Flashes is a free social networking app designed for iPhone users, enabling them to capture and share spontaneous moments from their nights out. The app prompts users every hour to take a snapshot of their experiences, ensuring that no memorable moment goes undocumented. This unique feature helps users stay engaged with their surroundings while enjoying their time with friends.

The following morning, users can view and download their captured moments, referred to as "flashes." They can then share these memories with friends, creating a fun way to relive the previous night’s adventures. The app fosters a sense of community by allowing users to browse and engage with their friends' flashes as well.
