The Walking tab is where you can take Lore with you on a walk. Start a short walk, then talk with LoreBot about whatever's on your mind. You can talk out loud or type, whichever you prefer.
Walking with Lore is also part of how you earn your daily points. The Walking tab shows your walks and conversations for the day and when you can start your next walk. You can learn more by tapping the information button in the top-right corner of the screen on the Walking page.
