Cheapest I have seen the Jawbone Up3. Cheapest before that was the one time DickSmith did $45 off $200 which mad it $204. Cheapest on StaticIce is $225.
Black is $197.76, Save an extra 50c by opting for Silver which is $197.24. Save an extra $10 by price matching at Officeworks.
Yes it does not do continuous heart monitoring (only resting heart rate when you wake up) but Jawbone is the only tracker I could find that does smart alarm with an iPhone (Sony I think has it for Android). FitBit has an alarm but you can only set it for a specific time not for a window.
I have had the up24 (previous generation) for about a year and have loved the SmartAlarm feature despite the fact that I have gone through 2 of them.
Slept through two alarms or broken two Up24s?
