Eyebrow: Construction takeoff · Maintenance of traffic
Measure quantities and draft maintenance-of-traffic (MOT) layouts in one Mac workspace, starting with your PDF plans.
Available now on the Mac App Store. Requires macOS 14 or newer.
Turn drawings into quantities. Calibrate against a known distance, then create linear, area, and count takeoffs. Save an editable project and export quantities or marked-up PDFs.
Build out the traffic plan. Place MOT and temporary traffic-control symbols (signs, cones, drums, barricades, arrow boards, pedestrian control), notes, and hatched work areas alongside your plans. Review each layout against the requirements of your project and reviewing authority.
One set of tools. Two billing options.
Free download. $9.99/month or $79.99/year, billed upfront annually. Both plans include the same takeoff and MOT tools. An active subscription is required to use the editor.
U.S. App Store pricing; Apple displays the final price at purchase. Subscriptions renew automatically unless canceled through your Apple Account. Optional AI requires your own API account; cloud hosting is separate.
