## Description

PlanetDroid is a universal astronomy ephemeris app designed for amateur astronomers and planetary observers who value precise data over visuals. It calculates high-precision positions and timings for the Sun, Moon, and planets, including rise, culmination, set times, lunar phases, planetary aspects, and seasonal changes.

Featuring an augmented reality (AR) mode, users can view celestial bodies live through their camera and locate planets or comets in real-time. Additional features include GPS localization, offline location saving, and online retrieval of asteroid and comet orbital data. The app supports detailed calculations such as azimuth, elevation, right ascension, declination, and more, beneficial for engaged star gazers seeking factual astronomy information.

## Review summary

PlanetDroid is praised for its accurate, clear, and telescope-friendly astronomical information, making it indispensable for amateurs and professionals. Users appreciate its simplicity and the precise data on celestial coordinates and events. However, recurring issues include freezing of date and time on newer Android versions, UI layout problems on smaller screens, and minor calculation inaccuracies. Some users also desire GPS-enabled time tracking and easier time-setting features to improve usability.

### Pros

- Accurate and useful for astronomers, especially those using telescopes.
- Provides current celestial coordinates and ephemeris data for planets, minor bodies, and celestial events.
- Simple, straightforward, and efficient without unnecessary graphics.
- Supports local time and date calculations important for astronomical observations.
- Highly appreciated by both amateur and professional users for its functionality and clarity.

### Cons

- App freezes the date and time display on Android versions 12, 13, and 14 unless manually removed from memory.
- User interface issues where large portions of the screen are covered or not fitting properly on small screen devices.
- Minor inaccuracies in equinox time calculations and some typos in abbreviations.
- Lack of GPS-enabled time tracking for certain positions, reducing accuracy in time-related data.
- The need to manually set the time to current occasionally.
