United StatesCouverture is a spring and easing curve editor that enables you to supercharge animations in apps, websites and prototypes. Spring, Easing or Timing Curves are made to specify the rate of change in an animation over time. Couverture lets you manage, edit and preview those curves in realtime. It is a powerful way to create sophisticated animations for your creative projects. Highlights: • Top-notch spring and easing curve editor • Store, manage and export curves • Preview animations in realtime • Ready-to-go: Ships with 24 easing curves and 13 spring curves • Curve Export as: SwiftUI, CoreAnimation, UIKit, CSS, Image (PNG), float literals. Floats are compatible with most design tools that support timing curves (like Figma, After Effects, Motion) • macOS Shortcuts support • Optimized for macOS 12+ • Optimized for Mac with M1 (Apple Silicon) Here’s Why You Need It: Great animations are the couverture in the design of top-notch user interfaces, websites and apps. Couverture ships with a great collection of well-defined spring and easing curves. Store and manage your custom designed curves right within the app. Export them as code snippet for a variety of programming frameworks. Generate curve-based CSS Keyframe Animations or save curves as Image files. Magic begins with the insanely playful animation preview. It pushes you to create never-seen-before, more interesting animation curves. They will set your creative work apart. Privacy: I, the developer, believe in privacy as a human right. Couverture does not collect analytics data. All of your data remains offline, on your device, where it belongs. An app ahead: If you like the app, please take a moment to rate it on the Mac App Store. That’s a great way to support indie developers like me.

Simply Awesome!
I love the UI! Makes it not only easy to create custom curves, but so much fun too. Great tool for the bag! Love it!
United StatesSuper Useful. One feature request.
I've used a bunch of animation curve editors over the years. Especially since adding springs, Couverture is among the best. One common gripe with springs is obviously that you never quite know their duration without a bit of work (depending on which framework you're in). So my feature request / wish would be that I could see the duration of the spring animation in Couverture. As a , this would be broken up into 1) when the final value is initially hit/passed (because the spring is going past it) 2) when the spring visually is close/at rest (this could simply be in terms of values being below a 0.5 away from the final target; or maybe it could allow for a custom threshold) 3) when the actual spring animation is fully done. Depending on the spring, these can be pretty similar values or they can be surprisingly different. Either way, it's often hard to reason about these values without some extra work, and it seems like something up Couverture's alley to help with this. Thanks for this great tool. Looking forward to what's next.

Super cool app! Seriously leveled up my animation skills especially for SwiftUI.

Entire curve collections now can be imported and exported as JSON files• Greatly improved performance I regularly update Couverture to make it even better. If you like the app, please take a moment to rate it on the Mac App Store and leave a review. Have anything else you’d like to suggest? I’d love to hear from you → [email protected]
