Short answer

Prioritize evidence-based health principles and user safety over solely popular features to create more effective and responsible health applications.

Field: User-Centred Design
Source: Smart Homecare Technology and TeleHealth (2014)
Method: Systematic review of mobile applications.
Sample: 55 applications
Evidence: Moderate effect

Many popular physical activity tracking applications prioritize common features and cost-effectiveness over crucial elements like safety guidelines and tailored workouts for specific populations, potentially hindering their effectiveness in obesity treatment. This user-centred design research insight is drawn from a 2014 study published in Smart Homecare Technology and TeleHealth. Using Systematic review of mobile applications. with 55 applications, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize evidence-based health principles and user safety over solely popular features to create more effective and responsible health applications.

Key Findings

01The most popular features include behavioral strategies, FITT principles, and general physical fitness principles.
02Free apps offer a comparable number of popular features to paid apps.
03Apps with better market ranking often incorporate fitness principles, weight loss goal setting, and training videos.
04Few apps (10 out of 55) met a significant portion (at least 4 out of 8) of ACSM weight loss recommendations.
05Physical activity safety and workouts for special needs populations were among the least popular features.

Application

Design takeaway

Prioritize evidence-based health principles and user safety over solely popular features to create more effective and responsible health applications.

How to apply

When designing a health or fitness application, conduct a thorough review of existing evidence-based guidelines and consider the safety implications for all potential user groups, including those with specific health conditions.

Project actions

01When designing a health app, research established guidelines from reputable health organizations.
02Consider how your design can accommodate users with varying physical abilities or health conditions.

Method & Evidence

AimTo evaluate the features of popular physical activity tracking applications, their impact on market success, and their adherence to evidence-based weight loss recommendations, particularly for obesity treatment.

MethodSystematic review of mobile applications.

ProcedureTwo independent reviewers screened 200 top-grossing iOS health and fitness apps, identifying 55 that focused on physical activity tracking and recording. They then evaluated these apps based on 48 features, assessing popularity, cost drivers, and alignment with American College of Sports Medicine weight loss recommendations.

Sample55 applications

ContextMobile health applications for physical activity tracking and obesity treatment.

Variables

IV["App features (e.g., behavioral strategies, FITT principles, safety guidelines, special needs workouts)","App cost (free vs. paid)"]

DV["App popularity (peak rank, gross sales)","Adherence to ACSM weight loss recommendations"]

CV["Platform (iOS, Android)","App category (health care and fitness)"]

Strengths & Limitations

Strengths

+Systematic review methodology ensures a structured approach to data collection.
+Inclusion of two independent reviewers helps to mitigate bias.

Limitations

The study focused on app features and did not directly measure the actual health outcomes of users.

Reliability & validity

The reliability of the findings is supported by the use of two independent reviewers. The validity is based on the systematic analysis of app features against established criteria, though the direct impact on user health outcomes was not measured.

Think critically

Given that safety and special needs features are less popular, how can designers effectively promote and integrate these essential elements into applications without compromising user engagement or marketability?

Design Principles

"Design for holistic well-being by integrating evidence-based health recommendations, safety considerations, and adaptive features for diverse user needs."

Designers of health and fitness applications must consider a broader spectrum of user needs beyond basic tracking. Incorporating evidence-based recommendations, safety protocols, and adaptive features can lead to more effective and inclusive health interventions.

What This Means for Your Design

Many fitness apps are good at tracking steps and workouts, but they often miss important advice on how to exercise safely or how to help people with specific health problems, which is crucial for losing weight effectively.

Paragraph starter

The review by Wong et al. (2014) indicates that while many physical activity applications offer popular features, there is a notable deficiency in the integration of evidence-based weight loss recommendations and crucial safety considerations. This suggests that designers should move beyond basic tracking functionalities to incorporate scientifically validated strategies and robust safety protocols to ensure the efficacy and responsible application of their products in health-focused contexts.
