Questions
How accurate is it?
Crema uses a standard model: caffeine peaks about 45 minutes after a drink, then halves every 5 hours by default. Real half-lives range from 1.5 to 9.5 hours, so you can tune it in Settings. It gives estimates, not medical advice.
Is it safe during pregnancy?
Many doctors suggest staying under 200 mg a day during pregnancy and breastfeeding. Choose that in the app and Crema keeps count for you, but always ask your doctor.
Can I use ounces instead of ml?
Yes. Choose ml, fl oz or automatic in Settings. Every drink shows the size and the milligrams.
Does it work with Apple Health?
Yes, and it is free. Crema writes each drink to Health as Dietary Caffeine. It never reads your health data.
How do I cancel the trial?
Crema Pro comes with a 7-day free trial on the yearly plan. Cancel any time in iOS Settings, your name, Subscriptions, at least 24 hours before it ends.
