You can add multiple bottles to your account. All linked bottles send the beverage logs to your hydration dashboard, so you have a holistic view of your water intake.

Opening the menu "Device" and tapping “Remove filter” in the Manage Filters bottom sheet opens a confirmation dialog.
The confirmation dialog displays:

• A message informing the user that removing the filter will set the product to “No filter installed” mode.
• A primary action button labeled “Yes, remove filter” to confirm the action.
• A “Cancel” button to dismiss the dialog without making changes.

 
Tapping “Yes, remove filter”:

• Removes the filter from the product settings.
• Updates the product overview to display “No filter installed”.
• Removes any filter tracking data from the Manage Filters section.

Tapping “Cancel” dismisses the dialog without making changes.

The selected day is visually highlighted and drives the rest of the dashboard content.

Users can swipe left or right on the weekly strip to navigate between weeks. Swiping left brings up the previous week, and swiping right shows the next week.
When the user taps on the date in the hydration dashboard header, a full calendar picker appears as an overlay, allowing the user to select any past or current date. The default calendar view shows the current month, and the user can navigate between months and years using arrows or a native picker.  The first day of the calender is 01.01.2025 and the last possible selectable day is dynamically today's date.

The Dashboard data updates automatically based on the newly selected date. If no data for that selected date exists, the empty state is shown.

If the selected day is not today, a “Today” pill appears for easy navigation back.

Go to “Profile” and click on “Hydration target”. Here you can adjust your daily water intake goal.

Users have the ability to request deletion of their MyBRITA account. This functionality is accessible through the Profile section of the app, where selecting the “Delete Account” option allows users to initiate the deletion process themselves. As the deletion is handled externally, the app itself does not process or store any user data related to the deletion request. To complete the account deletion, users are instructed to send an email to appdatapolicy@brita.net with the subject line “BRITA APP request for MyBRITA Account Deletion”.

In the ""My progress"" field, you see a line chart that compares the fluid intake for the selected day with the average intake in the past (last 30 days):

• The dark blue line represents the fluid intake of the current day.
• The lighter blue line, represents the average daily hydration over the previous period of the last 30 days.

The average calculation is carried out as follows: (Sum of hydration values on active days) ÷ (number of active days in the last 30). This average line is displayed from the time the first exposure is registered. At this point, it is not yet visible, as it is behind the current fluid intake. This means that at least one day must pass and the fluid intake of the next day must be different from the exact average in order for the line to be visible.

If there is no beverage protocol for the last 30 days, an average cannot be determined and the display is set to 0 ml by default.

The chart is dynamically updated as the date changes

The central visual section of the hydration dashboard displays two connected components:

• A hydration arc (circular progress ring)
• A bar chart displaying hourly intake volumes

The hydration arc visually represents the user’s current intake as a percentage of their daily hydration goal (e.g., “1236 / 1995 mL = 62%”), filling accordingly.
Beneath it, the bar chart shows a time-of-day breakdown of drinks logged. Each vertical bar represents the volume consumed within a specific hourly window.

Both visuals update dynamically when new drinks are logged or a different day is selected.

"Current Streak" card shows how many consecutive days the user has reached or exceeded his fluid target.
If the user skips a day or logs less than 100%, the series is reset to 0%. This value is recalculated each time hydration data is updated or a new day begins.

If a user changes their drinking destination, this only affects the calculation from the day of the change, while for the past days, the drinking destination set at that time is taken into account.
If no drinking destination has been reached, the map displays "0 days".
If the user deletes his drinking entries on a day in the past and his hydration value fell below the hydration target on that day, we recalculate and update the success series.

“Personal Best” card displays the longest series of consecutive days when the user has reached or exceeded their daily drinking goal. Unlike the current series, which resets when a goal is missed, the personal best performance reflects the user's all-time record - a motivating measure to strive for.
This value is updated only if the current time span exceeds the saved personal best; in this case, the map is updated accordingly. The series is calculated according to the same logic as the current series: Counting per day is only counted if the fluid target is 100% or more. It is only updated when a new record is set and remains unchanged regardless of any subsequent changes or deletions in the drinking history.
If the user has never reached a complete daily goal, the map displays "0 days".

The hydration dashboard includes a Mon–Sun weekly picker at the top, where each day is represented with a hydration arc encircling the date. These arcs visually represent the percentage of the hydration goal reached on that day. Each day’s arc fills proportionally based on the hydration progress, and if the goal is reached or exceeded, a checkmark appears inside the arc.
The hydration arcs update live as hydration data is synced.

In the donut chart I see a breakdown of all the fluids I drank the selected day so that I can better understand what types of beverages I’m consuming. It is shown when there are two or more drink categories logged for the selected day.
The chart visually represents the distribution of intake by main drink categories (e.g., Water, Cold beverages, Hot beverages), with each colored segment proportional to that category’s volume share.
Below the chart, a list displays:

• Category name (e.g., Cold beverages) with a colored dot
• Drink types (e.g., Juice)
• Volume per category and type
• Percentage of total intake per category and type (rounded)
• The center of the chart shows total fluid intake for the selected day.

If only one drink type exists, the donut chart is not shown.
Day can be selected at the top of the screen in the calender.

The following points ensure and show you that hydration tracking is being performed on your BRITA LARQ iQ Bottle:

The LED ring lights up to indicate that a measurement has been taken.
Your bottle must be placed on a flat surface for approx. 2-5 seconds after each measurement, after filling and drinking. The lid must be closed.
Opening and closing the lid triggers a measurement.
If your drink amount is too little, you will need to drink several times. Once a minimum amount has been reached, everything is transferred to your hydration dashboard.

The cap has a built-in sensor for hydration tracking. After filling the bottle and screwing on the cap, place the bottle on a flat table. The cap will glow a white light indicating that a measurement has been taken; this can take up to 5 seconds after placing it on the table.
Hydration tracking works best with cold or room-temperature liquids. Hot liquids will fog up the sensors and tracking will not be accurate.
