Callipeg

Callipeg is a high-performance 2D hand-drawn animation software engineered specifically for the iPad and Apple Pencil ecosystem. Utilizing Apple's Metal API, the application provides a fluid, low-latency drawing experience that mimics the precision of desktop-class software like TVPaint or Toon Boom Harmony. By 2026, Callipeg has solidified its market position as the leading 'mobile-first' professional animation suite, catering to independent creators and boutique studios who require portability without sacrificing technical depth. The software architecture focuses on a non-destructive timeline, allowing for complex layering, advanced onion skinning, and transform keyframing. Its technical advantage lies in its memory management, enabling high-resolution projects with hundreds of layers on modern M-series iPad chips. Callipeg supports a full production pipeline, from initial storyboarding and rough animation to final cleanup, coloring, and multi-format export. As the industry moves toward decentralized, mobile-ready production workflows, Callipeg serves as a critical node for animators seeking professional brush engines and robust timeline management on the go.
