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.

An idea of a draggable share button. Much easier with one hand drag than two clicks. Just drag the share icon and you'll see.

Sliding navigation of Tab Menu

Concept intro of a mobile app. Loading screen and logo animating to the home screen of the app. Content appears in a subtle animation.

Eventually is a new Social Introduction app that allows you to discover and connect to people before, during or after events. Eventually accesses your Facebook events and displays the other invitees that are going to attend the same event as you. After you have matched with an attendee, you are now able to chat to that person. Maybe, you guys want to meet up at the event...? Later versions of the app will incorporate not only Facebook events but also events from other event-managing sites.

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.
