Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Animator Plus is a powerful drawing and frame-by-frame animation studio built natively for iPad and iPhone. Sketch, paint, and bring stories to life on a buttery-smooth Metal-powered canvas — with pro brushes, a full animation timeline, layers, sound sync, and one-tap export to MP4, image sequences, PNG, or JPG. Whether you are a hobbyist doodler, a storyboard artist, a cartoonist, or an animator chasing that classic hand-drawn look, Animator Plus puts everything you need into one focused, beautifully refined workspace. PRO BRUSHES TUNED FOR APPLE PENCIL • Studio Pen — crisp ink lines with subtle pressure response • Pencil — true graphite feel with tilt-based shading • Pressure Pen — thickness scales with how hard you press • Marker — flat, opaque coverage for blocking color • Fountain — calligraphic chisel for elegant strokes • Airbrush — soft sprays that build up gradually • Tapered Line — four variants for classic animation strokes • Eraser, Smart Fill Bucket, Lasso Select Full Apple Pencil pressure, tilt, and azimuth support. Adjust per-brush size, opacity, hardness, flow, and smoothing. • CLASSIC FRAME-BY-FRAME ANIMATION Flip on Animation Mode to unlock a full timeline. Insert, duplicate, copy, paste, and reorder frames in a tap. Set Frame Hold to pause specific frames for any number of ticks. Tune playback from 1 to 60 fps. Onion-skin previous and next frames as ghosts to align inbetweens with confidence. • STROKE-BY-STROKE PLAYBACK Watch your artwork redraw itself, one stroke at a time, at 1x, 2x, or 4x speed. Perfect for time-lapse reels, tutorials, and process videos. Undone strokes are skipped automatically. • POWERFUL LAYERS Stack, rename, hide, lock, blend, and clip layers independently. Every animation frame keeps its own layer stack so foreground action and static backgrounds stay perfectly organized. • SHAPES, TEXT, AND TRANSFORMS Drop perfect lines, rectangles, ellipses, triangles, stars, and hexagons. Add editable text overlays. Use Lasso Select to grab strokes and move, rotate, scale, or recolor entire sections in one gesture. • REFERENCE TOOLS AND ROTOSCOPING Turn on square, dot, or isometric grids for precise layouts. Import a reference image from Photos and dim its opacity to trace or sample. Import a video clip and Animator Plus extracts the frames automatically, letting you rotoscope on top. • SOUND ON THE TIMELINE Import an audio clip, trim the in and out points, and adjust volume. Sound plays back in lockstep with your animation so timing and lip-sync land first try. • EXPORT EVERYWHERE Save your art as transparent PNG, JPG, image sequence, or MP4 video. Push files to the Files app or straight to your camera roll. Projects sync across devices via iCloud Drive. • REFINED FOR EVERY DEVICE Layouts adapt automatically between iPad and iPhone. Customize the accent color, brush smoothing, background color, and grid style from one tidy Settings panel. Whether you are sketching a storyboard, illustrating a children's book, prototyping a cartoon, or producing a finished animated short, Animator Plus gives you the tools to draw, paint, animate, and ship — frame by frame.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
