## What is flow?

**"Dive into Deep Focus."**

flow is a focus timer that records and visualizes your deep work sessions. Designed for engineers, researchers, and designers — anyone whose work requires sustained concentration.

---

### Visualize Your Effort
Your daily sessions are displayed as a heatmap, inspired by GitHub contribution graphs. The more you work, the richer the color. Watching your streaks grow is a powerful motivation to keep showing up.

### Immersive Ambient Sound
Toggle the Deep Ocean ambient sound to instantly block out distractions. Combined with a dark-mode UI, flow creates a personal sanctuary for deep, uninterrupted work.

### Start in Seconds
Just open the app and type. Smart suggestions from your history appear automatically, so there's no complex project setup. One tap and you're in the flow.

### Color Labels for Instant Clarity
Assign colors to tasks and see your workload at a glance. The Label Distribution screen shows a breakdown of how your time is actually spent — filterable by day, week, month, or all time.

### Daily Reminder
A gentle nudge at your preferred time each day. Build a consistent focus habit without even thinking about it.
