Common questions
I bought Pro. How do I get it on a new phone?
Open SiteSum, go to Settings and tap Restore purchases, signed in with the same Apple ID. Pro Family is shared automatically with everyone in your Family Sharing group.
Does it need a signal?
No. Every calculation, builder and export works offline. Pro bought once never needs to check in. A monthly Pro checks with the App Store when it renews and keeps working offline for three days past its renewal date.
How do I cancel Pro monthly?
In the iPhone Settings app: tap your name, then Subscriptions, then SiteSum. Or from SiteSum’s Settings, tap Manage subscription.
Why does an answer start with ≈?
The exact answer falls between sixteenths (or whatever precision you chose), so it was rounded to the nearest mark. Pro can show 1/32" and 1/64".
How do I use Siri?
Say “Calculate with SiteSum”, then the sum, the way you’d say it on site: “14 feet 3 and a half minus 2 feet 7 and five eighths.” It also works as the Calculate action in Shortcuts.
Where are the widgets?
Touch and hold the Home Screen or Lock Screen, tap Edit or Customize, then add SiteSum. The Lock Screen widget and the Control Center button are free; the Home Screen widget is Pro.
Are the stair and baluster limits code-approved?
They are reference defaults, and the app says so. Check your local code: the inspector has the last word.
Prices
SiteSum is free to download. Pro is $24.99 once, Pro Family $34.99 once for up to six people, or Pro monthly $4.99 a month. US prices; the App Store shows yours. The terms cover renewals and refunds.
