The Garmin Vivofit 4 is a budget fitness tracker perfect for those who want to live a healthier lifestyle but don't want to be driven by data; it's also perfect for those looking for a fitness tracker under $100.

For a limited time, Dell is offering the Garmin Vivofit 4 for $49.99. That's $30 off and the lowest price ever for this fitness tracker. This will likely be the cheapest sale on a fitness tracker until Amazon Prime Day later this summer.

There are a few things that aren't worth it: the Garmin Vivofit 4 lacks a heart rate sensor, touchscreen, and built-in GPS. However, it makes up for it with a one-year coin battery and a waterproof design.

In our review of the Garmin Vivofit 4, we used the device to track steps, distance, calories burned, and active/workout minutes. In our tests, it did an excellent job of tracking workouts. To our surprise, it was also good at recording non-cardio workouts. It works with Garmin's Move IQ technology, which automatically detects what type of activity you are doing based on your wrist movements. Workouts can also be recorded manually or entered retroactively through the Garmin Connect app for iOS or Android.

The $50 Garmin Vivofit 4 is ideal for casual users who don't want to be swayed by confusing metrics.
