About

CaffeineX

Features
Read full description

CaffeineX helps you understand how coffee, tea, energy drinks, and espresso may affect the rest of your day. Instead of only counting cups, CaffeineX estimates your current caffeine level, shows a clear 24-hour curve, and gives a simple sleep reference so you can decide whether another drink still makes sense. What you can do with CaffeineX: - Log common caffeinated drinks quickly - Estimate remaining caffeine based on your entries - See when your level may move closer to your sleep reference - Check today's total intake and personal limit - Review recent caffeine patterns over time - Add custom drinks when presets are not enough - Sync caffeine intake with Apple Health if you choose - Use widgets for a quick glance at your status CaffeineX is built for people who like coffee but do not want caffeine to quietly take over their evening. It keeps the interface calm, focused, and easy to read, so the answer is visible fast: how much caffeine is likely still active, whether it may affect sleep, and when it may be better to pause. Caffeine estimates are for everyday wellness reference only and are not medical advice.
