Tap/Hold the black circle to see the 2 state animation of the Keezy sound looping app. A circle of circular buttons spins out onto the expanded black circle that becomes the screen background. Once you're on this 2nd state, tap anywhere to return to the initial state. I recorded a webinar showing how to create this interactive animation: http://docs.proto.io/videos/re-creating-bespoke-interactive-animations-with-proto-io-2/ You can also find the assets here used for the prototype. Enjoy!

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.

I used part of the "Laundry App UI Kit Sketch Resource" design that was designed by Satheesh Kumar at: https://www.sketchappsources.com/free-source/3397-laundry-app-ui-kit-sketch-freebie-resource.html to create a quick prototype

Basic To Do prototype based on: https://www.sketchappsources.com/free-source/3625-basic-to-do-app-design-sketch-freebie-resource.html

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.

Here is the first proto upload of Looplist. Looplist is the social marketplace where both businesses and individuals can sell locally. The camera on the top left goes through our identification feature. The whole prototype is still in the works...but something good to look at and is a good reference for our team.
