Here’s another great freebie released by Sergey Bykov for what he calls the Ritter App. This includes a free Sketch file for the vector interface, along with a free PRD file for the Principle animation.
You’ll get a lot of different animations in this freebie, so I think it would be more useful to an intermediate-to-advanced designer. Beginners can learn a lot from it as well, but may have a steep learning curve.
We all know and love the plus icon flyout menu of Google. Well, Jardson Almeida created a Friends Invite menu based on a simple Material Design concept.
Everything was designed in Sketch, and imported to Principle for animation. You get both files as freebies to download and toy around with.
Here’s another general swiping freebie made only for Principle users. This is a card swipe interface created for general purpose slideshows or native app UIs.
I think this is the perfect freebie for a beginner who’s just getting into Principle. It’s not so complicated that you’ll feel lost, yet it’s not so simple that you’ll feel trivialized.
Many designers still use Photoshop for interfaces, and it’s also true of this map chat freebie. You can download a PSD file for the interface, and a PRD file for the Principle animation.
It’s a surprisingly tame animation for the style, but it still looks great and functions exactly as you’d expect in a simple maps/geolocation app.
Mobile apps often use loading screens to tell visitors that something’s happening in the backend. One of my favorite freebies in this collection is this loading animation created by Roman Wagner.
It loads individual elements one after another once the loading screen has finished. This animation is very smooth, and completely credible in the realm of mobile app design.
