Generating… usually about a minute.
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.

Requires iPhone Duo for automatic fold counting and open-session timing. Standard iPhone models and iPad do not provide the required folding triggers. One-time manual setup in Apple Shortcuts is required. Make every opening part of your story with Fold by Fold. • Track today's openings, your lifetime total, averages, milestones, and your busiest day on a stats-focused Overview. • Explore weekly, monthly, and yearly count charts, plus hourly and weekly completed-time charts. • Pair Opened and Closed automations to measure sessions, completed time, average session length, and your longest session. • Browse and filter counts and sessions by today, this week, this month, or all time. • Correct daily counts, add missed openings, or undo the latest eligible recorded opening. • Set an optional daily goal and choose optional local goal and milestone alerts. • Choose Classic or Dashboard separately for each Fold by Fold widget, with small, medium, and large sizes, plus Weekly activity and Daily goal widgets. • Preview both widget layouts inside the app using your history or labeled example data. Tap widgets to open relevant details. • Choose from 16 coordinated themes, including Lime, Magenta, Sand, and Midnight. • Adjust count size, contrast, and background decoration for readability. • Export daily history as CSV, save a JSON backup, and restore with a recovery copy. COUNTING AND TIMING HAVE SEPARATE SETUP Connect Record a Fold to an Opened-only shortcut. For automatic session timing, create a separate Closed-only shortcut containing Record a Close. Enable automatic running and allow running while locked for both. The five-step guide includes a physical test. Counting and Timing readiness reflect recorded signals, not an inspection of your automations. The troubleshooting guide helps with running timers, missing or doubled counts, and stale widgets. Support: [email protected]. No account, ads, subscription, analytics, or tracking. Counts and sessions stay on your device unless you export or share them. Support email sends nothing automatically. History starts when recording begins. Missing closes and earlier durations cannot be reconstructed. Current-session timers follow recorded actions, not verified physical posture. iOS controls automation execution and widget refresh timing. Goals and achievements are personal activity markers, not durability estimates. One-time paid app. No in-app purchases.

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.

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.
