Squiddle is a free note taking and sketch app on the App Store. It’s meant to be fun and easy for the user without being ugly or sparse.

Oh, and it’s available for free!

When my project partner Patrick (the iOS developer) and I began talking about Squiddle, we decided that words we’d like to hear the user say about the app are words such as “Easy” and “Fun.” This simple guideline was the primary user experience constraint which informed our decisions. Decisions regarding UI and UX details, and even features in the app, were critiqued along that primary guideline.

The app has simple drawing tools and a simple interface. The user can choose pen sizes, ink colors, note background colors (inspired by sticky notes) and can import a photo as the background. As I designed the user interface I aspired to follow the inspirations I gained by looking to works by many of the Bauhaus legends and even the great Dieter Rams. Look at the initial hand sketches below. Tell me what you think!

Software and Tools

The development code was written with XCode by Patrick Rills, an iOS developer based in Boston. The UI was designed with PaintCode, and the homescreen icon was designed with Affinity Designer.
