wena 3 is a new smartwatch from Sony Corporation that incorporates smartwatch features into the buckle part while still using traditional analog clock design. This official Android application allows users to configure the wena 3 device and access data obtained from it. Note that this app is exclusively for wena 3 and is not compatible with the previous "wena app".

The app offers different features such as activity logs for steps, calories, and distance, which can be viewed alongside activity history for "Sleep", "Walk", "Run", and more. Additionally, it tracks heart rate and calories, and users can view the intensity of their exercise in three stages based on heart rate data. For sleep, it displays the depth of sleep in four stages: Awake, REM, Light, and Deep. The app also estimates VO2 Max and displays energy levels based on stress levels. Lastly, the app allows users to use various transportation IC/e-money cards such as Suica, Rakuten Edy, iD, and QUICPay on their wena 3 device.
