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

CollX (pronounced "collects") answers the question every collector has: "What's it worth?" The app lets you scan virtually any sports, trading card game, or non-sport card! That includes baseball, basketball, football, wrestling, hockey, soccer, MMA, boxing, golf, tennis— as well as TCG cards like Pokemon, Magic, Yu-Gi-Oh!, Flesh & Blood, One Piece, Disney Lorcana, and even Non-Sport categories like Garbage Pail Kids, Marvel, and Star Wars. CollX will instantly identify the card and get the average market value. Once you've scanned your cards, add them to your collection and track your portfolio. You can also buy and sell via the CollX marketplace, where you can purchase cards with a credit card, get shipping and tracking, and earn cash selling your cards to other collectors. Turn the hobby into your side hustle! COLLX SPORTS AND TCG SCANNER CollX's visual search technology instantly recognizes and matches against a database of 20+ million cards. After identifying the best match, you'll get the current average market price for the card. Our deep-learning models were created by a team with 10+ years experience developing image recognition technology. In addition to being able to match most RAW cards, CollX will also identify graded cards, as well as parallel and reprint versions of cards. BUY AND SELL The CollX marketplace is the fastest growing place to buy and sell cards. Use Deals to bundle multiple cards and make an offer to the Seller. As a Seller, you can utilize several shipping options, including CollX Envelope, where you'll get tracked shipping for as little as $0.75! Other Seller Tools include the ability to set a bulk discount, accept offers, and vacation mode. Cards bought through the CollX marketplace are covered by CollX Protect, where payments are only released when the cards arrive at the Buyer, giving peace of mind to both parties in a deal. COLLX AI The first AI built specifically for the trading card hobby, CollX AI provides insights on cards, coaching tips on how to do everything from negotiate to ship, and even can assist in helping sell your cards faster. GO PRO CollX Pro is a monthly subscription tier on CollX offering several power-user features, including: - Unlimited Collection Size - $10 Monthly Credit on CollX Marketplace - Featured Listings - Access to CollX AI - EasyPrice (dynamic repricing) - Export Collection as CSV spreadsheet - Printable Checklists And much much more! CollX Pro is $10/month or $100/year. GET HISTORICAL PRICING CollX uses millions of historical auction prices to calculate a card's average value. As you add cards to your collection, you'll see your overall portfolio value grow. As your cards rise or fall in value, CollX helps you track both individual card values and your overall portfolio value. No more wondering what your Pokémon card value is! BUILD YOUR CARD COLLECTION Create and keep track of your card values. View your collection as a grid, list, or as sets. You can also filter and sort your cards by a variety of criteria — value, date added, year, team, etc. Export as spreadsheet and generate set checklists with CollX Pro. SEARCH CARDS Search 20+ million cards in our database or the millions of CollX user cards for sale. Save your favorite searches to get email, push or in-app notifications when those cards are added for sale. When you click on links to various merchants on this site and make a purchase, this can result in this app earning a commission. Affiliate programs include, but are not limited to, the eBay Partner Network. Read our Terms of Use at https://www.collx.app/terms
