Literally the most helpful app

You see, I lovvve to joke about being super clingy with my boyfriend because we're really such the opposite that our friends poke fun over it. So sometimes, I'll throw out that we've been together for x amount of hours just to have some icing on the cake xD this app makes that super easy. (It's also great for being serious and actually liking to know how long we've been together haha) DEFINITELY recommend downloading

Great app

It's a great app that tells you and partner how long you have been together down to the second. I never stop being amazed when I look at the app just to smile. It puts a smile on my face and my wife's face just by looking at the app. Great for when you want a pick me up moment.
