It's no secret that Day One is the best journaling app around. And now you can show your love for the developers yet again by wearing one of their t-shirts, currently available until August 1st, 2014.

They're made from CVC Cotton Poly (60% Cotton / 40% Polyester) and they're "fitted" so sizes run a bit on the smaller side. They're $20 each and you get a choice of charcoal or turquoise. Personally, I hope they add a charcoal shirt with turquoise lettering at some point, but until then, the current options are both quite nice.
