Reasons To Choose The Fitbit Charge 4

Reasons To Choose Fitbit Charge 4

The Charge 4 Is Considerably Cheaper

Simply put the Fitbit Charge 4 is less than half the prices of the Garmin Vivoactive 4. For people who just want a stylish activity tracker that can also track running and cycling, the Charge 4 represents good value for money. 

It's the Best Value for Money Fitbit You Can Buy

It’s amazing that Fitbit have managed to sell so many products, despite most of their activity trackers lacking built-in GPS capabilities. 

Fortunately, the company are finally starting to rectify things with the Fitbit Charge 4. Now you can leave your phone at home when you go running or cycling outdoors. This will almost certainly become a standard feature in most Fitbit products going forward.

Reasons To Choose Garmin Vivoactive 4S

Built-In Music Storage

The Vivoactive 4 includes 3.5 GB of music storage, which works out to about 500 songs. In contrast, the Charge 4 can only control music that is being played through your phone (the Vivoactive 4 can also do this). The following music apps are also compatible with the Vivoactive 4S:

  • Spotify
  • Deezer
  • Amazon Music
  • iHeart Radio

Guided On-Screen Workouts

The Garmin Vivoactive 4S makes full use of the 218×218 pixel screen when displaying the custom training plans that you can access for free. It’s a bit like having a personal trainer on your wrist, guiding you through each rep and set of the training plan. 

Pulse Oximeter

The Vivoactive 4S has a pulse oximeter which can measure your blood oxygen levels. This is useful when training at altitudes, and it can also be used to help assess your stress levels at sea level. 

Pool Swimming

The Vivoactive 4S includes a swimming mode with all the standard swim metrics (SWOLF). The Fitbit Charge 4 is waterproof, but it can’t actually track swimming. 

Advanced Golf Mode

The Vivoactive 4 gives you access to most of the features that you would expect in a dedicated golf watch. This includes: 

  • Yardage to greens (front/middle/back)
  • Yardage to doglegs and layups
  • Yardage to bunkers and hazards
  • Automatic shot distance tracking
  • Manual pin position placement
  • Digital scorecard

Better Outdoor Sports Modes

The Vivoactive 4S is very well rounded in terms of sports and fitness features. The snowsports are particularly impressive, while the water sports are also pretty solid. More specifically, you can track: 

  • Skiing
  • Snowboarding
  • Cross-country Skiing
  • Outdoor Rowing
  • Stand-up Paddleboarding

Much Better GPS Battery Life

GPS battery life is important, because if you use the GPS regularly, it will chow the overall battery of the watch. In this instance, the Vivoactive 4S GPS battery life (15 hours) is literally 3 times longer than the Charge 4 battery life (5 hours). 

It's The Better Smartwatch Overall

Simply put, the Vivoactive 4S is a better sports watch and fitness tracker than the Fitbit Charge 4. The extra features may come at a cost, but if you take any of your sports seriously, it’s probably worth upgrading to the Garmin unit in this case.
