Roof pitch, rafters, stairs, areas, volumes and mitre angles. Choose a calculator, enter your measurements and work in the units that suit the job.

Keep notes, calculations, materials and attachments with the work they belong to. Break the project into phases and actions so the next step stays in sight.

Refresh a technique before you start. Practical lessons cover measuring, set-out, framing, roofing and estimating, with tool guides close at hand.

Use your iPhone for a quick check. Open your iPad when it is time to work through the details. See the current phase, review the next actions and keep your notes alongside the plan.
