Apple Health provides the starting point
Your weight forms the basis of the calculation. With your permission, DailySip also uses active calories, workouts and steps from Apple Health. Activity outside workouts and training appear as separate contributions. If Health weight is unavailable, your saved weight can be used.
An active day changes your suggestion
New activity data can change your goal during the day. A workout or extra steps can therefore contribute to the calculation. Open “How your goal was calculated” to see the individual contributions instead of just a final number.

Weather you can put in context
DailySip considers your local daily maximum temperature. At 23 °C or above, you can enable weather mode; above 26 °C, the app can suggest it. If you spent most of the day in cool rooms, turn it off again. You decide whether the heat actually affected your day.
Daily factors add what Health cannot know
Account for creatine, a high-protein or salty diet, sauna, alcohol and fever through daily factors. Select the relevant settings and see how they affect the calculated suggestion.
Understand every contribution
The detail view separates the baseline, activity, workouts, steps, temperature, fever and other factors. Limits and rounding of the result are also shown.
A fixed goal takes priority
Set your own daily goal in Settings to replace all automatic adjustments. This also applies when a medical professional has given you a specific drinking target. The automatic calculation offers orientation and does not replace medical advice.
