Support

The fastest way to get help, report a bug or suggest a feature is to email us. The button opens your email app with your platform and app version filled in — nothing is sent until you choose to send it.

When reporting a bug, please include

• Your device and OS version (e.g. iPhone 15 Pro, iOS 18.4)
• App version: 1.0 (web)
• The screen or calculator you were using
• What you expected vs. what happened
• Steps to reproduce, if you know them

Common questions

A calculator gave a different result to mine

Calculators are indicative and Building Regulations guidance applies to England only — see the Terms of Use. Always verify against the current Approved Document, standard or professional advice. If you believe a formula is wrong, email us the inputs you used and we'll investigate.

The salary data looks out of date

Salary benchmarks reflect published sources at the date shown in the app and are reviewed periodically. If you know of a more recent published source, send it across.

Does the app work offline?

Core reference tools work offline. Purchases, restoring access and external links require an internet connection.

Restoring an existing Pro purchase

1. Make sure you're signed in with the Apple ID you used to buy Pro and are online.
2. Open ArchBuddy and go to the ArchBuddy Pro screen (Settings → Upgrade to Pro).
3. Tap Restore Purchases. Pro unlocks as soon as your purchase is confirmed.

Refunds

ArchBuddy is free to use, with optional Pro features unlocked by a one-time in-app purchase at the price shown in the app. Purchases and refunds are handled by Apple. To request a refund, visit reportaproblem.apple.com.
