Hydration Tracking

Logging a drink

Open Hydration. There are three quick-add buttons — a glass at 250 ml, a bottle at 500 ml and a large bottle at 750 ml — and a plus and minus pair that adds 250 ml at a time. The minus button removes your most recent entry rather than subtracting a phantom amount.

Before you log, you can choose what you drank: water, coffee, tea, juice, a sports drink, an electrolyte drink, milk, or other. Your log for the day lists each entry with its time, and you can delete any of them.

On the phone, the hydration dashboard works the same way and shows the same day.

Your daily target

ClapDiet does not give everyone the same number. It works out your target on a ladder, and stops at the first rung that applies to you:

If you have a condition managed with a prescribed fluid allowance — chronic kidney disease or heart failure — ClapDiet states no target at all. Your allowance is your clinician's to set, and it is frequently lower than a general figure. The app shows what you have drunk without a goal beside it.

If you are managing kidney stones, your target is at least 3,000 ml. Stone prevention aims at a high urine output, which needs a high intake.

Otherwise it is derived from your profile — from your estimated energy needs at about 1 ml per kcal, or from your body weight at 30 to 35 ml per kg, whichever your profile supports.

If your profile does not yet say enough, the target is 2,500 ml.

The app tells you which of these it used, so a derived number is never presented as a measured one. A derivation that comes out above 5,000 ml is treated as a bad profile entry rather than a very large person, and falls back to the default.

Fill in your weight, height, date of birth, sex and activity level in your profile to move off the flat default.

Which drinks count

Everything you log counts toward the total. ClapDiet records what kind of drink each entry was, so the log is an accurate record of your day rather than a water-only tally.

Reminders

Settings, then Reminders, adds a water reminder at an hour you choose, in your own timezone. On the phone the same thing is a switch in Notification Settings, which sets one up at 10:00 for you.

If you are on Sports Hydration mode

The mode raises your sodium ceiling and potassium floor for training days and adds workout screens on the phone. Those screens read this same hydration log — nothing is logged twice.
