Ayumi uses the Japanese interval walking method (IWT), which involves alternating between 3 minutes of fast walking and 3 minutes of slow walking, repeated five times. This method is based on research from Shinshu University and is designed to improve aerobic fitness, leg strength, and blood pressure more effectively than steady-pace walking.
No, Ayumi is private by design and does not have any advertisements. The app focuses on providing a clean and uninterrupted user experience without tracking or ads.
Ayumi automatically saves every walk and allows you to browse your full history grouped by day. It provides a 7-day activity chart, a 6-month trend, pace splits, daily streaks, and weekly goals to help you monitor your progress.
Yes, Ayumi is also available on Apple Watch and can run independently. You can leave your phone at home and still access live heart rate, heart-rate zone charts, and post-walk summaries directly from your watch.
Ayumi offers a 7-day free trial for all features. After the trial, you can choose from monthly ($6.99), 6-month ($19.99), or yearly ($29.99) subscription plans. A one-time lifetime purchase option is also available.
Ayumi can read your heart rate when walking with a chest strap or your Apple Watch. It displays the peak of each fast phase, the average of fast and slow phases, and the time spent in each heart rate zone.
Ayumi is available in English, Turkish, French, German, Dutch, Italian, Spanish, Portuguese, Swedish, Danish, Norwegian, and Finnish, making it accessible to a wide range of users globally.
Ayumi has an age rating of 4+, indicating it is suitable for a broad audience. However, as a fitness tool, it's recommended to consult with a doctor before starting any new exercise routine.
