Stream Journal is a free iPhone app developed by Karen Grigoryan, falling under the Business & Productivity category. It offers a simple and efficient way to document your life events, thoughts, ideas, goals, and problem-solving strategies. The app focuses on functionality without unnecessary complexities.

The app consists of two main components: the 'Stream' where entries are displayed chronologically, with the latest on top, and 'Sections' where you categorize entries into sections like 'thoughts', 'quotes', or 'my plans'. Users can choose which sections to display in the 'Stream' and customize them as needed. Additional features include a search function to navigate through the journal and the ability to export entries in text format.
