Overview
Fitness App is a mobile app that helps users build a sustainable exercise routine through personalized programs, progress tracking, and convenient session planning.
My task was not only to create a modern interface, but also to design a user experience that encourages people to return to the app regularly and achieve their fitness goals.
Challenge
Create an app that will help users:

• get started quickly;
• track your progress;
• stay motivated over the long term;
• choose a program that fits your goals.

Problems
Most fitness apps have the same problem:

1.  users install the app with high motivation;
2.  go through the onboarding process;
3. complete a few workouts;
4. and stop coming back after a few days.

After analyzing the market and user interviews, the following key barriers were identified:

• there's no sense of progress;
• the interface is cluttered with information;
• It's hard to find a program that matches your skill level;
• users get overwhelmed by the large number of workouts.

Research
To understand user needs, an analysis of popular fitness products was conducted:

• Nike Training Club;
• MyFitnessPal;
• Freeletics;
• Fitbod.

Key Insights:

• Personalization boosts engagement;
• It’s hard for beginners to choose a workout;
• Progress is a stronger motivator than content;
• The sheer number of programs creates choice overload;
• Users are more likely to return to the app if they see the results of their efforts.

Hypotheses
01. Create a single space for collaboration

Combine workouts, schedules and communication in a single app
With many fitness services, users are forced to switch between the app, their calendar and messaging apps.
The integration of chat, schedules and the workout process within SweetFit reduces the need to switch between services and makes the user experience more convenient.

impact:

• Improved user retention;
• Increased user engagement;
• Increased number of messages between the client and the coach;

02. Improve the effectiveness of trainers’ work

Centralise client and programme management. Trainers often use several tools at the same time: spreadsheets, messaging apps and separate fitness apps. SweetFit brings together client management, training programmes and communication within a single system.

impact:

• Reducing the time spent on client management;
• An increase in the number of published programmes;
• Increasing the number of active trainers on the platform;

03. Build a scalable fitness ecosystem

Bringing clients, trainers and gyms together on a single platform
Most fitness products cater to just one audience. SweetFit is designed as an ecosystem where each party benefits from the presence of the others.
The more trainers and gyms publish programmes, the greater the value of the platform for clients.

impact:

• an increase in DAU/WAU;
• increased user retention;
• greater engagement with educational scenarios;
