Hi there! I would like to share with you the latest version of Spotify prototype. Now you can listen to music while browsing the prototype.

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.

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.

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.

umu assists parents in challenging situations. A crowded day at the beach, a theme park, you name it. A tiny transmitter is carried by the child which's signal is received by the smartphone. When the child is bound to move out of sight or towards a dangerous sight such as water or a busy intersection the parents are alerted. see more at: http://crafting-convenience.com/umu/ Feel free to contact me at: jason@hello-bright.nl

This is a prototype for a café discovery service that I'm developing and it is purely for idea conceptualization purposes only! Please leave comments and let me know what you think!
