I just spotted a great new messaging app (courtesy of PSFK) called Duet that encourages you to “do things with people you love.”

Heard it all before? Perhaps. But what I like about this new service is that you have the ability to pair yourself with another individual (spouse, colleague, sibling, friend…) and then share activities with them. You get the option to store messages and share photos with your significant other

Duet goes beyond Facebook and Google+ by focusing purely on circles of two which makes sense for people who don’t want to share their thoughts, photos, videos… with their wider social network. Sometimes it’s just nice to share things with someone special.

This intimate one-to-one messaging service is quite sweet and whilst it goes against the current paradigm of the one-to-many broadcast model, I think that it certainly fills a gap that email, MMS and SMS has collectively failed to satiate.

This is how Duet works:

• A duet begins by proposing something you want to do with someone near and dear.
• You can propose duet ideas privately to your favourite people, and create an evolving collaborative life list of all the things you want to do.
• Once each duet is paired, it becomes a private conversation that you can enrich with notes, photos and video messages.
• Your conversations are saved forever and Duet becomes a digital lockbox for the people and memories you cherish most.

As usual, the app is iPhone only (something which is starting to really frustrate me) and can be downloaded directly from the links on Duet’s website: http://duet.me/
