Figure 1: アップデート中の様子
個人的に気になる点は次の3点です。
- Initial support for blood oxygen (SpO2) monitoring. Not enabled in Pebble mobile app yet.
- Larger timeline cards. Sports scores and calendar events make better use of the larger displayes.
- Translations are now managed in a community project, making it easier to contribute and keep laguages up to date. Additional languages are delivered as language packs through the mobile app.
