WiFi Plan maps your home's WiFi on iPhone and iPad: scan or draw your floor plan, walk round measuring real speeds, and see where the signal is strong and where it struggles on a heat map. Routers, extenders and mesh, predicted coverage, before and after runs, the garden too, and exports to PDF, DXF, IFC and USDZ. No account, nothing sent to us.
Dev Army Knife puts 101 developer tools on your iPhone and iPad: editors, converters, SSH, API testing, image tools and references. All on device, no accounts.
