Show HN: A focus timer that adapts to circadian rhythm (WIP) (flowcycle.vercel.app)

I know, i know — another focus timer... I’m building Flowcycle, an early-stage focus timer experimenting with a simple idea:

Instead of fixed Pomodoro blocks, session length adapts based on time of day, task difficulty, and how focused you felt - called “flow-based Pomodoro” (or Flowmodoro).

It’s very minimal right now: - No signup - One tap to start

This is very much WIP — I’m still validating whether “less choice, more automatic behavior” is actually helpful or just restrictive.
