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.

This is an expand/collapse menu example that can be created using container states.

Apply color adjustments and filters to your prototypes to create beautiful interactions and animations. https://proto.io/en/new-features/adjustments-filters/

Re-creation of the onboarding sequence of the app "Service" See how it was done step-by-step in the on-boarding webinar: http://docs.proto.io/videos/creating-great-on-boarding-experiences-with-proto-io/ The app itself: https://itunes.apple.com/us/app/service/id1005945537?mt=8

An on-boarding carousel concept, created using Proto.io. It is implemented using state animations. Feel free to import into your Proto.io account.

This Splash screen prototype shows a vector animation of a headphone made in After Effects. Use the Bodymovin plugin that exports a JSON file and can be dropped right into Proto.io.

The Flipboard animation created using states.

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

First Project, just for fun..
