## What is Theta?

Application displays data from Theta-Meter devices (Wi-Fi and Bluetooth 4.0BLE connection) which measures human body galvanic skin response.

Skin conductance, also known as galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR) or skin conductance level (SCL), is a method of measuring the electrical conductance of the skin.

## Key features

- Galvanic skin response measurement
- Wi-Fi connectivity
- Bluetooth 4.0BLE connection

### 5/5 — A 21st Century tool that allows us to keep the tech alive and relevant!

*2016-08-31*

This app in combination with the Bluetooth Theta-Meter solo can are an excellent tool.

The reads are accurate and fast, and the needle movement looks great. The TA counter works very well and the motion detector helps eliminate reads created by bodily movement.

It is very nice to have my meter with me wherever I go and to be able to connect it wirelessly to my iPhone!
