Store description excerpt
HalfCup is a privacy-first caffeine tracking app that helps you understand your caffeine consumption and optimize your sleep schedule. Track every cup of coffee, energy drink, tea, and other caffeine sources with scientific precision. REAL-TIME CAFFEINE MONITORING See exactly how much caffeine is in your system right now. HalfCup uses an exponential decay model based on your personal half-life setting to calculate remaining caffeine levels throughout the day. KNOW WHEN YOU'RE SLEEP-READY Stop guessing. HalfCup tells you the exact time when caffeine levels will drop below your sleep threshold. Plan your last cup wisely and wake up refreshed. PERSONALIZED TO YOUR METABOLISM Not everyone processes caffeine the same way. Adjust your half-life setting based on your sensitivity: - Fast metabolizers (3 hours) - Normal (5 hours) - Slow metabolizers (8 hours) EXTENSIVE DRINK DATABASE Nearly 100 pre-loaded beverages including: - Coffee drinks from popular brands - Espresso-based beverages - Energy drinks (Red Bull, Monster, Celsius, Bang, and more) - Teas (black, green, matcha, chai) - Sodas and soft drinks - Caffeine pills and supplements - Chocolate products - Decaf options Create unlimited custom drinks for beverages not in our database. FLEXIBLE SERVING SIZES Log partial servings with precision. Had half a Red Bull? A double shot? 2.5 ounces of espresso? HalfCup handles decimal quantities accurately. VISUAL DECAY CURVE Watch your caffeine levels decline in real-time with an interactive graph. Scrub through the timeline to see projected levels at any point until bedtime.
