. The coordinates are written into the place-of-residence fields, where you can see them, and they stay on the phone like the rest of the profile.

HEALTH NOTICE

The app is not a medical device and does not diagnose, treat, cure or prevent any medical condition. The Aku Prediction module provides traditional informational content only. For medical advice, diagnosis or treatment, consult a qualified healthcare professional.

CZECH AND ENGLISH

The language is switched inside the app, independently of the phone's settings.

WHAT IS NOT FINISHED YET

This is an early version. Seven of the twenty-two reports are done and further modules from the web version are on the way. The app only shows modules that can actually be run.
