Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Rep Jam Gig is the working notebook for musicians — singers and instrumentalists. Your repertoire in the keys you do it in, every jam and gig logged, set lists that build themselves, a calendar of what's coming, and a directory of everyone you've played with. It's one app, not five. Log a jam and the songs you called file themselves into your repertoire; the players you name build themselves into a directory. What you do on a Tuesday night makes the app more useful by Friday. WHAT IT TRACKS • Repertoire — every song you know, sorted Performance Ready / In Progress / Want to Learn, with your key, the credits and any notes you need at the stand; searchable and filterable by genre • Jams — log who you played with and what you played, grouped by night • Gigs & Set Lists — build set lists from your ready repertoire, with a tempo-aware builder, and save what you actually played • Calendar — plan the jam sessions you mean to go to, with repeats like "every Wednesday" or "the third Monday of the month". Star the ones you care about, search them, and log one as a jam in a tap. Import any calendar's .ics file • Musicians — a running directory of everyone you've played with, built automatically from your jam and gig entries, with instruments and Instagram handles • Charts — keep the lead sheet with the tune: a PDF, a photo or a scan of the page, or a MusicXML file from your notation software, opened full screen from the song Songs you perform that aren't already in your repertoire file themselves under In Progress — with composer, lyricist and year filled in from the built-in songbook of 2,500+ standards — so nothing falls through the cracks. BULK IMPORT AND EXPORT Already have your setlist in a spreadsheet? Download one CSV template covering your whole library — repertoire, musicians, jams and gigs — fill it in with any spreadsheet app, and import it back in. Songs and musicians already on file are matched by name and merged, never duplicated or overwritten with blanks, so re-importing the same file is always safe. Export All Data writes everything back out, for a backup or for moving to a new device without iCloud. Once you have charts, it's one zip — the CSV, your calendar and every chart file. Import it and the charts land back on their songs; the Calendar tab takes the same zip for your sessions. CHARTS THAT PLAY Attach a lead sheet to any song and open it full screen: each page fits the screen, swipe between pages, pinch in on small print. Add it on the song's own page from Files or Photos, or scan the paper with your camera and the pages become one PDF; the camera is asked for only when you scan. Or send one over from Files, AirDrop or a scanner app and choose the song it belongs to. Share a chart on from the chart itself. A MusicXML lead sheet — the export every notation program writes — opens as notation rather than a picture of one, and plays. Melody, chords, or both, on a recorded piano, with a line travelling along the music. It plays in your key rather than the one the file was written in. Tap out the tempo, type it, nudge it or drag it; send the tune round as many times as you want; start with an intro of the last four or eight bars. Each song remembers how you last played it. The piano is inside the app, so a chart plays with no signal at all. Playing fetches nothing and sends nothing. SYNC ACROSS DEVICES Your repertoire — charts included — follows you from iPhone to iPad through your own iCloud account, and it is yours: nothing goes to us, and we run no server for it to go to. Turn iCloud off for Rep Jam Gig and iOS takes the synced library off that device; it stays in iCloud and returns when you turn it back on. DESIGN A dark, uncluttered interface with serif type throughout, built to be read quickly at a stand or a bar. Rep Jam Gig starts empty: no sample data to delete, nothing to configure. Just start adding what you actually play.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Add calendar view, reminders, and collaboration tools.

Assumption to check: Limited features for organizing gigs and rehearsals

Validate with people who use this workflow before building.

Hypothesis 2

Implement push notifications for reminders.

Assumption to check: No notifications for upcoming gigs or rehearsals

Validate with people who use this workflow before building.

Hypothesis 3

Allow users to customize gig templates and locations.

Assumption to check: Lack of customization options for gig settings

Validate with people who use this workflow before building.

Hypothesis 4

Integrate calendar sync with Google Calendar or Apple Calendar.

Assumption to check: No option to sync with external calendars

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.
