Using F.A.T allows you to create quick animations on the go with complete freedom. Simply create a new animation, keyframe the character, adjust inertia settings for subtle secondary movement and then export the skeleton to an industry standard BVH format. With the animation created you can import it into any 3D program such as Blender, MotionBuilder or Cinema4D and more. From these programs, it's easy to either characterise the animation to your character or export it to game engines such as Unity, Unreal Engine, CryEngine, Godot and many more. Navigating the 3D Scene is easy, use two fingers to rotate and three to pan around. A single finger or Apple Pencil is used to manipulate the blue nodes into different poses. After you make a pose you want to capture, simply click the Set Key button. We make changing your keyframes simple. Use either the Copy or Cut Key buttons to move the Red keyframes along the timeline and paste the saved keyframe to a new time or overrite a keyframe. With F.A.T you can also use a procedural inertia system to help create subtle secondary motions on your character. Activate the Procedural Inertia Motion button which will turn on the blue bulb and adjust the slider above it to introduce inertia to your keyframes.

Verdict

The call

The clearest difference is update cadence: F.A.T at daily against Animation Sketch's every 2 months. F.A.T also leads on iOS requirement (9.0 vs 11.0). Animation Sketch's advantage is ratings volume (429 vs 52). On price, rating, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Animation Sketch holds the better App Store score, 3.4 against 3.2. That said, the two scores are not equally well evidenced: Animation Sketch has 429 ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 41% of F.A.T's written reviews are positive against 35% of Animation Sketch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

F.A.T ships an update daily, Animation Sketch every 2 months. Both last shipped on October 24, 2026.
