HARLO SurveySuite — Field COGO + FS/PS Exam Prep

Built by surveyors, for surveyors. HARLO SurveySuite is the professional-grade mobile toolkit that combines field-ready coordinate geometry calculations with the most comprehensive FS and PS licensure exam preparation available on iOS.
Whether you’re running a traverse on a property corner, prepping for the Fundamentals of Surveying exam, or studying for the Principles and Practice of Surveying, SurveySuite delivers the precision, depth, and reliability the profession demands.

FIELD COGO TOOLS

Solve real survey problems in real time, anywhere:

• Traverse computations — single and multi-leg traverses with closure analysis, angle balancing, and coordinate adjustment
• Inverse and forward calculations — distances, bearings, and azimuths between any two points
• Point-on-line and point-to-line solutions
• Curve calculations — radius, deflection, chord, arc length, tangent, and external distance
• Intersection routines — bearing-bearing, bearing-distance, distance-distance
• Area computations — coordinate method with closed polygon validation
• Trigonometric leveling — vertical angle reductions with curvature and refraction corrections
• Differential leveling worksheets with rod intermediate sights
• Coordinate transformations — local to grid, NAD83 conversions, scale factor adjustments
• Bearing and azimuth conversions — quadrant, decimal degrees, DMS
Every calculation is verified against published surveying principles. Show your work with full computation breakdowns — perfect for field notes, deliverables, and learning.

FS AND PS EXAM PREP

Pass the NCEES Fundamentals of Surveying and Principles and Practice of Surveying exams with confidence:

• Comprehensive question banks aligned to the current NCEES exam specifications
• Boundary law fundamentals — public land survey system, metes and bounds, riparian rights, adverse possession
• Geodesy — geoid, ellipsoid, orthometric and ellipsoidal heights, datum transformations
• Photogrammetry, remote sensing, and GIS basics
• Statistics, error analysis, and least squares adjustment
• Legal principles, ethics, and professional practice
• Detailed answer explanations — every question shows the why, not just the what
• Performance tracking by topic — identify weak areas before exam day
• Timed practice exams that mirror real testing conditions
