biosync synchronizes eye tracking, physiology, EEG/fNIRS, facial expression and voice into a single, event-locked recording — every sensor on one shared timeline. Design your study, run it, and analyze the results, all in one app.
macOS & Windows · free for 30 days, then an annual subscription
biosync is self-contained. You design the study, record every sensor on one clock, and analyze the results, all in the same program.
Every step happens inside biosync.
Design the study, calibrate and capture, then analyze and export — every step in a single, friendly desktop app.
Heterogeneous sensors recorded on one clock via Lab Streaming Layer, with autosave, missing-stream detection and gap logging.
12-point calibration, live gaze cursor, I-VT fixations & saccades, AOIs, heatmaps and scanpaths — on hardware trackers or the webcam.
HR/HRV, EDA & SCR, EMG via NeuroKit2; EEG filtering, epoching and ERP via MNE — validated, open methods.
Action units and valence/arousal with py-feat; loudness, pitch and transcripts with openSMILE and Whisper — offline, no per-seat fees.
Drag-and-drop blocks and trials. Upload your own images and videos. Surveys, websites, text — nested, randomized, event-locked.
Per-session and group dashboards, timeline replay with screen video, gaze maps on the real stimulus, and tidy CSV/R + Excel export.
The home screen opens with this exact path — and a first-login tour that explains every feature.

CSV (R-ready) & Excel.
A 42-device catalog routes each through the right open path — Lab Streaming Layer, BrainFlow, a vendor SDK, or an open ML model.
LSL-tier devices need no extra driver — just point biosync at the stream.
Built on the validated open research stack — open methods, your data in open formats, and nothing locked away behind a vendor.
Self-hosted, self-contained session files (HDF5/XDF), open analyzers, and tidy exports you can take straight into R or Python.
Verify-resolve recording, autosave, and live signal-quality monitoring catch a bad electrode or lost tracker before the session is wasted.
A per-device validation harness checks rate, channels, quality and a known-signal test, and saves a pass/fail report.
A guided first-login tour, drag-and-drop study builder, and a one-command self-test that confirms every subsystem.
Drag, drop, nest, and upload your own stimuli.
Heatmaps & AOIs on the real stimulus.
