Simple, beautiful, perfect cribbage board app.
The UI is sleek and minimalist, the UX is intuitive and perfect. It is a beautiful piece of design, free with small ads, but $2.99USD is worth every penny to remove the ads and properly thank the designer. I have several handmade physical cribbage boards, but this app is always with me and an absolute joy to use. Even if you just want to see a gorgeous case study for a single purpose app design using the best capabilities of the underlying tech, this is worth installing, you might learn something.
