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
Follometry analyses your Instagram export directly on your device — no login, no account, your data stays on your device. NO LOGIN. NO ACCOUNT. NO PASSWORD. Most follower-check apps ask for your Instagram login or require you to register on their platform. Follometry needs none of that. The app only analyses the official export file that Instagram makes available to every user. No rule violations, no risk to your account. NON-FOLLOWERS See at a glance who you follow but who isn't following you back. Tap any account to open it directly in Instagram. Deactivated accounts or celebrities can be hidden permanently — one at a time by swiping, or several at once using multi-select. SNAPSHOT COMPARISON Load two Instagram exports from different points in time and see exactly what changed: who unfollowed you during that period, and who started following you. The unfollow view is especially useful for spotting bots — accounts that follow, then quietly disappear days later. MORE FEATURES Permanently ignore accounts from the non-followers list and restore them any time. Export the full list as plain text and share it directly to Notes, WhatsApp, or any other app. HOW IT WORKS 1. Instagram app: Settings → Accounts Centre → Your information → Download your information 2. Select JSON format, choose only "Followers and following" 3. Receive the ZIP file by email and open it in Follometry 4. Done More info and a step-by-step guide at getfollometry.app

Hypothesis 1
Integrate push notifications and social sharing.
Assumption to check: Lack of user engagement features like reminders or community support
Validate with people who use this workflow before building.
Hypothesis 2
Allow users to customize cycle lengths and add custom event types.
Assumption to check: Limited customization options for cycles and events
Validate with people who use this workflow before building.
Hypothesis 3
Implement charts to visualize cycle patterns.
Assumption to check: No data visualization for tracking trends over time
Validate with people who use this workflow before building.
Hypothesis 4
Enable iCloud sync for user data.
Assumption to check: Absence of backup or sync options
Validate with people who use this workflow before building.
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.
