App Description

PEER is an all-in-one EEG recording and ERP analysis App designed for research studies. PEER communicates with wireless EEGs headsets including the new Brain Products X.on (Brain Products.com), and CGX (CGXsystems.com) Quick-20 & Quick-32.

The PEER app collects raw EEG data and EEG data arising from Event-Related Potentials (ERP) neurological studies. The PEER app maintains a collection of "recordings". Each recording has a title and notes which can be searched. PEER displays summary information about the recording (sample rates, sizes, etc.).

The recorded EEG data can be exported in one of a number formats for analysis using MATLAB, BrainVision Analyzer or one of a number of other tools used by neuroscience researchers.

PEER includes Raw EEG recording and display, Visual Oddball (passive, one-response, two-response), one touch ERP analysis, and export to Brain Vision Analyzer or .csv formats.

Additional in-App purchases are now available for:
- Audio Oddball (passive, one-response, two-response)
- N-Back
- Gambling Task
- Posner
- Image Presenter

PEER is not a diagnostic or medical device. PEER is for research use only.
