ZenFocus vs Cairn

Leaving your seat with the timer running? That's not studying. ZenFocus analyzes your AirPods' motion sensor and Apple Watch's heart rate & movement to distinguish genuine focus time from distraction. Not "time spent sitting" — but your actual focused time. [Key Features] ▶ AirPods Focus Detection Your AirPods' motion sensor tracks whether they're worn and how your head moves, so we can tell when you're truly focused. No extra devices needed — just your AirPods. ▶ Apple Watch Integration Check your real-time focus level from your wrist and start or stop sessions right from the Watch app. Heart rate and wrist movement are analyzed together for more accurate tracking. ▶ Detailed Statistics View today's, this week's, and all-time study hours at a glance — and understand your learning patterns. ▶ Nationwide Rankings Compare your study hours with other students through regional and nationwide leaderboards to stay motivated. [Who It's For] • Anyone curious about their actual focus time — not just how long they sat at a desk • Students preparing for exams, college, or certifications who want data-driven study habits • Self-studiers who need motivation to keep going Start tracking your real study time with ZenFocus today.
