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

GVX is the ballistic solver for sport, precision and long-range shooting, independently conceived and developed by Giuseppe Valtorta, founder of Victrix Armaments. It is not built on theory alone: it is validated with real measurements, Doppler radar data and complex measuring systems, using the same method with which Victrix rifles are designed and tested. TRAJECTORY AND FIRING SOLUTION • Full trajectory with drop, wind drift, spin drift, aerodynamic jump, Coriolis and Eötvös effect • Corrections in Mil or MOA, as turret clicks and as holdover on the reticle, with the reticle library • Target output, range card, drop tables, moving target and milling • MRD (most recommended zero), Speed Drop Factor and maximum range • Dashboard: elevation, windage and shot data on a single screen, with a night theme too ATMOSPHERE AND WIND • Temperature, pressure, humidity and altitude, with muzzle velocity following powder temperature • Single wind, wind zones or wind reading points along the trajectory • One-tap weather from the internet when a connection is available AMMUNITION AND BULLETS • Catalogue of over 4,000 factory loads and bullet library with G1 and G7 coefficients • Gyroscopic stability (Sg) of the bullet in your barrel YOUR DATA • Rifles, loads, positions and settings saved by name • Import of profiles from other apps and of bullet libraries, export of results • Print and PDF of every page • Italian and English; metric or imperial units chosen quantity by quantity • All calculations stay on the device and work offline GVX PRO — ONE-TIME IN-APP UPGRADE • Predictive hit-probability analysis • Loophole, the precision-match exercise • Real ballistic coefficient from radar data and measured drag curve • Ballistic coefficient from your own shots • Cant analysis • Import from Garmin Xero and Labradar chronographs • Angle of site measurement with the phone • Share data with a fellow shooter: the .gvx file opens directly in GVX • Apple Watch: elevation, windage and cant on your wrist, updated automatically Complete user manual inside the app. GVX is a calculation tool for sport, precision and long-range shooting. Results must always be verified on the range: the shooter remains responsible for the use of the firearm, in compliance with the laws of their country.

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.

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.

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.
