Depends on what version of Windows it runs. If its RT then the software won't run as those run off of ARM processors rather than the x86 processors that normal PC's run on.
For Apple and/or Android, unfortunately there's no "app for that" that I know of.
Honestly given how cheap Bluetooth receivers/transmitters have become (I bought some for my PC's in the house for less than $2 each) they should be building the Chrono's with those integrated by now, but given how small of a market these products serve they sometimes lag behind in technology.
