autoTween Animate for Android

11 things about autoTween Animate

1. After drawing a pencil stroke or shape on the canvas, a numeric label appears which defines the "mapping" for in-betweening strokes between adjacent keyframes.

2. autoTween Animate is an animation app that makes the process of in-betweening key frames easier by automatically interpolating pencil strokes between keyframes.

3. The app supports up to 12 layers and 2000 frames, variable-length onion skins, modifiable playback speed/range, layer visibility toggling, and copy/remove/clear/paste frames.

4. One recommended workflow is to first sketch key frames in one layer, then draw over those sketches in a methodical way on other layers.

5. The order in which pencil strokes are drawn determines the default mapping used for interpolating the strokes of keyframes.

6. These numeric labels can be dragged to other strokes on the canvas so that the mapping is flexible.

7. One presses the 'autoTween' button to then automatically generate the sequence of frames in the active layer between the two adjacent key frames.

8. This includes and is not limited to email addresses, other installed apps, user names, browsing history, photo albums, and device identifiers.

9. There are no subscriptions, ads, tracking, nor in-app purchases.

10. The app is supported by its one-time purchase price.

11. Export is easy to mp4, jpg, and png.
