Room Of Fitness - Personalized Mobile Fitness

By Yijian Lan & Alexander Kübler — Interaction Design Project. Time Frame: Oct. 16 -Feb. 17.


Health is becoming an increasingly important topic in the world today. According to the current Deloitte study, nearly 10 million people are registered in gyms throughout Germany.

Nevertheless, a large part of these memberships are terminated shortly afterwards and the sporting goals are quickly dropped. And that’s why we asked ourselves, what is it that causes so many people to lose their desire or addiction to fitness?

During our research, it has become apparent that it is often due to the large set goals that are completely unrealistic and can not be achieved in a short time. On the other hand, clients of a fitness studio are often treated identically, meaning they are offered the same advice, exercises and training plans. This, in combination, leads to customer frustration, which is often left alone in the gym after a few weeks, and then many exercises are performed incorrectly.

On the one hand, this can lead to injuries, but also to the result that they will not produce any results. And we want to attack exactly these points with Room of Fitness, because we are convinced that as a fitness beginner you need a competent coach at all times and that the individual and the fulfillment of his needs and desires have the highest priority.


Welcome to Room of Fitness, your own digital personal coach. ROF is an intelligent training platform for your smartphone. The application acts as a personal coach, which responds to the wishes, goals and circumstances of users and supports them optimally and individually on their way to their goals. What makes ROF so special is not just the customizable coach, which makes sense especially for newbies, but the community and Location Based Information function of the app.

Within the community, appmates can chat, help, motivate and share their progress. With the LBS feature of the app, you can meet with sports enthusiasts in your area for training and knows no matter where you are, where to find the best training facilities for your needs and where interesting sports events take place.

  • User Profile – The user profile includes classic user data, as well as user settings and statistics.
  • Notifications – The point Notifications represents the message center of the user.

Our process went through 6 phases until the final presentation with a special focus on the iterative design / prototyping and testing of our ideas.

Our Project Process

1. Research

We dedicated the research especially to the subject of fitness and nutrition. Important to us was a scientifically correct and comprehensive knowledge, which we can include in the development of our app. After all, it is exactly in this knowledge and transmission that good ones differ from bad fitness apps.

In addition, we looked at countless fitness apps and analyzed the best according to various criteria. This allowed us to differentiate and assign relevant information and unnecessary information.

2. Synthesis

Based on the findings of our research and the interviews, we synthesized the most important information and created opportunity areas. Based on the findings of these areas, we have defined four specific questions that our app should fulfill. These questions form the basis for the following ideation phase.

3. Ideation & iterative Design

Through several ideation phases and interviews with test persons, we were able to build up an ever more detailed structure of our app. Important for us was mainly the training function and the customizability of the app.These information structures were built first in the minds, on paper and on post-its, then tested by the user with wireframe click dummies and finally with more detailed prototypes from our test subjects.

4. Design & Prototyping

Here are some excerpts of our finished app design. The entire overview of the converted screens can be guessed from the videos in the solution section. We built the design in Sketch and brought it to life in Origami Studio, which is a powerful ptototyping tool from Facebook.

5. Future Thoughts

We assume that future fitness apps will become more and more intelligent and customizable. ROF represents only one way, which can probably be completely overhauled again in a few years. In our opinion, smartphones basically have some disadvantages when it comes to the proper coaching of individuals.

An example of this is the control for proper execution of exercises. As an outlook of our concept, we have considered a solution that is no longer tied to technical limitations, such as a screen. Using the technology of Augmented Reality, a virtual coach could act as a training partner who could more efficiently support the user in the training sessions.
