About the client
IDS Borjomi Russia, the leader of the bottled drinking water market in the Russian Federation, is a part of IDS Borjomi International - the largest producer of natural bottled water in the CIS and the Baltics. 
About the app
Waterbalance app helps people to calculate their daily water intake, control and maintain hydration level in their body. 

The app was launched in 2012 and has become really popular over the years. 

In 2018 the time came to make the app even more functional and user-friendly and IDS Borjomi reached out to Rosberry to accomplish this demanding task. That was a good challenge to face – take the app which is much-loved throughout the world and enhance it to meet the expectations of both new and loyal users. 

To do that we took a fresh look at the UI/UX design and made adding a drink even easier so that a user could do it quicker and on a regular basis during the day. Moreover, we designed the app to be conducive to further updates and enhancements. 
We started working on the project with a thorough research:

1. We studied the stats provided by IDS Borjomi. 
2. We conducted competitive intelligence. 
3. We identified our target audience, profiled it from a social and demographic perspective, found out its movitation as to drinking more water and using the app.
4. We described the personas representing our typical users. 
5. We scripted a user-app interaction. 

The result of this analytical effort was the documentation which became the right framework for starting our development from square one. We’ve maintained and complemented the documentation throughout the whole project. 
Concepting and wireframing
The most important stage is concepting and wireframing. Since the app should be conducive to lots of further updates and enhancements tailored to users’ needs and preferences, we had to lay a good foundation for the app to grow and make progress. 

It was also necessary to come up with a user-friendly process of adding a drink, so that it would take just a couple of seconds and a user could get into the habit of adding each and every drink consumed. 
Adding a drink
Adding a drink in a quick and easy way is ensured in two ways: 

1. One-gesture adding. 
2. Automatic sorting of drinks at the next start of the app. 

In the majority of cases a user will see the drink he needs on the main screen and will be able to just pull it upwards to choose the volume consumed. The users who care much about consumption statistics can specify the details of when and where they drink water just to use this data to understand when and what drinks they drink particularly often. Types of their activities are also sorted based on popularity.
User profile 
A User Profile is the second main screen in the app. It can be opened by simply swiping the main screen down and contains all the user stats known to date.
We have created lots of illustrations to help use the app in an easier way. 

Images of drinks help users to understand how much fluid they have consumed - a cup, a glass or a bottle. 

Achievement icons motivate users to maintain their water balance and get better results.
We have also designed special branded main screen backgrounds for Russia, Georgia and Ukraine which also come and go depending on the season.
Daily water intake calculation formula
The formula was devised by a well-known Russian nutrition expert and a book author. This formula makes allowance for the basic factors influencing the hydration level: physical body parameters, exercising, sleep, meals and weather.
More than 150 app mock-ups
In a simple and effective way the app resolves the main user's task - control over the amount of fluid consumed. At the same time it has a lot of additional functions and internal hidden logic. For example, a user can read hints and tips about drinking water, calculate water intake for a friend or choose the units of measure and the language to be used in the app.
Application for smartwatches based on Apple WatchOS and Google WearOS
It's important that a user could add a drink really quick, so we've developed a smartwatch app companion which allows to add the consumed drinks on the go.
We’ve succeeded at relaunching the much-loved app: long-standing loyal users are happy with the updates and use the app even more often whereas the new ones are sharing great feedback and reviews. For the first two months the DAU number had a 23% increase whereas the all ratings average across App Store and Google Play received the boost of 0,4. That is actually a hefty increase given the app background and the number of active loyal users.   

Waterbalance is going forward to unfold new functionalities, features and enhancements. 
We have been working on the application for over a year. The project has been implemented by: 
Sacha Lopatyuk (Product Owning, Art direction, UX, UI), 
Dima Kashchenko (UX, UI), 
Anastasi Kazakova (UI, illustrations), 
Tatiana Shulgina (UI, illustrations), 
Maxim Pakhandrin (UI, illustrations).
