Flinto

Flinto is a macOS application for building interactive, animated prototypes of mobile, desktop, and web interfaces. It lets designers import screens from Sketch or Figma, then add transitions, micro‑interactions, and gestures such as taps, swipes, scrolls, and 3D touch without writing code. The tool includes a Transition Designer for animated screen changes and a Behavior Designer for button clicks, switches, looping animations, and scroll‑based effects.

The app provides a set of vector drawing utilities, allowing users to create or edit UI elements directly within Flinto, and supports advanced animation controls like cubic‑bezier and spring easing. Additional features include haptic feedback, sound effects, video and GIF layers, 3D rotation, and scrolling areas that can be nested. Prototypes can be previewed in real time on iOS devices via a companion viewer app, and exported as video or GIF recordings.

Flinto targets designers who need a fast, code‑free workflow for prototyping and presenting app concepts. Its integration with popular design tools, extensive gesture library, and export options make it suitable for creating high‑fidelity, interactive mockups that can be shared or posted online.
