## What is OptionProof 3D?

Catch missing custom-order specs before you waste a print.

OptionProof 3D is a local checklist for household FDM sellers who take name-plate, keychain, or colorway custom orders. Build a reusable template with text, number, and single-choice fields. Enter an anonymous order alias, see missing or conflicting values immediately, and share a customer-safe one-page PDF.

This app stores only what you type on this iPhone. It does not connect to Etsy or Shopify. It does not save customer names, addresses, emails, phone numbers, or payment information. It is not an order, invoice, or signature system.

Free: 3 templates, 3 proofs, and 3 PDF exports.
Unlock: unlimited templates, proofs, and exports.

## Pricing and in-app purchases

Base price: Free.

**One-time purchases**

| Purchase | Price | Type |

| Lifetime Unlock | $9.99 | one-time |
