Garmin’s Vivofit 4 is the perfect easy-to-use, low-cost fitness band for people who aren’t looking for anything too extra or complicated. The Vivofit 4 has a small screen and one button on the actual band, which makes it super easy to use. Coupled with the app, however, users still get in-depth information about their exercises. The best part? This isn’t a fitness band you’ll need to charge every night or even every week as the Vivofit 4 boasts a battery life of up to a year.
