Engineering Survey Calculator app analytics for September 2

The field companion for surveyors and civil engineers — 42 calculators, reference tables, and field tools in USCS and SI units. Engineering Survey Calculator covers the everyday math of land surveying, from tape corrections to vertical curves, with instant results, clearly stated formulas, and one-tap unit switching. CALCULATORS — grouped the way you work • Errors & Precision: standard deviation, probable errors, error of the mean, full observation sets • Taping Corrections: temperature, tension, sag, slope — individually or chained into one corrected length • Leveling: curvature & refraction, reciprocal leveling, relative accuracy orders • Traverse: latitudes & departures, misclosure, precision ratio, Bowditch adjustment, area by coordinates • Curves: horizontal circular curves (T, L, C, M, E, D) and parabolic vertical curves with high/low point • Stadia & Tacheometry, Earthwork volumes, Photogrammetry scales, and angle converters (DMS ⇄ decimal, azimuth ⇄ bearing) AUTO-FILL REFERENCE DATA Tap the magic wand to fill tape constants, instrument constants, camera focal lengths, and accuracy coefficients from built-in reference tables — no more hunting through handbooks. A dedicated Reference tab keeps all tables one tap away, in your chosen unit system. FIELD TOOLS • GPS field points: capture coordinates and elevation, then get distance and elevation difference between points • Clinometer: measure slope angles with your device's sensors • DMS quick-entry keyboard for angle inputs SAVE, ORGANIZE, SHARE Save any calculation to a project, attach field notes and photos, share results, and export a whole project as a PDF report. BUILT FOR THE FIELD • USCS and SI units everywhere, one tap apart • Formulas shown with every result • Favorites and search • Dark mode, iPhone and iPad (side-by-side split view) • Works fully offline • Available in English, German, Spanish, French, Italian, Dutch, Portuguese, and Chinese (Simplified) Questions or suggestions? contact.pugal.apps@gmail.com
