Best activity tracker I've tried
This tracker is very easy to use and the interface with ios7 is crisp and well designed. The only reason I didn't give it 5 stars This tracker is very easy to use and the interface with ios7 is crisp and well designed. The only reason I didn't give it 5 stars is that the bracelet has a very limited life span: it doesn't stand up to even the minimal wear and tear of gently removing the tracking element every few days for recharge, and I can see that I will need to replace my bracelet after only a couple of months. The tracker and charging cable are still fine and this isn't a major drawback as the replacement bracelets aren't that expensive, but they also aren't available everywhere. …

Lots of functionality
I had the Zip, but it just didn't generate enough information. The Flex has a great online app and links to a variety of apps, i.e I had the Zip, but it just didn't generate enough information. The Flex has a great online app and links to a variety of apps, i.e. MapMyRide.
The wrist band takes a bit to get used to and locking the clap can be a challenge until the holes in the band loosen up a bit.
One thing it doesn't do is track cycling. I remove it a put it in one of pockets but it doesn't quite do the job of recording the miles or steps. It also doesn't do steps.
It's worth the money if you are looking to get a handle on your level of activity. …

Inaccurate and flimsy wrist band.
I loved the app design, however the data is inaccurate. On a typical morning (getting out of bed, making breakfast and getting rea I loved the app design, however the data is inaccurate. On a typical morning (getting out of bed, making breakfast and getting ready for work) it would say I had already burnt upwards of 1200 calories. I burn half this amount in an intense workout! Also, after only 4 months of use I woke up to find the wrist strap had snapped in my sleep. The larger strap it came with was far too big for my wrist to use. …

Great product but battery didn't last

Product was easy to set up and use. Tracking sleep patterns was fun but make sure you exit sleep mode in the morning. The pedometer function often tracked steps never taken. For example, getting up right out of bed in the morning, it tracked a few hundred steps while I was sleeping. The biggest disappointment was the battery. It lasted 2 months and I returned it to the Apple store for a full refund. Looking for a a better alternative. Another drawback, it doesn't have a heart rate monitor. …
