Add Koku to your Home Screen for quick access - start, pause, and skip sessions right from the widget. Keep the timer visible on your lock screen with Live Activities. Koku also includes an Apple Watch companion app that works with the iPhone app, so you can check your timer and control sessions from your wrist. Designed for iPhone, with an Apple Watch companion. Light and dark mode. Works in any language. Koku (刻) is the Japanese word for a moment of time.
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.

Verdict
The clearest difference is in-app purchases: Koku at none against Noot's 3. Koku also leads on update cadence (every 3 days vs every 9 days). Noot's advantage is iOS requirement (17.0 vs 26.4). On price, ads and device support there is nothing between them.
