EngineerTact vs Glyphmint

EngineerTact is an offline field toolkit for engineers, land surveyors, RF technicians, and field operators across all domains — land, sea, and air. KEY FEATURES: • WGS84 Geodetic Coordinate Conversion — Convert between Geodetic (Lat/Lon/Alt) and ECEF (X/Y/Z) using the Bowring iterative algorithm. Real-time ENU Local Tangent Plane target tracking with bearing and range. • RF & Radar Calculator — Compute Free Space Path Loss (FSPL), Radar Line of Sight (4/3-Earth model), first Fresnel Zone radius, and signal wavelength. All calculations run on-device. • Mission Brief Planner — Build complete field mission briefs with route distance (Haversine), bearing in degrees and NATO mils, estimated time of arrival, and RF link margin. Save and reload briefs on-device. • Aerospace & Maritime Converter — Convert speed (knots, km/h, m/s, Mach), altitude (ft, m, FL), pressure (hPa, inHg, psi), and ISA atmospheric parameters with full unit coverage. • Number Base & Data Converter — Convert between decimal, hexadecimal, binary, and octal. IEEE 754 float analysis. Bit-width calculator. • Formulas & Reference — Full mathematical reference for FSPL, WGS84 geodesy, Haversine, radar horizon, Fresnel zone, and NATO unit standards. All calculations are performed entirely on-device. No network connection, no account, no tracking, no ads. Designed and engineered by Fırat Bozkaya.

Label Studio builds reusable QR label runs and checks every code against its intended payload in the finished PDF before export. HOW IT WORKS 1. Open Labels. Name the run, choose Letter or A4, then create a numbered sequence or add custom captions and exact QR payloads. 2. Edit individual labels and copy counts. Save the run locally for reuse. Build the verified PDF. 3. Inspect the label sheet and share the PDF with its proof manifest. Print one test sheet at actual size and test it with the intended scanner. Create, styling, scan-and-verify, history, batch generation, print sizing, Preflight Lab and the reference kit remain available. Letter/A4 sheets use black vector modules and four-module quiet zones. Run storage preserves unreadable files and reports save failures. WHAT TO KNOW Eight labels per page with generic cut guides, not adhesive-stock templates. Up to 80 entries, 20 copies per entry and 160 labels per run. Payloads are limited to 512 UTF-8 bytes, and overly dense codes are refused. Verification decodes the final PDF at 144 DPI; it does not test physical prints or link destinations. PDFs and manifests include the entered payloads, including any passwords or contact details. iPhone and iPad.
