Setup asks what you brew most, which grinder you use and which coffee is in it now. Then Today shows that coffee with a Start button. After the brew, tap where the cup landed on the taste compass and give it a rating.
The coach reads how the cup tasted and how it ran, then names one change, such as a finer grind, a longer shot or more coffee for the same water. With a grinder added in Settings, under Grinders and brewers, it gives the exact setting. Tell it whether finer is a lower or a higher number on your dial. The coach is part of Caffeinated Pro. The free plan shows the general rule for each taste.
Caffeinated estimates caffeine from the dose, the method and whether the beans are arabica, robusta or decaf, rounded to the nearest 5 mg. Café drinks use a typical amount for each drink. The time it shows for dropping below 50 mg assumes a five-hour half-life, which is common for adults and differs from person to person. These are estimates, not medical advice.
Turn on Add caffeine to Apple Health in Settings. Each coffee you log adds one caffeine entry. Editing a brew updates its entry and deleting a brew removes it. Caffeinated only writes to Health and never reads from it.
Caffeinated works with Bookoo Themis Mini and Themis Ultra scales. Close the Bookoo app first, because the scale takes one connection at a time, then tap Connect scale on the timer screen. Scales are part of Caffeinated Pro.
In Beanconqueror, export from its settings. Then in Caffeinated open Settings, tap Import from Beanconqueror and choose the file. Coffees, brews and grinders come across. Importing the same file twice adds nothing new.
Turn on Sync with iCloud in Settings on both devices with the same Apple Account. Sync uses your own private iCloud and is part of Caffeinated Pro. Without it, each device keeps its own journal.
Open Settings on your iPhone or iPad, tap your name, then Subscriptions. Select Caffeinated Pro to manage or cancel it. When Pro ends, every coffee, brew and café visit stays in the app, readable and exportable. If more than three coffees are on your shelf, the three newest stay in use and the others wait until you mark one as finished.
In Caffeinated, open Settings and tap "Delete all data". Read the confirmation before continuing. Deletion cannot be undone.
