I don’t wear one now but I’m thinking after surgery I will start using one. Do you use one and which do you prefer?

My advice is to figure out what you want from it. If having a semi-accurate heart rate monitor with you all the time is important, that'll drive you one way. If having something that doesn't get in your way and maybe isn't even obviously a tracker is important, that'll drive you another way. Do you need it to serve as a watch? How important is sleep tracking? How many other things do you need it to interact with--a scale or your smart lightbulbs or something? (Look, I don't judge.)

The apps vary in quality, but most of the big names integrate with MyFitnessPal, if that's important to you.

I'm pretty into my Misfit Ray which I can wear with a bracelet on the same wrist. It seems accurate enough on the step counts. The app is OK? It's not as fully featured as, say, the Fitbit app, but it works well enough for me. I can't get the swimming functionality to work right, but that might just be that I'm a crappy swimmer, with bad form. ? It talks to MyFitnessPal and Baritastic. It seems to give me a decent read on sleep time and quality.

I've tried out several, so depending what you need I might be able to point you in the right direction, if the Ray isn't the right tracker for you.

I agree with@crankymagpie, you need to decide what features you want. I have a garmin, misfit and 2 samsung gears.

My favorite is the misfit, it syncs and looks like a real watch with the analog face. But when I volunteer I like my samsung because of the other app features.

Research them, compare reviews and find one that works for you.

I’ve never even heard of misfit!! I look into it. I’ve considered getting an Apple Watch too. There are so many!

I have a misfit phase and ray for date nights and swimming. They are all water resistant, but don't want to get my leather strap wet.

The ray I can wear on my wrist, ankle or necklace.

Downside they really only provide progress and reminders not heart rate.

I intend to get a Garmin Vivosmart. Built in GPS, step counters, heart rate....

I have a Fitbit blaze and I love it.
