GhostTube SLS Camera detects humanoid bodies and homogeneous shapes in your environment similar to the way in which a traditional SLS camera works. On devices equipped with Apple's LiDAR technology, GhostTube SLS Camera uses a projected grid of infrared light to detect depth and for better visibility in the dark. Our complex algorithms use data gathered from the camera and depth sensors to detect people and people shaped objects with accuracy that surpasses that of the Kinect SLS cameras. For devices lacking LiDAR, GhostTube will instead rely on dual lens cameras to measure depth in a similar way to how the human eye detects depth - triangulation of objects based on data from multiple lenses. Some light may be required due to the size or lack of sensors depending on the device you're using. Don't pay hundreds or thousands of dollars for a modified gaming console - GhostTube SLS Camera is available FREE for download and can be used as an SLS Camera in all of your paranormal investigations. For more paranormal investigation and ghost hunting tools, check out our other apps. GhostTube offers auto renewable subscriptions. Refer to our website for a full list of terms and conditions and EULA: GhostTube.com/terms Although GhostTube SLS Camera offers some low light filters, the app is not intended as an aid for seeing in the dark. Always use adequate lighting on your paranormal investigations. Certain shapes and patterns may trigger figures to be mapped by GhostTube SLS Camera.

Draw a frame. Draw the next one. Press play. Simple Motion is a hand-drawn animation studio for iPad and iPhone, built around the way animation is actually taught — a stack of drawings, a timeline, and an onion skin to keep it all moving. Everything a student needs is one tap away, and everything they don't need stays out of the way. **Draw with Apple Pencil, the way it should feel** Ink is pure PencilKit, so it's as fast and as natural as writing on paper, pressure, tilt, double-tap, the lot. Pinch to zoom, twist to rotate the canvas to a comfortable angle, and tap four fingers to hide every tool and see only your drawing. Shape recognition turns a wobbly circle into a clean one when you hold still at the end of a stroke, and the paint fill tool floods an outline in a single tap. **See your animation move while you draw it** Onion skin ghosts the frames either side in red and blue, with independent counts for before and after. Flip and roll through neighbouring frames to check your motion — the fundamental animator's flick, now a button. Playback runs at your project's frame rate with a scrubbable playhead, custom in and out points, and looped ranges. **A timeline that works like a real dope sheet** Pinch the timeline to zoom through five sizes; past the middle rung every cell shows a thumbnail of the drawing on it. Hold a drawing across frames, build cycles and ping-pongs from a range, drag frames to reorder them, copy and paste between layers and projects, and use select mode to act on a batch at once. Named, coloured markers keep track of beats and dialogue. **Layers for every kind of animation** Eight layer types: Drawing, Stop Motion, Image, Video, Audio, Guide, Adjustment and Annotation. Shoot claymation with the built-in stop-motion camera and its ghost alignment overlay. Rotoscope over an imported video, sampled on ones, twos or threes. Add a soundtrack and trim, cut and slide it against the picture. Drop in a Guide layer for motion arcs and timing charts that appear over everything and never export. Reorder, hide, lock, merge, duplicate, and set opacity or blend modes per layer. **Colour, assets and references, always to hand** A floating colour palette you can drop anywhere on screen, with a proper picker, an eyedropper with a magnifier, and your five most recent colours one tap away. Build a library of reusable drawings — mouth shapes for lip-sync, a set of hands, a logo — stored with the project and stamped onto the canvas as real, editable ink. Move a whole library between projects as a single file. Pin a reference photo or video in a floating panel, zoom into a detail, and pick colours straight off it. **Made for a classroom** Organise the gallery into folders by class or assignment, search across all of them at once, and sort by name or by what was opened last. Save any project as a template, hand it out, and every student who taps it starts a fresh copy with the canvas size, frame rate and guide layers already set — the original is never drawn on. Back up a project to a single file to collect, archive or move between iPads. **Share it however you need** Export an animated GIF, an MP4 with its soundtrack, a sprite sheet, a single PNG frame, or a numbered image sequence with your choice of naming convention. Stills and sequences can keep a transparent background for use elsewhere. Every export renders at full resolution, whatever quality you preview at. **Nothing is ever lost** Every action that changes a drawing can be undone, several steps back, from the toolbar or the snackbar that appears the moment something is deleted. Two fingers to undo, three to redo, straight on the canvas. Twelve drawings and an idea is all it takes.
