Including heartrate, calories, sleep, and app. What do you think?

I have a Fitbit Charge 2 and it's pretty damn good.

Best value for money you get it from the Xiaomi Mi Band 2. I had the original one and it worked great.
Bought V1.1 for my mother who had sleeping dysfunctions and V2 for my father due to the display.

The heartrate is something that I don't use that much, so for me the best tracker would be the out of market Pebble smartwatch. Love the colour e-ink screen, the sleep recognition is way better than the Mi Band I had, you can see the info easily from the watch, plus you get notifications.

It's a shame Pebble got bought out by Fitbit. They were about to launch new designs with heart sensors.
Maybe have a look at the available smartwatches in the market??

I had the wii fit bit or whatever it was called for a while. I used it mainly for the height indication while cycling, as it was pretty accurate it was fun to see the height map of my trip while cycling. I lost it. Probably for the best as I was trying to set new highscores while jogging all the time, it was exhausting.

This is what I have too.

I have a Samsung Gear S3 and it does all of that and then some. Plus fitness challenges and the chance to compete with other people in "step challenges". Some people are full of shit, though. They get like 100,000 steps in one day.

What? You don't walk 50 miles a day? That's only 8 hours of jogging, you can do it.
