Workout and exercise apps were the dominant segment in 2024, with a projected CAGR of 27.1%. For product teams and investors, this suggests that core training functionality remains the anchor of the category, even as adjacent health features develop.

By device, the report covers smartphones, tablets, and wearable devices, and identifies smartphones as the largest device segment in 2024.

Wearables are also a crossover story. The report notes that devices such as smart bands and watches that pair with 5G smartphones increase appeal, and that some bands now offer calling and texting. Wearables may also help reduce healthcare costs by encouraging regular exercise, which the report lists among the opportunities for the market.

Demand Drivers

Several drivers support adoption. High disposable incomes and urban lifestyles encourage spending on consumer technology, and cheaper, more efficient products also support demand. Widespread smartphone penetration, improving network infrastructure, and rising health and nutrition awareness drive adoption as well. Mobile network operators also see fitness apps as an investment opportunity.

AI and Personalization

The report highlights the growing role of AI. AI analyzes health data, workout habits, and goals to create customized plans and improve retention, which supports personalized workout plans tailored to individual users. It also reveals user behavior and preferences, helping developers tailor features, recommendations, and interfaces for Japan. In addition, voice and motion recognition provide real-time workout feedback. Retention is closely related to the engagement challenge the report identifies, which makes personalization a relevant lever for providers.
