Flinto

Mac application for designing animated, interactive prototypes of app and web interfaces

About Flinto

Flinto is a macOS program that interface designers use to show how an app's screens move and respond before development starts. Nathan Manousos and Kazuho Okui started the small, independent California firm behind it in 2012. Prototypes are built visually, without timelines or programming.

What Flinto offers

  • Transition Designer — sets up animated moves between screens by placing elements where they should end up.
  • Behavior Designer — creates micro-interactions inside a screen, such as buttons, switches, loops and scroll-based animation.
  • Gestures and feedback — taps, swipes and scrolls, with haptic feedback and sound effects on iOS devices.
  • Design import and drawing — brings in work from Sketch and Figma, and includes vector drawing tools for mock-ups.
  • Viewer and export — an iOS app for live on-device preview, plus video and GIF recordings of prototypes.

Who it works with

Flinto is made for interface and interaction designers who want to test motion and flow in app designs. The company backs it with documentation, tutorial videos and an active community.
