Caffeine Ceiling tells you how much caffeine is actually in you, reads it against your own daily limit and a sleep-safe line, and gives you a heads-up before you cross either one. It is built for people who have a number they need to respect: a pregnancy limit, a level their heart or anxiety won't tolerate, a cutoff that protects their sleep. Calm and accurate, never a lecture. BE RIGHT ABOUT THE MILLIGRAMS Most caffeine apps guess, and a "cup of coffee" is never just one number. Tea depends on how long you steep it, espresso on the shot count, matcha on the powder, and pods stay deliberately vague. Caffeine Ceiling works from the drink you actually had: size, brew, steep time, shots, powder weight, and how long you sip it. Every drink is editable, and when you correct a number it sticks and stays the same on every screen. SEE WHAT'S IN YOU NOW, AND WHERE YOU'RE HEADED A live curve shows your caffeine rising and falling through the day, projected into the night. You can see how much is in you right now, your daily limit drawn across it, and a sleep-safe line with the time you'll be clear for sleep. The bedtime read is the one most people have never seen before: how much is still in you when you go to bed. A HEADS-UP BEFORE YOU CROSS YOUR LINE Deciding on a second drink? Before you have it, Caffeine Ceiling tells you what it would do, like "this would put you at 215 mg, over your 200 line" or "you'd be wired past 11:40." It is a quiet heads-up, never an alarm, and it never stops you from logging what you actually drank. PLAN AROUND SLEEP You can also work it backwards: the latest you could have a given drink and still be down to your sleep-safe level by bedtime. If a drink can't fit before bed at all, it tells you honestly. THE PATTERN A SINGLE DAY CAN'T SHOW A single night is mostly noise. Over a couple of weeks you can see how often you were over your sleep-safe line at bedtime and whether your intake is drifting up or down. It is a pattern you can act on, stated plainly, with nothing to feel ashamed of. HONEST ABOUT WHAT IT CAN'T KNOW Caffeine metabolism varies from person to person, so your half-life is yours to set, with optional inputs for the things that genuinely change it. The app shows its work: the estimate and the inputs behind it, never a black box. Where the truth is a range, like tea by steep time, it shows you the range. It is an estimate, not medical advice, and it says so. BUILT THE WAY THIS SHOULD WORK - Everything runs on your device. No account, no sign-up, nothing sent to a server. - Log a drink in one tap from your favorites, a widget, or Siri. - Writes to Apple Health so your caffeine stays consistent with your health record. - A one-time unlock for the guardrail features. No subscription. Know your real number, stay under your line, and think about it less.
