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.

Make building your vocabulary fun and simple with WordPal. WordPal is a useful app that can be used to improve your English vocabulary, whether it be to help you sound more intelligent, directly in exams, in word games such as Scrabble or Boggle, with creative writing or anything else. The simple, clean interface allows you to concentrate on learning and progressing swiftly, without any annoying distractions. The app uses a special algorithm centred around the scientifically proven approach of spaced repetition to determine which words you aren’t so confident with, allowing it to prioritise the order in which words are served. This allows you to quickly learn new words and grow your English vocabulary whilst also reinforcing the meaning of words that you already know. The selected words are based on their frequency in the English language in its everyday use, meaning that you are learning words that you don’t know while still being able to use these words every day - there would be no point in learning words you would never use, see or hear! After downloading the app, you will be able to enjoy the many features WordPal has to offer for free: - Pick the synonym of the word given from multiple choice - See the word’s definition(s) to help you better understand the word - See an example for each definition to show the word in context - Access your progress at any time to get a feel for how you are doing; get regular updates of your progress while learning to show how you are improving your vocabulary - 5 progress levels are used: mastered, nearly mastered, getting there, keep trying and work needed — this helps to see how well you know each word - Sleek, clean design - Set a daily goal to help keep you on track and set up notification reminders for specific times of the day, allowing you to improve your vocabulary every day and learn new words rapidly through spaced repetition - Build up a streak (the number of consecutive days you have achieved your daily goal) - Extremely intuitive and simple to use A premium version (WordPal Premium Subscription) is available through subscription which includes more words, games, and the ability to bookmark words. Picking the correct synonym is a very useful method for growing your vocabulary quickly: - Firstly, it makes it easier for you to use more advanced words when you speak or write. If you wanted to find a better word for something, you would look in a thesaurus (a thesaurus shows synonyms for words), but if you know a synonym for each word you learn in the app, you will find it easier to replace that synonym with the more advanced vocabulary word in everyday speech and writing. - Secondly, knowing a synonym serves as a trigger word in your memory to help you remember the general meaning of each word - having this trigger word makes it easier to remember the definitions and examples you have seen in our app when you see or hear a word. Why do our users love our app? - It’s a fun approach that we developed to help users learn English vocabulary - it turns it into a game! - It sparks rapid growth in users’ vocabulary as a result of our special algorithm - It’s so easy to use with the intuitive, simple interface - It’s so easy to understand our definitions and examples - It’s so easy to track your progress The app may be useful in preparation for many exams where a strong vocabulary helps, such as GCSE English, A-level English, SAT, GRE, IELTS, TOEFL, ESL, ACT, GMAT, MAT, CAT, SSC, IBPS PO, Bank Clerk, RRB, SBI, USPC, IAS, NDA, AFCAT and other college admissions tests, placement exams, recruitment tests and aptitude tests.

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.
