Persistent upgrade button animation Designed to demand attention without overpowering the rest of the UI. Small touches are often the biggest differentiator in interaction design. The right animation can guide attention gracefully. Too much and it feels cheap, too little and it goes unnoticed. Timings and subtlety tend to be all you need to nail a delightful moment. In this instance, we aimed to pepper the CTA through the product experience. In features where users could be 'powered up' to complete their tasks. Because of this, keeping the animation subtle reduces the intrusiveness and pressure a user could otherwise feel. No one likes someone standing over their shoulder. Completing tasks within the app with a more pressuring animation would have felt like an unnecessary tension. Keep in simple.
