The recently released Google Inbox app is a re-thinking of the email inbox experience that beautifully demonstrates Google's material design interactive animation language. This prototype focuses on the compose button's animation. Click the + to reveal a new state where a wave of buttons and labels float up, and the + becomes a pencil icon. It uses two states, with staggered animations.

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.

An as close as possible copy of the IFTTT onboarding experience. This prototype is also made in 4 other tools (Pixate, Origami, Framer & Form) to compare the differences between them.

This is just the regular user interface. The introduction and underlying technology are not displayed due to intellectual property. The desired effect here is to show the app's powerful ability to promote local business on any mobile display even one as small as an iPhone 5. New smartphones have much larger screen sizes usually ranging from 4.7" to 5.5". So, showing that the tech works on an iPhone 5 helps us prove this point.
