Signal Logger

It is an application that measures the radio wave strength of the mobile phone. The radio wave intensity level is measured, and then displayed on the map.

The signal strength level is measured and displayed on the map.

There are 5 levels from "0" to "4", or out of service area.

The level usually matches the number of antenna pictograms. (Some models do not match)

It is possible to measure continuously at regular intervals while moving.

The measurement results are displayed on the map in real time.

The measurement result is saved in a file.

By reading the file, you can reproduce the past measurement results on the map.

You can use Google Maps and Geographical Survey Institute topographic maps as maps.

It can be measured even in sleep mode.

In sleep mode, sleep is released during measurement, but it automatically returns to sleep mode after measurement is completed.

If there are too many points recorded in one file, the memory will be insufficient when displaying the map, and the operation will be slow.

It depends on the terminal, but please try with about 1000 points at first.

The recorded log can also be displayed on a PC using a web browser.
