Hey HN! I'm Julio, and I built Superfocus over the past few weeks.

The problem: I noticed college students (including myself) struggle with focus during study sessions. Most Pomodoro timers are either too complex or too boring.

What I built: - Simple Pomodoro timer (25/5/15 cycles) - Custom "vibes" - students can set their own backgrounds + Spotify playlists - Unlimited custom timers (52 min deep work, 90 min sessions, whatever works) - Focus analytics to track productivity patterns - Share achievements on X after completing cycles

It's free with 1 hour/day limit. Premium is $3.99/month with a 7-day trial.

Tech stack: Vanilla JS, Clerk auth, Stripe, Vercel, Resend for emails.

I'd love feedback from the HN community. What features would make you actually use a focus timer?
