The primary project for Apostrophe Apps was our patented storeFront SDK, a plug-in that allowed app developers to sell custom, physical products from within their apps. The logo was used as an app icon for our demo apps, press releases and presentations. It was designed to feature a shop or store front, not to be literal but to make sure that it was clear that this allowed you to set up shop in your app.

The bottom version was the icon I created for the app we used to demonstrate StoreFront SDK live to developers and publishers at GDC '15. (Note that the iOS and Android app stores required square assets - like that one - and trimmed it with rounded corners.) The app worked perfectly, and we gave away a lot of T-shirts that day.
