## Description

Clear Outside is a specialized Chrome extension offering reliable weather forecasts tailored for astronomers and sky watchers. It provides seven-day hourly updates emphasizing cloud cover—low, medium, high, and total—to help users find the clearest skies for observation.

Key features include moon rise/set times and phases, sun rise/set and transit information, various darkness phases (civil, nautical, astronomical), and precise International Space Station (ISS) pass-over times calculated for each location. Users can easily search and save favorite locations and access daytime data valuable for solar observers. With frequent hourly updates, Clear Outside ensures users never miss a clear moment for stargazing or astrophotography, making it an indispensable tool for hobbyists and professionals alike.

## Review summary

The app is praised for its feature-rich, astronomy-focused forecasts, moon-phase data, and easy-to-use location management (home + favorites) with an ad-free experience. However, a heavy recurring theme is reduced viability on modern phones: the project appears abandoned and not updated, causing compatibility problems across newer Android versions and devices (S22/S23/S25, Pixel 9). Weather forecasts are seen as less reliable, though moon-phase information remains a strength. Many users keep old devices to maintain access or hope for a revival/open-source continuation.

### Pros

- Location management features (set home and save favorites) with edit/delete options.
- Astronomical forecasts and moon-phase data; highly valued by astrophotographers.
- Easy to use and intuitive interface; works on the current UI.
- Ad-free experience.

### Cons

- Not updated / developer appears to have abandoned the app, leading to lack of support.
- Incompatible with newer Android devices/OS versions; download/install issues on recent phones (S22, S23, S25, Pixel 9, etc.).
- Weather forecast accuracy has declined over time, though moon-phase data remains useful.
- General sense of obsolescence and market withdrawal, causing ongoing accessibility issues on modern devices.
