The present invention relates to a low frequency stimulator control system for a smartphone and a lower frequency stimulator. In a radio low frequency stimulator the operation and status of the low frequency stimulator control system and the low frequency stimulator are confirmed by a smartphone in real time with the Bluetooth function of the smartphone, and fitting information which analyzes information on simulation intensity, stimulation mode, and simulation time of a user is provided, helping the user easily set up and use. According to the present invention, the low frequency stimulator control system for a smartphone and the low frequency stimulator comprise: a low frequency stimulator registration and management unit for searching and registering a low frequency stimulator, receiving data from the low frequency stimulator, and setting an operating environment； a low frequency stimulator stimulation intensity unit for adjusting the stimulation intensity of the low frequency stimulator； a low frequency stimulator stimulation mode unit for regulating a stimulation mode of the low frequency stimulator； a low frequency stimulator stimulation time unit for adjusting a stimulation time of the low frequency stimulator； and a low frequency stimulator fitting unit for analyzing the information on the stimulation intensity, the stimulation mode, and the stimulation time of the user, calculating a fitting value, and transmitting the calculated fitting value to the low frequency stimulator control system, wherein a stimulation unit is formed inside an outer frame and a lid having a PCB and a battery inside and a switch, a display panel, and an LED on one side of an upper part thereof is formed on an upper side of the outer frame. The present invention further comprises a data transmitting and receiving unit for exchanging data with the low frequency stimulator by using Bluetooth to exchange the data with the low frequency stimulator and control the low frequency stimulato
