Asphalt Calculator Support
We are happy to help. For anything not covered below, email info@appharbour.com and we will get back to you.
Getting started
Pick a calculator, enter your dimensions, and the results update as you type. The hot mix calculator gives tons, cubic yards, truckloads and material cost; adjust density, waste factor, truck capacity and price per ton to match your job and supplier.
My tonnage looks off
Check three settings first: the density (the 145 lb/ft3 default is typical hot mix; use the presets for binder course, millings, cold patch or gravel base), the depth (make sure it is compacted depth in the unit you intended), and the waste factor. A 10 percent waste factor adds 10 percent to the raw tonnage by design.
Units and metric
Switch between imperial (feet and inches, US tons) and metric (meters and millimeters, tonnes) in the app settings. All calculators follow the selected unit system.
Saved jobs and PDF export (Premium)
Multi-section jobs, saved jobs and PDF estimate export are Premium features. PDFs are generated on your device and shared through the iOS share sheet, so you can text or email an estimate straight from the job site. Saved jobs live only on your device: deleting the app deletes your saved jobs, and there is no cloud backup or account to restore them from.
Restoring purchases
If you reinstall the app or switch devices, open the paywall or settings and tap "Restore Purchases" to bring back your Premium subscription or Lifetime unlock. Make sure you are signed in with the same Apple ID you purchased with.
Managing your subscription
Subscriptions are billed through Apple, not by us. Manage or cancel anytime in your Apple ID subscription settings: open the iOS Settings app, tap your name, tap Subscriptions, then select Asphalt Calculator.
Cancel at least 24 hours before the end of the current period to avoid the next charge. The weekly plan includes a 3-day free trial; cancelling during the trial means you are never charged. The Lifetime option is a one-time purchase with nothing to renew or cancel.
Refunds are handled by Apple under App Store policy: request one at reportaproblem.apple.com.
Privacy
The app is 100% offline and collects no data at all: no account, no analytics, no ads, no tracking. See the Privacy Policy.
