Assessing issues and defining objectives

Known issues:

• Many inactive users
  Users become passive in a short period of starting to use the app.
• 30% of users experienced issues with the screening process

Identified current concept issues:

• The outcome parameters are not understandable
  Based on our assumption that the parameters may be unclear for users we've used hallway testing to validate that.
• The main feature (ECG) is hidden
  Hiding the value of ECG, we got into a broad segment of wearable fitness devices, with which we cannot compete in terms of the advancement of the device itself. For example, the Mi band has more features and a very low price due to the lack of developing expensive algorithms and implementing new technologies.

UI/UX improvements that should be done

• New modern UI
• Better UX for the Main flow
• Adding new wellness features

Redesign

#1 Issues with the screening process

There are some issues that prevent getting a good-quality signal:

• Wrong band placement
  Electrodes should be in contact with the skin for the entire screening
• Dry skin
  If the skin is too dry it doesn't conduct electricity.
• Moves
  Moves make noise in the signal.

The 3rd problem has already been solved. The device monitors motion and pauses the ECG screening until the user is motionless. The user interface in the app shows the pause state and displays the information that the user should remain still until finished.

But the first two problems still don't allow users to start screening.
We've started exploring these issues by observing current users' behavior and have highlighted the following points:

As a result, new UI and UX were developed and implemented, which took into account the points found:

#2 Screening Results

Stress has been chosen as the main focus for several reasons:

• We have a metric, HRV, that accurately reflects the level of stress in the body.
• Stress levels are variable and depend on many external and internal factors. We believe this will encourage users to track their stress levels more often and help address the issue of inactive users.
• The problem of chronic stress and burnout is prevalent in our time.

After studying numerous scientific articles about stress, we settled on the concept of "Stress/Recovery."This concept is based on the idea that the key to well-being is finding a balance between the amount of stress we experience and our ability to recover from it.

Exposure to stress over long periods without adequate recovery can lead to physical and mental health problems.

So, based on this conception, a new design of screening results has been presented:

#3 Lifestyle

Before the redesign, the tab was called Activity and only displayed information about steps taken, burnt calories, and distance. However, the redesign has renamed it to Lifestyle and added two new features: Sleep and Breathing sessions, in addition to the existing Activity information.

Activity

The Activity page has been updated with a new UI to ensure consistency with all other screens.

Sleep

The data science team developed a sleep-tracking algorithm that provides the best possible results based on the available data. As similar algorithms were already present in the market, we saw no point in reinventing the wheel. Prior to developing the design, we conducted a competitor analysis, and identified the best implementations.

Based on these findings, we developed a design that meets all required criteria.

Breathing sessions

In the new concept of screening results, we answered the question of users: "What is my stress level now?"
But having received a result in which the user has a high level of stress, a logical question arises, "And what to do next? How to reduce it?"

Understanding this, we decided to add the functionality of breathing techniques. You could see the section with them in the screenshots above. Again, this was not an innovation, it was a period when applications like Calm and Headspace were at their peak, but the main feature that distinguished us from our competitors was the screening.
We combined meditation with ECG screening, thus giving a direct answer: "Did meditation help? How did the performance change?"

So, we had a block of breathing practices within the high-stress results. But this is already a solution to the problem that has occurred. But if we're talking about well-being, it's more about avoiding the occurrence of such results. So we've added a block of breathing practices into the lifestyle so that the user always has access to it.

Outcomes

For the business:

The redesigned app had a significant impact on the company's success.

Firstly, the number of complaints and bug reports to the support team decreased significantly, indicating that users were having a better experience.

Secondly, the retention rate increased from 5% -> 30%. This increase was mainly due to the addition of the breathing sessions functionality, which users found particularly helpful.

Finally, the redesign of the app resulted in a new segment of users, specifically young people, becoming interested in the product.

Results for the customers:

The value increases significantly for users who don't have any heart issues.

The app has become more useful for everyday use since the addition of new wellness features.
