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.

Meet an alarm app that knows when to get out of the way. Entropy Alarm was built by a developer with ADHD who wanted to create an alarm app for those who use alarms when a calendar or reminder app won't do. Entropy Alarm creates alarms that show up when you need them and clear themselves from your list, automatically, when you no longer need them! Entropy Alarm is a different kind of alarm clock, built around three alarm types so your list stays honest. Set something once and let it disappear. Repeat on a schedule until a date you choose. Or keep a routine that stays put until you delete it. Three alarm types: * Burner: a one-time alarm that deletes itself after you stop it * Frozen: a repeating alarm with a thaw date. It fires through that last day, then burns away * Crystallized: a permanent routine that repeats until you delete it Travel and time off: * Follow me keeps the same local time when you travel * Stay put keeps the alarm in its home time zone Alarms that ring only when you want or need them to * Skip holidays on Frozen and Crystallized alarms, with calendars for the US, UK, Canada, Australia, Germany, Spain, Mexico, and France * Add your own days off, like PTO or a birthday Sounds and extras: * Choose from built-in ringtones or import your own audio from Files * Snooze from 1 to 30 minutes, or turn it off * Live Activities show your snooze countdown on the Lock Screen and Dynamic Island * A Home Screen widget keeps your next alarm in sight * Siri, Shortcuts, and Control Center can start a new Burner, Frozen, or Crystallized alarm Make it yours: * Name alarms and give them an emoji * Pick a look: Basic, Bold, Dramatic, Frosted, or Burnout * Light, dark, or follow your device theme * 12-hour or 24-hour time Keep track: * Logs show what burned, thawed, snoozed, and fired * Stats and achievements if you like a little extra spark Entropy Alarm uses Apple's AlarmKit so alarms can still ring through Focus and Silent mode, the same way Clock alarms do. A short welcome walkthrough explains the three alarm types, and you can replay it anytime from the Profile tab. No ads. No in-app purchases. Your alarms stay on locally your device.

Hypothesis 1
Assumption to check: Limited customization for alarm sounds and settings
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: No snooze functionality for alarms
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: Lack of recurring alarm options
Validate with people who use this workflow before building.
Hypothesis 4
Assumption to check: User interface may feel cluttered
Validate with people who use this workflow before building.
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.
