Fieldline

Bring your field measurements, calculations and technical records together in one engineering workspace. FIELDLINE helps you organize the complete task: create a project, record readings, connect calculations, add observations, sketch an assembly and generate a technical PDF report. Your project data stays connected from the first measurement to the final document. PROJECTS THAT KEEP YOUR WORK TOGETHER Organize inspections, maintenance work and site tasks by project. Keep measurements, calculations, notes, checklists, sketches and reports together, with project status and recent activity at a glance. MEASUREMENT RECORDS WITH CONTEXT Manually enter readings with a value, unit, location, group, timestamp and note. Browse records by group or timeline, edit or duplicate readings, and assign Normal, Warning, Check or Verified status. Add optional limits to flag values outside your chosen range. CONNECTED CALCULATION CANVAS Use 37 built-in formulas for geometry, mechanical, electrical, materials and construction tasks. Enter parameters manually, link compatible measurements or use a previous calculation as an input. Linked results update with their source records. Create and save your own formulas with named variables and units. UNIT LAB AND SMART INPUT Convert across 16 categories, including length, area, volume, mass, pressure, temperature, force, torque, energy, power, speed, density, flow, voltage, current and resistance. Parse typed values such as 42.6mm or 0.82MPa, and simple area expressions such as 3.2m × 4.5m. FIELD NOTES AND INSPECTIONS Attach observations to the measurements they describe. Start with general, electrical, mechanical, HVAC or workshop inspection templates, or create a custom checklist. Record Pass, Fail, N/A or Pending results and add notes to individual items. ANNOTATED FIELD SKETCHES Draw lines, arrows, rectangles and circles. Add text and dimensions, link labels to measurement records, edit elements and use undo and redo. Export your drawing as an image or include it in a report. TECHNICAL REPORTS, READY TO SHARE Choose the project sections to include and generate a multi-page PDF containing readings, calculation inputs and results, notes, inspection records and sketches. Preview and share your report. Saved PDFs preserve the project at the time they were generated. REFERENCE AND SEARCH Look up typical material densities, constants, formulas, units and engineering symbols. Search project records by names, values and annotations to find related data. WORK OFFLINE Core features work without an internet connection or account. Records are saved on your device. Export a workspace backup, including generated PDFs, and import it without replacing existing projects. FIELDLINE uses an English-language interface. Measurement values are entered manually; the app does not measure physical dimensions with phone sensors. Calculations, thresholds and reference values are engineering aids. Verify inputs and applicable project standards before making final design decisions.
