About Caffeinly: Sleep & Energy
Caffeine is a tool. Most apps just log it — or just help you quit. Caffeinly times it to your goal. Better sleep, fewer crashes, calmer focus, or cutting back — Caffeinly learns how caffeine moves through your body and coaches you to the smartest time for every cup, and the last safe one before it steals your sleep. Not a diary. Not a quit-app. A coach. WHAT MAKES IT DIFFERENT • A live, personalized caffeine curve tuned to your half-life and sensitivity — watch your levels rise and fall in real time • A smart cut-off time so caffeine clears before bed • Crash, jitter, and sleep forecasts based on your real intake • Learns from your Apple Health sleep to get sharper over time BUILT AROUND WHAT YOU'RE FIXING • Sleep better — see tonight's sleep impact before you sip • Beat the afternoon crash — forecast the dip and time caffeine around it • Calm the jitters & anxiety — stay under your personal overdrive line • Cut back or quit — a gentle, week-by-week taper plan • Sharpen focus — line caffeine up with when you need to perform HOW IT WORKS 1. Answer a few quick questions about your body and habits 2. Discover your caffeine type — Fast Burner, Steady Processor, Slow Clearer, or Marathon Metabolizer 3. Log drinks in one tap (or build your own) 4. Follow your curve and your daily cut-off — and watch your sleep and energy improve Caffeinly is for anyone who loves caffeine but hates the crash, the jitters, or the 2 a.m. ceiling stare.
