I paid for Pro but it’s locked

Open Settings → Restore purchases. Make sure you’re signed in to the same Apple ID or Google account you bought with. If it still doesn’t unlock, email us with the date of purchase.

How do I cancel my subscription?

• iPhone: Settings → your name → Subscriptions → Complete Calc → Cancel Subscription.
• Android: Google Play → your profile picture → Payments & subscriptions → Subscriptions → Complete Calc → Cancel.

Pro stays on until the end of the period you paid for. Cancel at least 24 hours before it renews to avoid the next charge. Cancelling during the 14-day free trial means you’re not charged.

Can I get a refund?

Refunds for App Store and Google Play purchases are handled by Apple and Google. iPhone: reportaproblem.apple.com. Android: request it in Google Play under your order history, or see Google Play’s refund page.

Does Pro work on my other phone or tablet?

Yes, on devices signed in to the same Apple ID (iPhone and iPad) or the same Google account (Android). Install the app and tap Restore purchases. A purchase on iPhone doesn’t carry over to Android, or the other way around.

A result looks wrong

Check the inputs and the assumptions under each calculator (waste %, sizes, coverage). If the math is still off, email us the inputs and what you expected and we’ll look into it. Results are estimates: always double-check before buying or building.
