Throughout the day (and night), the Charge HR fitness tracker continuously measures your heart rate.
On the app, graphs show your heart rate throughout the day, providing stats such as time spent in the different zones (peak, cardio, and fat burn) as well as your average resting heart rate for that day.
Pro Can track your elevation so you know how high you've hiked
When connected to the GPS on your phone, the Charge HR is able to keep track of elevation. This is a great feature for hikers who often like to know how much elevation was gained over the course of the hike.
Pro The app and web platform do an excellent job of keeping you motivated
The Fitbit app lets you set goals and milestones which reward you with badges and trophies when reached.
You can also challenge friends and family, competing against them for top spot on the leader board.
Pro Compatible with nearly every smartphone
In addition to Android and iPhone support, the Charge HR fitness tracker also supports Windows Phone which is fairly rare.
While not an issue most of the time, when upgrading your phone you won't have to worry if your fitness tracker will work with it or not.
Pro Easy to hide under your clothes
The Fitbit Zip fitness tracker is very small, so you can easily wear it somewhere that it will be hidden (belt, pocket, bra strap, etc.). Unlike most trackers which have wrist bands, you don't have to worry about trying to make it blend in with what you're wearing.
Pro Social component to help keep you motivated
The Zip keeps you motivated through friendly competition. Along with giving you a rank among your friends, you can also cheer them on or taunt them.
Pro Fitbit app lets you track a variety of health-related stats
The app doesn't only display the stats from your device, it also lets you track a variety of different health-related stats by entering them manually. You can log your food for the day, how you slept, activity, weight, and more.
Pro Automatic synching that's easy to setup
The Fitbit Zip fitness tracker wirelessly syncs with both PC and smartphones via the Fitbit app. After getting it set up you don't even think about syncing, it's just automatic.
Con Band is poorly made and tends to fall apart
Usually after a few months of wear, people start having issues with the band falling apart. Bubbles will appear under the top layer of the band and then the layers start separating.
The Fitbit Charge HR does not have a replaceable band, so you have to replace the whole device if it is no longer wearable.
Con Notifications are easily missed
While the Charge HR fitness tracker will vibrate to notify you of incoming messages on your phone, the vibration is subtle and short. Sometimes you won't notice the buzz and you'll miss the notification.
Con Stats aren't always accurate
While good enough for most users, the data can be skewed because of physical limits of the fitness tracker. For example, an elevated pulse may just be because you chugged back a coffee, but the Charge HR may interpret this as physical activity. Also, measuring a pulse and steps from the wrist can only be so accurate.
Con Lacking many of the features that fitness trackers often offer
The Fitbit Zip only tracks distance, steps, and calories burned. It's basically a pedometer with a smart tracking platform you can use for manually tracking the rest of your day. It can't tell you stairs climbed or heart rate, and there is no alarm, sleep tracking, or GPS.
Con Issues with the battery not working
The contacts in the device are very sensitive. If you don't place the battery in just right, it will only work for a short period of time before the battery needs to be readjusted or replaced.
Even when following instructions provided by the company, some people report that still can't get it working properly. The battery may end up lasting days instead of the promised 4-6 months.
You can see how to properly change the battery here.
Con Easy to lose
The tiny size of the Fitbit Zip makes it very easy to lose track of.
Rather than a wrist watch like many other trackers, it only has a slide on clip. The clip is fairly secure for normal activity, but you may knock the tracker off without realizing it.
Con Lacks a rechargeable battery
The Fitbit Zip fitness tracker runs on a 3-volt lithium-ion battery that lasts between 4 and 6 months. It requires getting a new battery every time it runs out of charge.
