About

Noot

Starting is the hardest part. Noot makes it lighter. Noot is a focus companion for ADHD — a meme-speaking, cat-collecting focus timer. When you sit down to start, a companion sits beside you: a meme that gets the exact moment you're in, a calm "breathing" ring that times your session without scary countdown numbers, and lofi to settle into. No streaks. No scores. No guilt. You're not broken — you can do this. HOW IT WORKS - Pick a length: quick 15, a bit 25, or deep 50 minutes. - A no-number ring breathes so you can see it's running — no anxiety countdown. - A meme companion speaks at every moment: starting, a mid-session check-in, the give-up wobble (gently: that counted), the finish (celebration), and coming back after time away (no questions). - Lofi radio plays the whole way through. - As you focus, cats wander over. You build a collection of "cats you've met" — a bond that grows with focus time and never resets. MADE FOR THE WHOLE DAY - Home Screen widget + Live Activity on the Lock Screen and Dynamic Island. - Apple Watch app. - iCloud sync — your cats and your bond follow you to a new phone. - No account, no sign-up. Local-first. - Start hands-free with Siri & Shortcuts. NOOT+ (optional) Noot is free forever — focus, memes, lofi, and meeting cats. Noot+ simply brings more friends home: every premium cat, for $2.99/month, $19.99/year (with a free trial), or $29.99 once for lifetime. Family Sharing on. Noot noot. You've got this.
