Flowcus

Flowcus (formerly Flowbound) is a focus coach built by Su for people who procrastinate: short in-the-moment prompts to move through anxiety, confusion, or boredom; a small companion timer; and a place to park the thoughts that pull you away. Instead of willpower theatrics, it runs quick focus experiments and remembers what actually lifts your energy — a "personal playbook" approach to getting unstuck.

The build story is documented in Lenny's Newsletter's "What people are vibe coding (and actually using)": listed as "Find out what's blocking your flow, by Su using Bolt," with Su's own words: "Flowbound is an app that gives me games/exercises to do when I find myself procrastinating on something (which is often)." The site itself says "Built by Su — a coach helping overwhelmed professionals get unstuck," with account data in Supabase and companion responses generated by Anthropic and OpenAI models.

It kept evolving after the newsletter feature: the product rebranded from Flowbound to Flowcus and now runs a limited beta with simple transparent pricing and a waitlist. A vibe-coded productivity tool with real users, real iteration, and a refreshingly humane design thesis.
