Pros
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 Continuously measures your heart rate and intensity level to give you 24 hour stats
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.
Cons
Con My Charge HR, & my newly purchased Fitbit Aspire HR... Aren’t completely compatible w/ my iPhone 11 Pro... Texted messages DONT WORK! Working in a classroom, is the feature I need most!
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 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.
