"I laid down for one hour to check out the inactivity feature. And sure enough it vibrated!" - says a happy LEAF owner named Lisa :) The LEAF's inactivity alert has five different levels of desired activity you can set and if you've been inactive for too long, it will vibrate and warn you to move around for a bit. There's a "do not disturb" mode as well - that way, if you're in a meeting and can't really get up and move around, the LEAF won't remind you to.
