How to build a water reminder routine on iPhone

1. Start with the bottle you actually use

A tracking routine becomes easier when you know what one entry means. Check the capacity printed on your bottle or measure your usual glass once. Use that amount when logging, rather than choosing a convenient number that does not match what you drank.

For example, if your bottle holds 500 ml and you finish half of it, the entry is 250 ml. If you refill it before it is empty, log the amount you finished first. The goal is a useful record, not a perfectly tidy sequence of full bottles.

Keep water within reach during the parts of the day where you usually forget to log. A bottle on your desk or beside your bag makes the next action visible without another notification.

2. Attach the log to a few existing moments

Pick two or three moments you already notice: sitting down at your desk, taking a lunch break, or unpacking after training. At that moment, check your bottle and log any water you have actually finished. These are recording cues, not instructions to drink a fixed amount.

• Desk routine: put your bottle next to your keyboard and log it before a refill.
• Moving around: log from your wrist if taking out your phone breaks the routine.
• Training day: use the same daily log before and after the workout, then check the recovery card for context.

Do not wait until bedtime to reconstruct every drink if that repeatedly leads to guesses. Move one cue earlier and see whether the record becomes easier to maintain. You can use the Apple Watch logging guide to shorten that step.

3. Set up water reminders in Frewli

1. Open Frewli and go to You > Reminders.
2. Turn on Hydration reminders. Keep the other reminder categories on only if they are useful to you.
3. Tap Enable notifications and allow notifications when iPhone asks.
4. On Today, choose an amount that matches your drink and tap Add water after drinking it.

Frewli separates hydration reminders, workout recovery, weather alerts, and the daily check-in. You can turn those categories on or off individually. The current reminder screen offers these category switches; it does not offer a custom hourly schedule.

Hydration nudges pause after you reach your daily water goal. Future days can still have reminders. That means a quiet afternoon after completing a goal can be expected behavior, rather than a broken notification.

4. If a water reminder does not appear

First, check whether today's goal is already complete and whether the reminder category is enabled inside Frewli. Then open iPhone Settings > Notifications, find Frewli, and check that notifications are allowed.

Focus can delay notifications. If you want a Frewli reminder during a particular Focus, review that Focus's allowed apps. Apple explains both controls in its iPhone notification settings guide.

If you wear an Apple Watch, an alert may arrive there instead of on your iPhone. Apple routes notifications according to whether the phone is unlocked and whether the Watch is locked. See Apple's notification delivery explanation before assuming both devices should alert at the same time.

Open Frewli again after changing permissions so it can refresh its reminder plan. If reminders still do not behave as expected, contact support with your device, iOS version, the reminder category, and when you expected the alert. Avoid including private health details.

5. Review one week, then change one thing

In Frewli, go to You > Your progress to look back at your week. Ask a practical question: was logging easy on workdays, and what interrupted it on training or travel days?

If entries cluster late in the evening, try an earlier recording cue. If you keep forgetting the bottle volume, use the same bottle for a week. If alerts become background noise, reduce the categories you receive instead of adding more.

A streak can make a routine visible, but it is not a reason to chase extra water or invent a missing log. Keep the record honest and start the next day with a routine you can repeat.

Common questions

Can I use Frewli without reminders?

Yes. Water logging and progress work with hydration reminders turned off. Your bottle, meals, or work breaks can be the cue.

Can I choose an exact reminder interval?

The current Frewli reminder screen lets you choose categories. It does not let you set a custom interval or an hourly schedule.

Why did water reminders stop today?

Check whether you reached today's goal. Frewli pauses hydration reminders for a completed day while keeping future reminders ready.
