## Description

The only calculator app with dovetail spacing, box joints, and wood movement. Fractions are native. No subscription.

Dead On is the woodworking calculator that thinks like a woodworker.

FRACTION CALCULATOR
Mixed fractions are first-class. Type 5-3/4 + 2-1/8 and get an instant answer in fractions — chain math with parentheses, down to 1/32. No decimal conversion, ever.

VOICE INPUT
Hands full of sawdust? Tap the mic and say "five and three quarters plus two and an eighth." Dead On writes 5-3/4 + 2-1/8.

SHOP MODE
Step-by-step cut guidance in giant shop-floor type. It reads each step and listens for "next" — eyes on the blade, not the phone.

18 TOOLS BUILT FOR THE SHOP
• Board feet with cost — know the bill before the register
• Lumber yield with waste factor
• Cut list optimizer and glue-up panels
• Miter and compound angles with live diagrams
• Dovetails, box joints, dados, mortise & tenon
• Shelf sag, drawer slides, pilot holes, taper, epoxy pour, wood weight, wood EMC

JOINERY WITH LAYOUT MARKS
The only woodworking app with built-in joinery math — and the diagrams are drawn from your numbers, with layout marks you can transfer straight to the board.

WOOD MOVEMENT
Select from 30 wood species and calculate seasonal dimensional change from USDA data. Know exactly how much your tabletop will move, and how much gap to leave.

PROJECT ORGANIZATION
Save calculations to projects. Your blanket chest keeps its board feet, dovetail spacing, and wood movement in one place — with seasonal movement reminders and iCloud sync.

BUILT FOR WOODWORKERS
• Fraction-native input and display
• Imperial and metric support
• 30-species North American wood database
• Apple Watch companion with a Digital Crown running total
• No subscription — pay once, own it forever
