Show HN: Three vibrations mean I-Love-U. Android app to spread the love

My wife and I have a private thing where we squeeze each other’s arm three times to say "I love You"

It's a pretty cheesy little thing but sometimes when out in public you don't want to make a big show of affection so you can just squeeze the other person's arm and they know you're thinking of them.

It's also handy when you're in a group and you can see that your partner is stressed out. Just give them a little squeeze on the arm to help them calm down and nobody else in the group realises.

So last week I decided to turn the idea into an app. Press the icon and your partners phone vibrates 3 times.

No UI, no cheesy message just 3 short vibrations. If it's sitting on your desk at work nobody will realise you're getting lovey dovey messages from your partner.

It's free, no ad's, no in app purchases.

I would be keen for feedback. I've been using it for a few days and gotten lots of brownie points.
