StrikeMaster transforms your iPhone into a mobile metal analysis lab. The app employs the Archimedes water displacement method to calculate density with lab-grade precision. Weigh your metal dry, then submerged in water, and the density calculator instantly matches results against a reference table of 10 common metals including copper at 8.96 g/cm³, aluminum at 2.70 g/cm³, and stainless steel at 8.00 g/cm³.
The Metal Lab suite includes a step-by-step magnet test that narrows ferrous versus non-ferrous identification through a series of yes-no questions, and a spark test visual guide showing color patterns, length measurements, and fork characteristics for carbon steel, stainless, cast iron, and other alloys. Each entry records weight, grade, source location, and photos for complete traceability.
Profit calculators run real-time scenarios before you load the truck. The trip cost module factors distance, fuel consumption rate in L/100km, and fuel price against expected revenue to display net profit. The wire stripping advisor compares selling copper cable as-is versus stripped by calculating time value, recovery percentage, and price differential. Volume-to-weight converters handle pipes, boxes, and cylinders using metal-specific density data to estimate weight from dimensions.
Add entries with weight in kg, lbs, or tons, select metal type from copper, aluminum, brass, ferrous, and stainless categories, assign grade tags like A1, Mix, Shine, or Dirty, attach location and source notes, and store photos directly in each record. Filter by date or metal type to review history and reuse favorite collection spots.
Run density calculations using dry weight and water weight inputs to match against reference densities for 10 metals. Follow the magnet test decision tree to determine ferrous properties. Consult the spark test guide with color descriptions for carbon steel yellow-white 60-70 inch sparks, stainless orange-red 20-30 inch streams, and cast iron short 10-20 inch bursts. Access the metal encyclopedia for melting points, magnetism data, and common sources.
Use the price estimator to enter weight and price per kg with saved yard presets to see instant revenue projections. Combine multiple metal types in the batch sum tool for mixed loads. Calculate trip cost by entering one-way distance, fuel consumption slider adjustment, fuel price per liter, and expected revenue to view trip cost versus net profit in real time.
Compare selling insulated copper cable as-is versus stripped by inputting cable weight, as-is price, stripped price, and estimated stripping time. The advisor calculates copper recovery percentage, time value, and displays whether stripping adds profit or wastes labor. Adjust cable diameter and insulation thickness sliders to model different wire gauges.
Select shape type from pipe, box, or cylinder options, enter dimensions in millimeters or inches, choose metal from the dropdown with density automatically applied, and receive weight output in kilograms. Handles hollow pipe calculations with inner and outer diameter inputs. Useful for estimating scrap weight before cutting or loading.
View monthly revenue trends in chart format, analyze profit distribution by metal type with color-coded breakdowns, set monthly collection goals with progress tracking, and export full reports to PDF including entry details, total weights, revenue summaries, and timestamps for tax records or yard negotiations.
