Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.
First kit free with a verified email
Combine features and design from your favorite apps.

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.

LOC8 is a fast GPS, geolocation, and location app built to answer one simple question: Where am I? Open LOC8 to instantly see your current location, GPS location, street address, nearest cross street, county, GPS coordinate, compass heading, elevation, live GPS accuracy, and what3words location code. Whether you need my location, map location, live GPS information, or exact coordinates, LOC8 gives you the details in seconds.

Built with safety, family safety, and emergency use cases in mind, LOC8 can help when you need a safety location, SOS location, or fast GPS location reference. Law enforcement, fire and EMS, search and rescue teams, field workers, and outdoor professionals can quickly access coordinates and location details. MULTIPLE GPS COORDINATE FORMATS View, copy, and share GPS coordinates in: • Decimal Degrees (DD) • Degrees Minutes Seconds (DMS) • Degrees Decimal Minutes (DDM) • Universal Transverse Mercator (UTM) • MGRS / milGPS Share location details including your address, GPS coordinate, compass heading, elevation, or what3words location code. Whether you use GPS, geolocation, milGPS, or another coordinate format, LOC8 helps you find GPS information fast. SAVE LOCATIONS AND WAYPOINTS Save important locations and waypoints, including trailheads, campsites, parking spots, work sites, and meeting locations. Search a saved location or enter a location code, then use live distance and compass direction to find location details and navigate back. Need to return to a saved place? LOC8 can show the destination on a map and enter tracking mode, giving you live GPS distance, compass direction, and navigation guidance as you move. GARMIN WATCH GPS LOCATION COMPANION Use LOC8 on the Garmin Watch to check GPS location details from your wrist, including current location, address, GPS coordinates, compass heading, and signal accuracy. Built for quick live GPS and geolocation checks when a map is not practical. DESIGNED FOR FAST LOCATION ACCESS • Current location, street address, county, and nearest cross street • GPS coordinates in DD, DMS, DDM, and MGRS / milGPS • Compass heading, elevation, and live GPS accuracy • what3words location code for location share and share location needs • Saved locations, places, and waypoints • Map location search and GPS location lookup • Live distance and compass direction to a saved location • Fast geolocation, my location, and current location lookup • Find location details and find GPS information quickly • Emergency, SOS location, family safety, and safety location support LOC8 is not turn-by-turn navigation and does not replace Find My iPhone. It is a fast GPS, geolocation, location, and coordinate reference tool for moments when you need to know exactly where you are, check my location, find location details, view GPS coordinates, navigate back to a saved waypoint, or share location information. PRIVACY LOC8 only uses location while the app is open. It does not create accounts, user profiles, live location tracking, or location history. Saved locations remain on your device. When LOC8 resolves a GPS coordinate into an address or cross street, that coordinate may be used with Apple location services and LOC8's secured backend for that lookup. Monthly: $7.95 Lifetime: $39.95 (one-time) You can turn off auto-renewal anytime in your Account Settings. A paid subscription or a one time purchase is required to use LOC8.

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.
