The top 10 apps that help you track your water consumption are Waterllama, Hydro Coach, Plant Nanny, WaterMinder, Water Reminder by VGFIT, Water Drink Reminder, My Water, MyFitnessPal, Google Health (the former Fitbit app) and Apple Health.
Below you will find what each one runs on, how it sets your daily goal, how it reminds you, which health platform it syncs with, and what sits behind the paywall.
Best water tracking app for iPhone and Android
Every app on this list is free to install, and most keep reminders, goals and history behind an optional subscription.
On iPhone and Apple Watch, start with Waterllama; on Android, start with Hydro Coach. If you already log food in MyFitnessPal or wear a Fitbit or Pixel Watch, log water there instead so everything stays in one app. Waterllama calculates a goal from your weight, activity and weather, ships an Apple Watch app and widgets, and syncs water and caffeine to Apple Health. Hydro Coach calculates a goal from age, weight, lifestyle and weather, and syncs your drink log with Fitbit, Samsung Health and Google Fit.
Why use an app to track water consumption?
Most people misjudge how much they drink because nothing records it. A tracker replaces guesswork with a running total and a nudge when you fall behind.
| Problem without an app | What a hydration app does about it |
|---|---|
| You forget to drink during busy hours | Sends reminders between your wake and sleep times, at an interval you choose |
| You do not know your target | Estimates a daily goal from weight, and in some apps activity, age and weather |
| You cannot tell whether today was better than last week | Keeps daily, weekly and monthly charts of your intake |
| Coffee, tea and other drinks go uncounted | Logs separate drink types, often with caffeine or calories |
| Your watch and phone show different totals | Writes each drink to Apple Health, Health Connect, Google Fit or Samsung Health |
The practical benefits of using a hydration app come down to two habits: logging each drink as you finish it, and acting on the reminder instead of dismissing it.

How to log water in the Google Health app
- Open the Google Health app and go to the Health tab.
- Tap Nutrition.
- Tap Add, then Hydration.
- Enter the amount, or pick a preset container such as a glass, bottle or large bottle.
- Set the date and time if you are logging an earlier drink.
- Tap Save.
To change your target, go to Nutrition, open the more options menu and choose Nutrition and hydration settings. Tap any water entry later to edit its amount or delete it.
How to add water intake to Apple Health manually
- Open the Health app on your iPhone.
- Tap Browse to open the Health Categories screen.
- Tap Nutrition, or type Water in the search field.
- Tap Water.
- Tap Add Data at the top right.
- Enter the amount and the time you drank it, then save the entry.
Check that a water app syncs with Apple Health
A water app that syncs correctly makes each logged drink appear in Apple Health within moments of logging it.
- Log one drink in your water app.
- Open the Health app and tap Browse.
- Tap Nutrition, then Water, and confirm the new entry appears with the right amount.
- If it is missing, scroll down to Options and tap Data Sources & Access.
- Make sure your water app is listed and allowed to write data, then log another drink to test.
On Google Health, synced drinks from other apps arrive through Health Connect on Android or Apple Health on iPhone. Manual entries take priority when the same drink arrives from two sources.
Tips for building a consistent hydration habit
- Set a realistic daily target first: start from the app's calculated goal, and change it only on your doctor's advice or once you know your own needs.
- Tune reminders so they help instead of annoy: limit them to your waking hours with the app's start and end times.
- Space reminders at an interval you will actually act on rather than one you will learn to swipe away.
- Log each drink the moment you finish it, using a widget, watch app or preset cup to keep it to one tap.
- Log coffee, tea and other drinks as their own type so the app's history reflects what you really drank.
- Review patterns, not just streaks: open the weekly or monthly chart and look for the time of day or day of the week where you fall short.
- Move a reminder to that weak spot instead of adding more reminders across the day.
Water tracking apps: frequently asked questions
How accurate are water tracking apps?
A water tracking app is only as accurate as what you log. It records the amounts you enter and adds them up; it does not measure what you drink. Preset and custom cup sizes that match your real glass or bottle make the total far more reliable.
Can a hydration app tell me how much water I personally need each day?
No app can tell you exactly. Apps such as Waterllama, Hydro Coach and WaterMinder estimate a goal from weight, activity or weather, and WaterMinder states it is not a medical app. Ask your doctor for a target if you have a medical condition.
Which water tracking apps work best with Apple Watch, Fitbit, or Google Fit?
Waterllama, WaterMinder, Plant Nanny and My Water have Apple Watch apps. Hydro Coach syncs with Fitbit, Samsung Health and Google Fit. Google Health, the former Fitbit app, logs water itself and works with Fitbit devices and Pixel Watch.
Are free water reminder apps good enough, or should I pay for one?
Free versions are good enough for basic logging and reminders in most apps. Pay only for a specific missing feature: VGFIT keeps its Apple Watch app in Premium, and WaterMinder on Android keeps custom reminders and history graphs in Premium.
Do coffee, tea, sparkling water, and sports drinks count toward my daily water intake?
Most of these apps let you log them as separate drink types, and Waterllama lists over 150 beverages. How each app weights non-water drinks against your goal varies, and Google Health tracks caffeine and alcohol separately from hydration.
Does Apple Health track water intake?
Yes. Apple Health stores water in its Nutrition category. You can add entries yourself with Add Data, or let apps like Waterllama and Water Reminder by VGFIT write each drink to it. Apple Health has no water reminders of its own.
Can I log water in the Fitbit app?
Yes. The Fitbit app is now Google Health. Go to the Health tab, tap Nutrition, then Add and Hydration, enter the amount or pick a container, and tap Save. The default goal is about 3.7 L for men and 2.7 L for women.
Is there a water tracker that works on both iPhone and Android?
Yes. WaterMinder, Plant Nanny, MyFitnessPal and Google Health all run on both iPhone and Android. WaterMinder also has watch apps on both sides: a standalone Apple Watch app and a Wear OS app with Tiles and Complications.
Bottom line: which water tracking app should you use?
Install Waterllama on an iPhone, Hydro Coach on Android, or WaterMinder if your household mixes both. If you already track food or wear a Fitbit or Pixel Watch, log water in MyFitnessPal or Google Health instead of adding another app. These apps cover the free basics well, sync with the health platform your phone already uses, and keep your water total in the same place as the rest of your health data.
