Animation Desk vs SpineBones

Animation Desk is software for creating animations, cartoons, and animatics on Android, iOS, and Windows. Its tools include paint brushes, layers, onion skinning, sound effects, and frame-rate settings. Work can begin with video clips, photos, or pre-built animation templates, with stock collections, batch frame pasting, and effects for video and images available for editing; some features depend on app version. The product is aimed at beginners, students, learners, and professional animators making rough animation, animatic sketches, or storyboards. Finished work can be exported as video, GIF, PDF, PSD, or image sequences, and editable projects can be exchanged among the Android, iOS, and Windows apps. The iOS listing also describes export to Photoshop for further editing. Animation Desk is free to download, and a free plan is listed. Animation Desk Pro for iOS is $2.49 a month, billed annually at $29.99. Creativity 365 for Individuals is $4.99 a month, billed annually at $59.99. KDAN says the product will remain available under existing paid plans but will not receive proactive new feature development or routine version maintenance updates.

SpineBones is a free 2D skeletal animation editor for creating bone rigs, keying motion, and exporting animations. Rigging includes hierarchies, re-parenting, grouping, and inverse kinematics. Its timeline supports keyframe insertion, movement, selection, copying, looping, per-key easing, and audio tracks. Slots accept PNG, JPG, SVG, and WebP artwork, with multiple attachments and frame-by-frame swaps. Attachment meshes can be deformed with keyed vertices, and onion skin shows neighboring poses. SETUP stores the base pose; ANIMATE keys position, rotation, and scale. Exports include WebM video, transparent PNG sequences, sprite sheets with atlas data, and portable .sbn packages; legacy .json projects open too. An MCP bridge supports Claude and other MCP clients for rig elements, keyframes, frame-rate changes, and exports. It runs on macOS 12+ and Windows 10+, with no account, licence key, or trial timer.
