Survey and draft — all by yourself. The site inspection app built for architects. ■ No more two-person tape measure walks FieldSketch uses your iPhone's motion sensors to measure distances as you walk. Aim the crosshair, tap to drop a pin. One site in 10 minutes, calibration included. No need to book an assistant. ■ CAD drawings straight from the field Export as DXF (R12) — opens directly in Jw_cad and other CAD software. Register a cadastral PDF in advance and the app automatically merges it with your field data. ■ Everything captured in one place Photos are taken automatically at each measurement point. Record video while you measure to document the site. Points, distances, and photos compiled into a PDF report — ready for same-day delivery. ■ 4 simple steps Calibration → Site boundary → Surroundings (gutters, roads) → Landmarks (manholes, etc.). Guided workflow. Easy to undo and redo. ■ Accuracy Approx. 3 cm error over 30 m (verified on device). No LiDAR required — works on any iPhone. A 3-point calibration at the start improves accuracy further. ※ Designed for site reconnaissance and planning. Not intended for legal boundary surveys. ■ Pricing Measurement, photos, video, and PDF export are free forever. CAD (DXF) and CSV export require a Premium plan (monthly / lifetime).
