Sharpify turns focus into something you can actually train — with your eyes. Using your device's TrueDepth camera, Sharpify tracks your gaze in real time. Keep your eyes on the center and the timer counts up. Look away, and it resets. That gentle challenge — holding your attention on one point — is the entire workout. No streak-baiting, no noise. Just you and your focus. WHY IT WORKS Attention is a skill, and skills grow with reps. Each session asks for a little more presence than the last. Over days, holding your gaze gets easier — and so does staying with a task, a book, or a conversation in real life. HOW IT WORKS • Look at the center circle to begin • Hold your gaze — the timer builds • Glance away and it resets to zero • Complete the session to advance FIVE PROGRESSIVE LEVELS Start at 20 seconds and build toward 180. Each level raises the bar as your focus matures, from "building your foundation" to sustained, effortless concentration. BUILT FOR REAL ATTENTION • Focus Mode — strips away animation and distraction during sessions • Gentle haptics and sound cues (both optional) • Break reminders so you train smart, not hard • Light, Dark, and System themes • A calm, minimal interface designed to lower stimulation TRACK YOUR JOURNEY See total focus time, sessions completed, your best streak, and success rate. Watch your attention span grow session by session. PRIVATE BY DESIGN Your gaze never leaves your device. Sharpify processes face and eye data on-device, in real time. Nothing is recorded, stored, or transmitted — no images, no face data, no gaze data. Ever. MINUTES A DAY No lengthy programs. A single focused session takes seconds to a few minutes. Do one on the train, between meetings, or before deep work. TRY IT FREE Sharpify includes a 7-day free trial with full access. After that, Sharpify Monthly is $4.99/month — cancel anytime in your App Store settings. Sharpify is a wellness and self-improvement tool. It is not a medical device and does not diagnose or treat any condition. Ready to sharpen your mind? Look here. (~2,050 chars — well under 4000, leaves room to expand.)
