This is an interactive dial pad, created with proto.io. Development & original idea: https://spaces.proto.io/akisioannou Graphic design: George Prentzas

iPad mobile tablet prototype using hotspots, carousel and tab bar for navigation.

Basic layout for a material design shopping app with easy to access categories, and "shopping cards."

I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

Designers can use their favorite design tools like Photoshop and Sketch to design the finest details of the user interface for their app. Single or multiple touch interactions can be applied on any UI element (layer) on each screen. Sophisticated animations can be created on-screen as well as screen transitions, using the powerful timeline animation features that Proto.io offers.

This is prototype was created for the Net magazine article "Design Prototypes That Reel Real - with Proto.io. It includes a step-by-step written tutorial with screenshots here: http://www.creativebloq.com/web-design/design-prototypes-feel-real-protoio-21619311 It's a product concept for juxtaposing two photos and typing a caption about the connection between them. It should look like this. The tutorial starts with bringing in a range of external assets. Then it'll show how to design assets and customize native components within the tool. Interactions will be triggered by gestures, keyboard input, and automatically as the prototype loads, then choreographed along an animation timeline. Enjoy...

This is an example of a Navigation Bar that disappears on any downward scroll and re-appears on on any upward scroll.

This prototype is basically just a Snapchat login very well designed, with most of the replicable elements of their app.
