Nagi

Read full description

Most focus timers try really hard to keep you engaged. Streaks, badges, leaderboards, trees you have to keep alive. At some point the app itself becomes the distraction. Nagi is different. It's just a timer. Instead of numbers ticking down, you see time as a 30x30 dot-matrix pattern that fills in gradually — abstract, calm, and completely free from the anxiety of watching seconds disappear. When your session ends, you get a gentle notification. That's it. No guilt if you skip a day. No rewards for showing up. Just honest, quiet focus. WHAT YOU GET - A unique dot-matrix time display that shows progress without pressure - Pomodoro sessions with three built-in presets (25/50/90 min focus) - Automatic work-to-break transitions so you don't have to think about it - Tag your sessions (Work, Study, Creative, Exercise, Personal) to see where your time goes - Today's session timeline at a glance - Home Screen and Lock Screen widgets for your daily and weekly focus - Live Activities and Dynamic Island show your session without opening the app - Light and dark themes using Catppuccin palettes — warm colors that are easy on the eyes - Notification sounds you can customize or turn off entirely - Works offline. Always. WHAT YOU WON'T FIND - No streaks or daily goals - No points, badges, or achievements - No leaderboards or social features - No account sign-up - No cloud tracking - No ads, ever NAGI PRO Nagi is free to use. An optional Nagi Pro subscription unlocks: - Custom focus and break durations (any length you want) - Custom tags for your sessions - Full session history and weekly insights Available as a monthly or annual subscription, or a one-time lifetime purchase. Subscriptions renew automatically until cancelled in your App Store account settings. YOUR DATA STAYS YOURS Everything is stored locally on your device. No accounts, no analytics, no servers collecting your focus habits. Your sessions are nobody's business but your own. WHY "NAGI"? 凪 (nagi) is Japanese for a calm, windless sea. That's the feeling we're going for — focus that feels like stillness, not a race. Built by one person who got tired of focus apps that felt like productivity homework. If you just want a timer that works and stays out of your way, this is it. --- Pomodoro Technique® is a registered trademark of Francesco Cirillo.
