Woodworker’s Toolbox

I built a woodworking app

I got tired of reaching for my phone to do the same calculations over and over in the shop. So I built Woodworker’s Toolbox — an iOS app with the tools I actually use. No subscription, no ads, works offline.

  • Board feet calculator
  • Fraction arithmetic
  • Drill bit + pilot hole guides
  • Wood species database with Janka hardness, shrinkage, and movement data
  • Wood hardness chart with lbf/kN toggle
  • Wood shrinkage chart with colour-coded stability ratings
  • Species expansion matcher for mixed-species joinery
  • Wood movement calculator
