Heart rate monitor step counter calories burnt tracker?

[gooseuk]

So there seems to be tons of step counters calories trackers out there fitbit etc etc. Just wondering what any of you recommend as i could do with one.

Seen quite a few on the cheap via ebay etc but i wonder if there any good.

At the moment i use an app on my phone. But of course thats not accurate all the time.

Thanks to all that can help.
