«Meditation is a tool that helped me get up from the bottom. And I want this tool in everyone's pocket!
I want people to know that it's EASY! I want them to turn on a torch instead of feeling their way in the darkness.»

Main idea

Main idea

Meditation is easy! The world is changing rapidly. Every person needs a regular "reboot". Ten minutes to meditate is an easy way to clear the mind, restore energy, and keep perception pure. The application creator wants to make meditation clear and simple. Irena is convinced that meditation helps her to become more sincere with herself, to understand her goals and priorities, to get ready for changes and development. The author’s idea is that the art of meditation should be available to everyone, regardless of their experience, so that even newcomers can gradually get involved and improve their new skills.

How it works

How it works

Just put on your headphones, turn on a lesson, and follow the step-by-step audio instructions.
After downloading the application, you get a 7-day free period.
Over 60 lessons are divided into courses.

  • Basics (work with breathing and body).
  • Sleep (practice simple rituals for a quiet resourceful sleep).
  • Stress (getting rid of tension in the body and consciousness).
  • Work (improve concentration and productivity).
  • Happiness (study the nature of inner happiness).
How it works


There were no difficulties during project development. The real challenges started after the release. Together with technical support, we had to get actively engaged in the process of teaching users: some of them did not know basic things even how to subscribe.

We also dealt with issues with the poor quality of some payment systems. This experience enhanced our expertise in the area.

We also faced message issues in Belarus and Kazakhstan as on the territory of these countries, incoming text messages from outside the country are blocked by cellular service providers. We tried to use various SMS services, but they were still blocked. We found a way to cope with this task as well.

We also found out that the text messages were not received by some users because they were just banned. In this case, the users had to contact technical support to get a temporary code.

Another challenge was related to the player. The player's quality was one of the main requirements. The meditations are played online, and we are to receive and process the audio stream in real time, so that playback goes on without pauses. To do this, we changed the format from MP3 to HLS a couple of times. In this case the audio file is divided into small pieces that are easier to send and receive.

We fell in love with this application and it was very important to make it work right so that the customer and especially the users were satisfied. This is why we have always been in touch with technical support, provided personal consultations, analyzed every request, solved problems, and helped to communicate with users, although this was not a part of the project work.


For several days the application was the first in the toplist of the most downloadable applications in the store. The audience grew enormously, and during the first day 33,000 people became users of the application.


Voice plays an important role in the app. The voice timbre helps users to relax, becomes a beacon and indicates the right direction for meditation. For a long time, Irena has been choosing a voice talent for the app to be in harmony with it. So we had to interrupt the project for the searching period. There was a real casting. And Irena is madly proud of the chosen voice and considers it a small victory. Now the app users meditate together with Sergey Chonishvili, a person with a therapeutic voice penetrating deep into consciousness and helping to calm down and relax.

«Why did we choose Citronium? First of all, you were ready to develop using a modern technology stack - React Native, you had specialists in it. It was of high importance for us that you and your developers were open to be interviewed, and we had the opportunity to choose team members for the project. You provided us with everything so that we were able to make the decision in the shortest possible time.

What do I like about working with you? It is the management openness to communication: we were constantly in touch, we never felt information vacuum, we didn’t feel limitations to working hours. We have a global team, and work from all over the world and at any time we kept in touch and promptly got your feedback.

How did the Citronium team work? We performed a code review, we watched the service at the start, we tested the chosen architecture, and everything went perfectly well. The main KPI for us was a flawless launch. It was important for us that users should not face any technical problems at the start, when due to the visitors inflow the servers might be overloaded or fall off, or services might not work. And everything went perfectly well. During the testing stage, we chose the right architecture, the right partners to place our software with, the right service to be responsible for sending texts, and we also used several services to be on the safe side . All was done quickly and as comfortably as possible.

And now, after the application launch, we enjoy your excellent support, prompt reaction and feel technically safe. We understand that we work with experts.

For us, the most important thing is the technical stability and functioning of the developed solution. From this point of view, you do a great job. And our main victory is that at the start, when we received thousands of registrations during the first few days, and thousands of users began to meditate with us, each of them received excellent service and did not face any problems. This is our greatest victory. I recommend Citronium to everybody.»

«At first, we did not know that this project was for a celebrity. We were only told that we should expect huge workload. The news on developing the application for Irena inspired us. Her team made a very good impression on us: very attentive, always ready to listen, understand, make sense of all the issues.

Before the start of the project , our team was interviewed, and I think that was the key to success. As a result, it became clear that we spoke the same language and could trust each other.

I would like to point out that working on a project for a celebrity, and for a wide audience of users increases the responsibility for the result by several times. Generally speaking, in this case, you have to be ready for a high level of stress. After the release, we experienced mass use. It was difficult to predict what kind of issues 50,000 people might face at a time. And Irena's name also added high expectations, which could not be disappointed in any way. Moreover, everything that makes a person famous is put under a microscope. So we were thoroughly involved in the project. We can't say that in this project we did something unbelieveble that went beyond the limits. For us, almost every project is unique and every customer for us is a selebrity in a way. But sometimes it happens so that the project is treated like something more personal. In this case, I personally wanted to explain, set up and show each user how to deal with a particular issue they faced while using the application. I really want everyone on the phone to have this application, because it can really benefit everyone.»
