BUILT FOR THE JOBSITE

• Works offline. No signal in a basement or mechanical room? Every calculator still runs — the code tables live on your phone.
• Shows its work. Each result displays the formula and the standard behind it, so you can defend the number to an inspector.
• Imperial or metric in one tap, applied across every calculator.
• Prices the job as you go. Set your material costs once and FieldDojo estimates the total with every calculation.
• Made for gloves and sunlight. Big tap targets, high contrast, readable on a roof at noon.
• No ads. Your calculations stay on your device unless you turn on cloud backup.
