Good/Accurate pedometer?

Chloooe22

Hello all

I'm looking for a accurate pedometer and have been looking at getting a fitbit flex? I do accounts for my job so I'm constantly typing and I've read that this effects the results of how many steps you do a day?! Strange I know but as ou wear it on your wrist it's moving with the motion of typing.

Does anybody know of another I could purchase ? Maybe one that goes roud your ankle ? Or just any that is accurate. I would prefer if you could link it up to your iphone and use apps such as myfitnesspal and mapmyrun and such but if not it's not a biggy.

Thanks in advance :-) xxx
