STO is an app idea that I've been wanting to execute for years, so I thought I'd use it as a platform to gain some experience with Sketch, InVision, Zeplin and Principle. Essentially, the mission of STO is to help you remember where you put things (i.e., where you "STO" them). When you hold the microphone button down, you either tell STO where you're putting an object or ask it where an object is. The app leverages natural language to ascertain the object name and the location name, then it shows you its results, which you can verify or edit before that object's location is (re-)stored.
