I don't know for sure since I haven't used that toolkit. If it's anything like other toolkits then you won't have to make large changes. There may be a few elements which don't exist in the other OS or aren't targetable by the same javascript, but not many of them. The toolkit usually has a way to target those with something like if(ios){}, and often have OS or device specific ones like if ios(<8){} or if(device=ipad){}.
