Apple company is working and developing a smart wedding rings, which connect with the couple's ring and let them know everything about the spouse's trajectory and the places visited by him or her.

Better still, if it's deleted or locked it reports off on the other ring, so the other person will know if it's been turned off!
In addition, it will have the ability to show the rhythm of the heartbeat, blood pressure, the amount of sweat and other extremely interesting data

The smart ring is called iDO

iDO smart ring will be reading the wearer's heart signals and inputting the data into Moral Messenger, which will let the other half know if they are committing immoral, marriage-failing deeds. Taking off the ring to bypass this feature won't work, as the ring will send a warning message to your spouse-to-be if you do.

The ring also features a Temper Teller, which changes colour according to the mood of your partner, and Dream Date which reminds you a week in advance of important dates like anniversaries (and gives electric shocks if you ignore them).

Potential advertising slogan for the iDo include 'one ring to rule them all', 'she has to say 'I Do' to iDo' and 'future technology for your future wife'.

Technology is advancing faster and faster and this wonder will soon be at the service of faithful husbands and loyal wives.
