Spoon is a dating app concept aiming to make online dating more efficient, and fair. The concept has the following main characteristics: 1) Gender equality ⁠— the app decides who makes the first move; 2) Time efficiency — no need to put in hours of work to meet somebody; 3) Incremental steps towards a clear goal — no limbo states, no endless/goalless swiping; 4) Fairness, respect, and accountability for its users — choosing someone means you commit resources to that person, no second thoughts allowed; 5) Match exclusivity — chat with only one person at a time; no competing for one’s attention; 6) Fast and fluid interactions — chat while both users are online and active, no offline messages. I hope you like it.

The project contains numerous examples completed using variables and conditional logic.

I've put together a quick demo of a menu idea for a mobile website or app. It only took me 20 minutes to build the entire prototype. Feel free to import and dissect.
