Not sure how much battery it takes, but it would be awesome if you all expanded the use cases for the haptic alerts. Some ideas: 1) sleep— in addition to wake up alarm add a “go to bed” alert to signal ideal bed time. 2) stress alerts. Haptic alerts if you hit a certain stress threshold (2.7 or above?) for a prolonged period of time (5 min?)— could be used to remind users to practice breathing etc.
