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
Science-based Big Five analysis Not a fortune-telling app. This app is a science-based personality test built on the Big Five (BIG5) personality model, one of the most widely used frameworks in psychological research. Instead of labeling you as “good” or “bad,” this app helps you understand your personality tendencies objectively through five core traits. 【What is the Big Five (BIG5)?】 The Big Five model describes personality using the following five traits: ・Openness ・Conscientiousness ・Extraversion ・Agreeableness ・Neuroticism These traits are not judgments or diagnoses. They simply represent different tendencies in how people think, feel, and behave. This app visualizes your results using clear charts and explanations, making it easy to understand your personal profile. 【Key Features】 ■ Science-based personality assessment This app is grounded in established psychological research. There are no spiritual, fortune-telling, or entertainment-based elements. It is designed as a calm self-reflection tool for understanding yourself more clearly. ■ Choose your test depth Select the level that fits your time and interest: ・20 questions: Quick overview ・35 questions: Standard assessment ・50 questions: More detailed analysis All modes provide results in the same clear format. ■ Simple and intuitive design Answer each question using a 5-point scale. No complicated settings or controls — just focus on your responses. ■ Save and review your results Your test results are saved in the app so you can: ・View past results anytime ・Review them in a calendar-style history ・Compare scores across traits This allows you to use the app not just once, but over time. ■ Track changes over time Personality tendencies are not always fixed. They can shift depending on environment, context, or life stage. This app lets you track each trait over time using charts, helping you observe changes objectively. ※ Changes are not evaluated as good or bad. ■ Cloud backup for peace of mind You can save your results to the cloud and restore them when switching devices. ・Safe when changing phones ・Restore after reinstalling the app Sign-in is optional. ■ One-time purchase, no ads ・No advertisements ・No subscriptions ・No additional purchases Buy once and access all features in a distraction-free environment. 【Who is this app for?】 ・Those who want a science-based personality test ・People interested in psychology and self-understanding ・Users familiar with MBTI who want a more research-based approach ・Anyone looking for a calm, trustworthy self-reflection tool 【Important Notes】 ・This app is not a medical or mental health diagnostic tool. ・Results indicate tendencies only and do not define your value or abilities. ・The app does not provide treatment or professional advice. BIG5 Personality Test: Science is designed to give you quiet, objective insight into your personality. Take your time, reflect calmly, and get to know yourself better.

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.
