About Relix Health
Relix is a simple caffeine log. Tell it what you drank and when, and it estimates how much caffeine may still be in your system now and at bedtime. Pick coffee, espresso, tea, an energy drink or whatever you had. Common serving sizes are one tap away. The home screen shows two numbers: an estimate of the caffeine in your system right now, and an estimate of what will be left when you go to bed. Below them, a chart shows your estimated caffeine level rising and falling over the day. If you add your age, weight and sex, the estimate is adjusted for them. Everyone metabolizes caffeine differently, so treat the numbers as a rough guide and not a measurement. Your caffeine log stays on your device, and you can export a backup whenever you like. IMPORTANT Relix is not a medical device and is not medical advice. All caffeine levels in the app are theoretical estimates for informational purposes only. They are not measurements and may not reflect what is actually in your body. Relix does not diagnose, treat, cure or prevent any condition, and it should never be used to decide how much caffeine is safe for you or when to take it. If you are pregnant, have a health condition, take medication, or have questions about caffeine, talk to a healthcare professional. Relix is intended for adults 18 and older.
