RF Tools vs EngCalc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
RF Tools
This utility app helps engineers and students calculate and convert RF-specific values like impedance, wavelength, and return loss. It also includes a calculator for comparing RF cables and assemblies, and provides access to product catalogs and branch information.
- RF value conversion (impedance, wavelength, return loss)
- RF assembly calculator
- dB calculator
- Product catalog access
- Branch locator

The RF Tools App from HUBER+SUHNER AG is a useful tool, which shows the relation between RF specific values like impedance, wave length, return loss (VSWR) and signal delay including their conversion. On top of this, the RF Assembly Calculator provides an easy comparison of H+S RF cables and assemblies in different configurations and in different environments. It offers a straight access to technical specifications such as insertion loss and power rating. Above all, engineers and students will love this handy and helpful tool. Content Tools Reflection measurement (Return loss - VSWR) Frequency wavelength (Wavelength calculation) Signal delay (Signal delay - Dielectric constant - Velocity in % of speed of light) Impedance dimension (calculation of impedance of coaxial line) dB Calculator (dB Ratio / Watt - dBm) RF Assembly Calculator (comparison of up to three HUBER+SUHNER RF cables) Used formulas are explained in detail by meaningful pictures. Products Provides an overview of HUBER+SUHNER products such as cables, connectors, antennas, lightning protectors and passive components with the help of the product catalogues.

An engineering calculator that does not stop at basic arithmetic. EngCalc opens with a familiar, fast calculator - and behind it, fifteen professional modules for when the work gets serious. CAMERA SOLVER Photograph a formula from paper or a textbook. The app recognises it, shows it in editable form and evaluates it. Recognition runs on your device, offline - the image goes nowhere. MECHANICAL - Gears - ratio, output speed and torque, pitch, tip, root and base circle, centre distance - Machine elements - bolt torque, bearings, shafts - Thermal expansion and ISO 286 fits - Hydraulics - cylinder force and speed ELECTRICAL - Ohm's law from any two values - Series and parallel resistor networks, four-band colour code - Cable and voltage drop - DC, single and three phase, copper or aluminium - RC/RL filters, ADC - Bus timing - Modbus RS485, Profinet, EtherCAT MATHEMATICS - Equations - linear, quadratic with complex roots, 2x2 systems - Vectors and matrices - dot and cross product, determinant, inverse - Function plots and a rotatable 3D surface - Save your own formulas with variables ALSO - Unit converter across eight categories - Material database - metals, plastics, composites - Available in English, Hungarian and German PRIVACY No account, no ads, no analytics, no tracking. All your data stays on your phone. Calculations are indicative. For precise engineering always rely on the relevant standard and the manufacturer's datasheet.

Verdict
RF Tools and EngCalc are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
