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.

Birthdays are easily forgotten. Wouldn't it be great to be reminded of the most important day of your family members and friends. BIRTHDAYS Keep an eye on all birthdays – Birdees shows a list of all upcoming birthdays. Customize the list according to your needs - do you want to see past birthdays or want to peek into the future? And for a quick overview, you can use the Today widget that shows the next four upcoming birthdays. With Birdees, you can import the birthdays right from your contacts, but also create new birthdays without the need to create a contact first. This keeps your contact list clean, but still reminds you of upcoming birthdays. You can use iCloud synchronization to share your birthday list between multiple iOS devices. REMINDER Let Birdees remind you of upcoming birthdays - how often and whenever you like. Birdees is the only birthday app where you can set an unlimited amount of notifications. This means that no birthday will be forgotten anymore. GROUPS Use different groups for your family members, your friends and colleagues. Set your reminders on a per group basis and determine the right time to be notified for each birthday. UPDATES A long list with further improvements to make birthday management even easier is already next to me on the table. I'm constantly working on keeping Birdees up-to-date and enhancing the app. If you notice something that is not working yet or something that would make your life with Birdees easier, send an email to [email protected]. SUPPORT & FEEDBACK I'm looking forward to your review in the App Store. You can leave me short feedback right inside the App Store. For all other questions, problems and suggestions send me an email to [email protected]. FEATURES - Import birthdays from your contacts - Manage further birthdays independently - Hide and show imported birthdays - Synchronize birthdays across multiple devices over iCloud - Open contact details directly from inside Birdees - Show a list with birthdays of the current year or continuously - Get detailed information about birthdays - Set flexible birthday reminders - Group birthdays according to your needs - See upcoming birthdays in the Today widget - Choose between pink and blue (light or dark) theme

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.
