I love having a fitness watch on my wrist all day, every day. My tech watch has helped me live a better active and healthy lifestyle. I have owned two Fitbits and now I use an Apple Watch Series 2. If you're looking for a fitness watch, I would highly recommend either of these brands. There is a lot of differences between the two watches, so keep reading to figure out what is best for you.

Overall, based on my experiences with both types of watches, I like Apple Watch better. It offers so much more above and beyond the fitness part of the watch. I like all the extra stuff it comes with. It allows you to basically have your phone on your wrist. I believe that the Apple Watch is built better which is important to me because I went through two Fitbits in two years because they kept breaking. They would scratch easily on the screens. So far, my Apple Watch has no damage and I have definitely accidentally hit it against stuff that would've caused damage to a Fitbit. I like the waterproof feature with the Apple Watch because water was a factor in some of the damage from my old Fitbits. In conclusion, the Apple Watch is more expensive but worth every penny if you look at everything it offers compared to the cheap Fitbit.
