Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
iClassics: Beyond Engrossing iClassics unites the old and the new to create immersive experiences that inspire and move everyone. From the producers of the acclaimed iPoe Collection, in this Immersive Entertainment volume, iClassics Productions pulls together a superb collection of tales from horror master H.P. Lovecraft. In this innovative Immersive Entertainment app, a fine selection of horror tales is lovingly and artistically enhanced with interaction, illustration, animation, FX, and OST. This immersive experience includes three masterpieces from the literary legend, including Dagon, The Hound and The Window. By casting a modern glare on these classic H.P. Lovecraft stories, the result is a spectacular and wholly original experience that utilizes every feature of modern mobile devices (gyro-perspective, flash, vibration). TILT to reveal what's in the shadows TOUCH to uncover obscured details TURN to discover what lurks off the screen Dreamy, surreal, dark, and captivating, H.P. Lovecraft transgressed the limits of literary terror in the 20th century. Fittingly, the artistic and technological treatment of his works by iClassics Productions is equally as groundbreaking, hurling his words into the 21st century while keeping the original texts wholly intact. ▶ APP FEATURES: Main features: · An hour of interactive reading · Available in 4 languages: English, Spanish, French and Portuguese · 3 stories, more than 180 illustrations, 50 animations and 60 interactive pages, illustrated and directed by David G.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
