While many microapps are created by design teams, you don't need to be a professional designer to create interfaces like a pro. One of the great thing about microapps is that you can use any tool you're comfortable with to design them, so whether you're using tools like Sketch, Adobe XD/Illustrator/Indesign, or a presentation tool, you can create at any skill level. With some creativity, an experience-oriented mindset, and a hack or two, anyone with a computer can easily design microapps using Powerpoint, Keynote, Google Slides, or whatever other presentation tool you like best.
