Caffinity helps you understand what your caffeine is doing now - and what may still be active when you go to bed. Log coffee, tea, espresso, latte, matcha, soda or energy drinks in seconds, then follow your estimated active caffeine, half-life curve, daily intake and bedtime level in one place. Enjoy caffeine without guessing when to stop. Real-Time Caffeine Estimate See your estimated active caffeine update as you log drinks and as your body metabolizes caffeine over time. Personalized Half-Life Timeline Follow a live caffeine curve based on your profile and sensitivity settings. Understand how a morning coffee, afternoon cold brew or energy drink may carry into the rest of your day. Bedtime Impact & Coffee Cutoff See an estimate of how much caffeine may still be active around your planned bedtime. Set a personal cutoff reminder so late caffeine does not catch you by surprise. Fast Drink Logging Log coffee, espresso, tea, matcha, lattes, energy drinks and soda with preloaded caffeine values and a quick entry flow. Daily Limits & Smart Alerts Set your own daily caffeine target and cutoff time. Get simple feedback as you approach your limit so you can make the next drink a deliberate choice. Weekly Patterns Review your intake by day, drink and time. Find the routines that work for you and spot late-caffeine habits you may want to change. Streaks & Daily Challenges Build consistency with goals such as staying under your daily limit or finishing caffeine earlier in the day. Water Tracking Keep water logging beside your caffeine routine for a more complete view of your day. Make Caffinity Yours Choose from five themes: Dark Coffee, Cream Latte, Neon Energy, Midnight Blue and AMOLED Black.
