Synchronise Wallet 3 mac + 1 android and Probably 1 iphone

Hi everibody,
I have 1 imac and 1 Mb Pro + 1 android Phone, my wife have 1 Mb Pro + 1 iphone. Is it possible to reward all the device on the same wallet (Should be interesting to know how much we have together for one month use…)
Any idea ?? cause i don’t find anything to assignate a mail or a user to the app.
Thanks in advance

Anyone have an answer please ??
