Review summary

RF Calculators app is highly appreciated by RF engineers and hobbyists for its comprehensive range of calculations, usability, and being free of charge. However, several users note common issues such as missing unit conversions (mils to mm), inability to calculate below -10 dBm, erroneous radar range results, and limited antenna calculator options. Despite these drawbacks, users find it very helpful for teaching, system design, and everyday RF engineering tasks.

Pros

Provides a wide range of RF calculation formulas and tools.
Very useful and handy for RF engineers and amateur radio operators.
User-friendly and easy to use interface.
Helpful for teaching and system design.
Free and well-organized application.

Cons

Lack of unit settings, e.g., no option to switch from mils to mm.
Missing important conversions such as mW to dBm and vice versa, especially for values below -10 dBm.
Radar range calculation gives incorrect (negative) results and has formula errors.
Noise figure calculator doesn't accept decimal inputs.
Limited antenna options; users request additions like Yagi, horn, loop, and dipole antennas.

2022-10-07	It*****	The app has good idea, but in RF engineer need mW conversation to dBm and dBm to mWatts. Now you cannot calculate nothing below -10dBm, which is not very useful.

2021-05-03	Ji*****	Good range of calculations. Radar range gives me a negative number, though (2017). 2021: Radar range still gives a negative number, and the formula shown is wrong. I think the quad-root was left out. And answers differ, for equivalent values of dBm's & watts. See wikipedia/Radar. Should not 'Run at Startup'.
