Disappointing. You cannot use the heartbeat function with other functions. Not even time. Also, the app that uses the watch drains my phone's battery incredibly fast, taking up a lot of space in the process. Not to mention it's not even useful. Eventually the clock will "reset" every now and then (e.g. it says it's 12:00 with no steps or something).
