How to track water on Apple Watch with Frewli

A water log should not require finding your phone. Frewli on Apple Watch lets you check today's progress and record a drink from your wrist.

The quick version

Install Frewli on the paired Watch, open the iPhone app to sync your goal, and log the amount you drank. Add a complication if you want progress on your watch face.

1. Install Frewli on your paired Apple Watch

Start by installing Frewli on your iPhone. Open it and complete the initial setup so the app has your starting water goal.

To install its Watch app, open the Watch app on your iPhone and go to My Watch. Find Frewli under the available apps and tap Install. Depending on your iOS version, the app list may be under Apps. Apple provides the current steps in Download apps on your Apple Watch.

Open Frewli on both devices with the paired iPhone nearby. Check that the Watch shows your goal and current daily progress. If the Watch asks you to open iPhone to sync your goal, do that before relying on its progress display.

2. Log the water you drank

The first Watch page shows a progress ring, the amount logged today, and your daily goal. It also puts a +250 ml button near the top.

  1. Check how much water you actually finished.
  2. Tap +250 ml for that amount, or open More sizes.
  3. In More sizes, choose 150 ml, 250 ml, or 500 ml.
  4. Look for the log confirmation and updated progress.

The listed amounts are shortcuts for recording, not suggested serving sizes. If none matches your drink, use the iPhone app to record it more accurately. One half of a 500 ml bottle is a 250 ml entry; a full bottle is a 500 ml entry.

Record each drink once. If you logged a bottle on the Watch, do not add the same bottle again on iPhone while waiting for sync. The phone and Watch are views of the same daily record.

Use the wrist to remove a step

Choose one moment, such as a bottle refill, when you normally reach for your phone. Try logging that drink from the Watch instead. This is a small routine change you can evaluate after a few days.

3. Add your water goal to a watch face

Frewli includes Watch complications that display water progress. The information and layout depend on the space provided by your chosen watch face.

  1. Touch and hold your current watch face, then tap Edit.
  2. Swipe to the complication settings and choose an available position.
  3. Use the Digital Crown to find Frewli among the options for that position.
  4. Press the Digital Crown to save, then return to the face.

These are the general steps in Apple's complication guide. Some faces or positions do not support the same complications. If Frewli is missing in one position, try another supported position or face, and check that the Watch app is installed.

Use the face as a quick progress view. Open the Frewli app to log water and confirm a new entry. A complication may take time to refresh, so its display is not a guarantee of an immediate sync.

4. Understand what happens while the phone is away

Frewli keeps new Watch water entries locally while they wait to reach iPhone. They remain in the Watch's progress until iPhone acknowledges them. This lets you record a drink when the paired phone is temporarily unavailable.

When the devices reconnect, open Frewli and allow the record to sync. The Watch's sync status is useful context: a queued entry and an acknowledged entry are different states, even when both are already visible on the wrist.

Avoid repeatedly tapping because the iPhone total has not changed yet. Check the Watch confirmation first. If the totals still differ after reconnecting and reopening both apps, use Frewli support rather than recreating the same drinks on both devices.

The Watch can also show workout recovery context received from iPhone. A water log can contribute to eligible recovery as well as daily progress. The water and sodium logging guide explains how to keep that record consistent.

5. Check where water reminders arrive

Logging from your wrist and receiving an iPhone reminder on the Watch are separate features. Choose Frewli's reminder categories in You > Reminders on iPhone, then enable notifications.

According to Apple's Watch notification guide, alerts normally go to the unlocked iPhone. If the phone is locked or asleep, they can go to an unlocked Watch instead. The Watch app on iPhone lets you manage notification settings; Focus and connection state can also affect delivery.

If the tracking buttons work but an expected alert is missing, check notification permissions and Focus before reinstalling the app. Our water reminder routine guide includes a short troubleshooting sequence.

Common questions

Does Apple Watch measure the water I drink?

Frewli's water record comes from entries you log and any permitted data imports. Tapping a button records an amount; the Watch does not measure your bottle or automatically detect each drink.

Can I log while my iPhone is out of range?

Frewli stores Watch entries locally while they await sync. Open the apps again when the paired devices reconnect and check their sync status.

Do I need to log the same drink on iPhone?

No. Log it once, on the device that is most convenient, and let the entries sync.
