Is it dark outside? is a free lifestyle app developed by Dirk Malorny for iPhone. This app uses your current location and time zone to determine whether it is dark outside or not. Additionally, it provides information such as the current position, date, time, and the times of today's sunrise and sunset.

The app is compatible with iPhone, iPod touch, and iPad. For blind users, the app offers accessibility features. If VoiceOver is enabled, simply tap the middle of the screen after launching the app to hear a "YES" or "NO" response.

With its simple and straightforward functionality, Is it dark outside? is a handy tool for those who want to quickly check whether it's dark outside or not, along with related information about their current location and time.
