GOLD - CALCULATOR

GOLD brings calculation, camera measuring and project planning together in a beautifully crafted calculator.

CALCULATE WITH REAL UNITS
Work with expressions, brackets, percentages and unit conversions. Keep calculation history and reuse results in your next idea.

SEE YOUR SPACE
Bring length, width and height into a live floor plan. Explore area, volume and material costs. Adjust a dimension and see the result change. AR measuring helps estimate distances using two points in the camera view.

OPTIONAL UPGRADES
GOLD Pro is an auto-renewing subscription for multiple spaces, saved comparisons and PDF estimates.
Auto Object Capture is a separate one-time purchase for guided 3D scanning, on-device reconstruction, saved models and USDZ sharing. It requires a supported iPhone with LiDAR and on-device reconstruction support; purchase availability is checked on your device.
All-Gold Face is a separate one-time purchase for a polished gold calculator face and gold keys. It changes appearance only.

YOUR GOLD EDITION
Connect to the internet when you first open GOLD. Your edition number is assigned automatically when verified registration completes. Offline use can delay registration while other editions are issued. Lower numbers identify earlier registrations, not guaranteed monetary value or exact App Store download order. Series II is a new registration series, separate from the original GOLD register. Earlier editions require historical verification.

NEARBY CHAT
Choose a username and connect directly with another nearby GOLD user using a pairing code and host approval. A signed edition record can appear beside your name; it does not verify the other person's identity. Nearby chat needs two phones and local network permission; it has no global inbox or background delivery.

PRIVACY AND PRACTICAL DETAILS
Projects, calculations and capture files are stored on your device. There are no ads or analytics SDKs. Edition registration requires an online registry. Measurements and reconstructed dimensions are estimates; verify them before ordering materials or doing precision work.

Subscriptions renew automatically unless cancelled. Manage or cancel in your Apple Account settings. The purchase screen shows the localized price and billing period.
