Inside the app
A closer look.






About this app
Made for a clear purpose.
Cytomark: FCS Gate Lab is a focused, fully on-device app. A private FCS 2.0-3.1 flow-cytometry viewer with transforms, histograms, bivariate plots, polygon gates, compensation review, populations, and batch statistics.
KEY FEATURES - Open common FCS 2.0, 3.0, and 3.1 event files - Build histogram, density, and bivariate dot plots - Create rectangle, ellipse, and polygon gates - Apply gates across batches and compare populations - Inspect transform and compensation assumptions - Complete bundled sample and local comparison workflow - Local PDF report and Apple system share export - Original offline technical reference library
ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core features and bundled content work offline - Work remains on device unless you deliberately share or export it through an Apple system interface
Research and education only. Gating and compensation choices require qualified review; this app is not a clinical diagnostic or validated regulated system.
