What is the focus timer?
The focus timer is a Pomodoro-style productivity tool built into flumen. Start a timer for any task to track focused work sessions. When the timer completes, progress is automatically logged to the task. It helps you stay on track and builds a history of how much time you spend on each task.
How does flumen find free time in my schedule?
flumen analyzes your Google Calendar events and identifies gaps between them. It then matches those free slots with your task list, considering each task's priority score, estimated duration, and your preferences. The AI suggests which tasks fit best into each available window so you can make the most of your day.
