Fitbit and what tablet question

[The jiffle king]

The MiL wants a fitbit and we're happy to get her one, but we also know that she needs a tablet/phone to read the displays. She's looking at a Charge or Charge HR and my question is which tablets is it compatible with? (The lists I have found doing a google search are from Jan 2014.

- She really wants the fitbit read out on a tablet
- They have an i-pad2 which is not compatible, so I was hoping to find a cheap tablet solution
- I've toyed with getting her a cheap amazon fire as all she really wants to do is play "words with friends" but it looks like this does not work

Can anyone recommend a cheap tablet which would sync with a fitbit?
Thanks

Many Thanks for the reply, that does help. They do have a PC and are thinking of getting a new laptop, so that might be the best option.

Thanks for all the answers, it's an i-Pad2 they have and it does not work sadly. I'm looking at the simplest to use Android option for them unless they are replacing their PC
