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

Stop guessing whether a card is worth grading. Take two photos to predict its grade and the odds of each outcome, see detected damage and measured centering, and estimate your profit after grading and selling fees. Evo was trained using cards from real cracked slabs. Use it to pre-grade cards, track submissions, track your gem rate, find potential grading opportunities, and monitor your collection value. TRAINED ON REAL SLABS We bought slabs graded by PSA, TAG, and CGC and cracked them open to train Evo’s model. Evo learns from cards that received real professional grades, helping it connect visible damage, centering, and condition with grading outcomes. Our current slab data covers PSA, TAG, and CGC grades 6–10, as well as CGC Pristine 10. SEE THE DAMAGE Any AI grading app can give you a number, but we believe it is important to explain why. Evo marks detected damage directly on your card and measures its centering. You see the flaws, not just a score, so you can better understand why a card may land at a 9 instead of a 10. KNOW YOUR PROFIT Every grade includes an estimated profit breakdown after grading and selling fees, based on recent eBay sold data. Compare the potential outcomes before you submit. GRADE FOR PROFIT Grading Plays surfaces cards with strong potential grading returns, ranked by estimated Grade 10 ROI. Use it to find opportunities at shows or online. TRACK EVERY SUBMISSION Build your grading piles, send your cards off, and track your gem rate, estimated profit, and results in one place. PRICE CARDS AND SEALED PRODUCTS Look up market values for cards and sealed products, or see the combined value of cards from a particular Pokémon, set, or illustrator. WATCH YOUR COLLECTION GROW Track your sets, illustrators, and total collection value over time, and see your top movers. Performance View shows how your collection is doing without requiring you to enter what you paid. COMPLETE YOUR COLLECTION GOALS Create a list for whatever you are chasing. Whether it is an English Gengar master set or every card illustrated by Shinji Kanda, Evo helps you track your progress. Evo helps you: ► Predict a grade from two photos ► See damage and centering marked on your card ► Estimate profit before you submit ► Find potential cards to grade for profit ► Track submissions and your gem rate ► Price cards, sets, sealed products, and illustrators ► Pre-grade a card before you buy it ► Watch your collection grow ► Complete your collection goals Evo is not affiliated with, sponsored by, or endorsed by Nintendo, The Pokémon Company, PSA, CGC, BGS, or TAG. Evo grades and financial calculations are estimates, not guarantees. Results may vary based on card condition, photo quality, market prices, grading outcomes, and fees. Make sure your grading photos are clear and well lit.

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.
