flow - Deep Focus Timer

A focus timer built for immersion. Heatmaps, ambient sound, and smart suggestions. No ads. No account. Just 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.
