Wi-Mark is an android application that compares wi-fi signals reception between devices.
Wi-Mark is the best way to compare Wi-Fi reception between different devices.
Wi-Mark gives a score which can be easily compare and see which device has the better reception.

You can download: Wi-Mark on google play
Wi-Mark gives a score in the form of nadBm, which is easily comparable with other devices. Which ever has the highest nadBm in the exact same environment has the better Wi-Fi reception.

What is nadBm?

nadBm stands for Normalized Aggregate dBm.
dBm is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW).
nadBm is the way to compare the Wi-Fi reception between devices.

How is nadBm calculated?

nadBm is an aggregation of all the network signals of a available Wi-Fi networks.
To each perceived signal a constant is added to normalize the results.
on the normalized sum statistical tools are used to reduce deviation.

How to compare Wi-Fi reception strength between devices?

1. Choose a place to run the Wi-Mark benchmark.
2. All compared devices need to be exactly on the same spot while performing the benchmark.
3. Run the tool on all devices.
4. Whichever device has the highest score has the strongest reception.


There are many things that can affect Wi-Fi reception (temperature, humidity, surrounding objects etc.), make sure you perform the Wi-Mark test on all devices in the exact same environment to ensure correct metrics.
