## What is Deep Focus?

Deep Focus - Deep Work Timer is a focus timer app built for deep work and flow. Use it as a study timer, work timer, or coding timer to quickly record how long you stayed focused. Your sessions are saved by project, so you can track progress over time and review your productivity with clear stats and a heatmap. Start the focus timer once, and your focus time tracking and time management habits begin to build naturally.

The reason to use a focus timer is simple. When you can see how much flow time you achieved today, which projects took most of your time, and whether you are staying consistent (streak), it becomes much easier to plan your next session.
