Log water, weight and supplements

Each one takes a tap or two. Water counts toward your Fuel ring on the days you log it, and never against you on the days you don't.

Water

Log water

  1. 1

    Tap +, then Log water

    Tap the round + button above your tab bar and choose Log water.

  2. 2

    Tap an amount

    Tap 8, 12, 16 or 24 oz and it's added straight away. For anything else, type it in Custom oz and tap Log.

    Today's glasses are listed underneath. Tap one to change it, or swipe it away to delete it.

Hands full?

Say “Log water in Protocol” to Siri. It asks how much and logs it without opening the app. Log with Siri.

Weight

Log your weight

  1. 1

    Tap +, then Log weight

    Tap the round + button and choose Log weight. You can also tap your Weight card and then Log a weigh-in, where your typed entries are listed to fix or delete.

  2. 2

    Type it and save

    Type your Weight, add Body fat if your scale shows it, and tap Save weigh-in. Change the Date to fill in a day you missed.

    Logging the same day again updates that day's reading instead of adding a second one.

Smart scale?

If it writes to Apple Health, weigh-ins sync on their own. Typing one in here sits alongside them, for a scale that doesn't.

Had a DEXA scan?

Open your Body composition card and tap Log a DEXA scan. Protocol calibrates your body composition trend to it.

Aiming for a number?

Give weight a target and a date, or set a daily water goal. Set your goals.

Supplements

Track your supplements

  1. 1

    Add your stack once

    On Today, tap the Supplements card, then Add your stack. Type what you take, like Vitamin D3, and tap Add. Repeat for each one, then tap Done.

    On iOS 26, Import from Health brings in the medications you track in Apple Health.

  2. 2

    Check them off each day

    Tap Mark all as taken to log the whole stack in one tap, or tap each supplement as you take it. The + button's Log supplements opens the same list from anywhere.
