Sonata Meditations
App Development for Android
About this project
Sonata is an application for meditation and mental health that allows you to learn various techniques of meditation and mindfulness, aimed at bringing a sense of peace, calm, and happiness into your life.
TASK
… Create a mobile application for Android platforms that will allow the user to explore the world of meditation. The user should be able to quickly access meditations, listen to affirmations, or play background music during meditation. View their results in the form of graphs and tables, as well as make notes about their well-being after a meditation session. The Android mobile application should have the ability to authorize/register users, curate meditation selections based on the user's well-being. There should be an option to send PUSH notifications as reminders for training sessions. In-app payment capability through the "Google Play Pay" service.
SOLUTION
To achieve a more reliable application in the end, it was decided to create a native mobile application for Android. For Android, we chose to implement it in Kotlin. The meditation selection automatically sorts lists of meditations from the server based on the user's chosen criteria. The results are displayed in the form of a graph showing the number of sessions listened to and the number of hours listened to. In-app payments were implemented through Google subscriptions, ensuring reliability and security of payments for the user. PUSH notifications were implemented through Firebase Cloud Messaging.
RESULT
In 2 months, our team developed the Android mobile application "Sonata" and published it on Google Play under the client's accounts.

AUDIOGUIDE YARVITTO
App Development for Android
YARVITTO is a true alternative to the usual tour guide. You download the YARVITTO guide, choose a tour, and go for a walk while YARVITTO directs you, tells you all about the places you visit, shows photo materials and a map. And all this WITHOUT INTERNET CONNECTION!
TASK: Create an exact copy of the already completed iOS application "YARVITTO". The main task of such an application is to provide the user with the ability to use audio materials, navigation maps, and photo materials without an internet connection. Also, implement a reminder system for this application on the user's device and a system for evaluating the quality and convenience of using the application.
… SOLUTION: After analyzing the completed application on the iOS platform, we got to work. An OpenStreetMap map was integrated into the application, which allowed us to easily add our own map fragments and use the map without internet access. All materials are loaded once: when the application is launched with the internet turned on, which also ensures the launch of any material without internet access.
RESULT: In 44 working days, our team completed the YARVITTO project and published it on Google Play under the client's account. The application can be viewed at the link https://www.yarvitto.com/ Confirmation of the quality development of the application is evidenced by ratings and reviews on Google Play, as well as the number of downloads of the mobile application. The number of downloads has now reached 10,000 and this figure is constantly increasing.

The Android mobile application must have the ability to authorize/register the user through the "Play Games" service. There should be an option to send PUSH notifications as reminders for training. In-app payment capability through the "Google Play Pay" service.
…
SOLUTION
To achieve a more reliable application in the end, it was decided to create a native mobile application for Android. For Android, it was decided to implement it in Java. Math problems are generated before the start of the game depending on the difficulty level chosen by the user in the settings. The results are displayed in the form of a graph showing the number of correct answers and the date of level completion. Additionally, a table was created showing the number of correct answers for each game. Google Leader Boards were added so that users could see the list of all users in the system and their ranking in that list. In-app payment was implemented through Google subscriptions, ensuring reliability and security of payments for the user. PUSH notifications were implemented using native Android system tools.
RESULT
In 20 working days, our team developed the Android mobile application "MathBrain" and published it on Google Play under the client's accounts.

Apps for iOS (iPhone and iPad)
Wordix – a unique application that will enhance your concentration, reaction, and speed of your brain! You can develop memory, attention, and logical thinking. By performing basic memorization exercises daily, you will also develop visual memory.
TASK

View their results in the form of graphs and tables. The mobile application must have the ability to authorize/register the user via AppleID. There should be an option to send PUSH notifications as reminders for training. In-app payment should be available through the "AppStore" service.
…
SOLUTION
To achieve a more reliable application in the end, it was decided to create a native mobile application for iOS. For iOS, it was decided to implement it in Swift. To reduce the load on the system, data is loaded gradually, and images are cached. This prevents unnecessary user traffic from reloading images. The display of results was presented in the form of a graph showing the number of correct answers and the date of level completion. In-app payment was implemented through AppStore subscriptions, ensuring reliability and security of payments for the user. PUSH notifications were implemented through the Firebase service.
RESULT
In 1.5 months, our team developed the iOS mobile application "Wordix" and published it in the AppStore on the client's accounts.

…
SOLUTION
To achieve a more reliable application in the end, it was decided to create a native mobile application for Android. For Android, we chose to implement it in Java.
User browsing was implemented by displaying cards in a carousel, as is done in most dating apps. Transition to the cards is done by the familiar swipe right or left. For implementing audio/video calls, we used the Tokbox API from Vonage. This allowed us to reduce the timeline and budget for the application implementation. The messaging module was implemented using Firebase PUSH notifications, which also simplified the task, reduced the timeline, and budget.
In-app payments were implemented through Google subscriptions, which guarantees reliability and security of payments for the user.
RESULT
In 3.5 months, our team developed the Android mobile application "TalkLock" and published it on Google Play under the client's accounts.
