Why some apps are Android-only
The trade calculators (deck, fence, drywall, insulation, tile, sod and gravel) are on Google Play only. Roofing Calculator & Estimator bundles them from version 1.7 on both Android and iPhone, so on iPhone they live inside the Roofing app instead of shipping as separate apps.
How we pick what to build
We build what people already search for on our websites and keep the apps small, fast and offline where possible. Read more in why we don't do subscriptions, or browse the full lineup, including web tools, on the All Apps page.
