Bluetooth Fitness Smart Bracelet In Tech

[Jennykenny]

I bought one of these at a motorway service station the other day as it looked good value, especially as my Fitbit seems to be wearing out.

I can’t for the life of me work out how to use it. Instructions are nil.
It says Bluetooth, but I have no idea what that means. (I have an IPhone 4S, which might have Bluetooth, but I see no way to connect one to the other.
With my Fitbit I somehow got it connected to my iPad but there was a little ‘doofer’ which I plugged into something. (You can tell I am really well up on technology.) So, have I totally wasted my money??
Was only £20.00 but would still like to get some use out of it.
Thanks.

I'm out of my depth here but, in the hope that someone can fill in the gaps, I'll make a few observations to get you started:

1. It looks like you could have paid a lot less on eBay:

2. I assume that, if your device is to connect to your phone by Bluetooth, it will need an app to feed that data into. Have a look on the packaging to see if there's a link to download the iOS one. Otherwise possibly try this one:

3. Connecting by Bluetooth should involve nothing more than 'pairing' the two devices, which this might help to explain:

Thanks Chris, as always you give a comprehensive answer, but it is way beyond me.
Since it is unused, and in original packaging, it’s going to the nearest charity shop.
I couldn’t live long enough to work it out.
