One tap. Apps blocked. Focus starts. Tapd uses NFC tags to turn starting a focus session into a physical ritual — not just another setting on your phone. Tap your tag, choose your preset, and distracting apps disappear. TikTok, Instagram, Snapchat, YouTube — gone until you tap out. But Tapd isn't solo. It's built for the people you focus with. Join a group with friends, roommates, or family. Watch the Together Meter show who's currently locked in. Compete on the leaderboard — because knowing your roommate has 40 more minutes than you is better motivation than any timer. After each session, see your analytics, track streaks, and watch your focus hours stack up over time. What makes Tapd different: • NFC tap-in/tap-out — focus starts with a physical commitment • App blocking with custom presets — you choose what gets blocked • Group leaderboards and Together Meter — accountability from people, not apps • Analytics, goals, and lifetime stats — celebrate progress, not just limits Download. Tap in. Get to work.
