Ringcross: Tree-Ring Lab

About Ringcross: Tree-Ring Lab

Ringcross is a focused dendrochronology workspace for measuring, aligning, and documenting tree-ring evidence entirely on device.

CROSSDATE WITH EVIDENCE
• Compare a sample radius with multiple master chronologies.
• Search explicit calendar shifts and inspect every candidate.
• Review Pearson correlation, overlap, t score, Gleichläufigkeit, and narrow-ring marker agreement together.
• Accept a candidate only when the evidence supports it.

BUILD THE CHRONOLOGY
• Edit annual ring widths in a dedicated measurement table.
• Import year-and-width or width-only CSV data.
• Detrend series, inspect indexed curves, and compare skeleton plots.
• Combine accepted series into a coverage-aware site chronology.

KEEP THE FIELD RECORD
• Record site, specimen, species, radius, elevation, aspect, and collection notes.
• Preserve the accepted shift and crossdating checklist with the project.
• Export a native PDF evidence packet through the system share sheet.

A complete editable sample is ready at first launch. Projects persist locally, and no account, advertising, subscription, or network service is required.

Ringcross is an analytical aid, not proof of a calendar date. Confirm alignments with adequate overlap, multiple radii, marker years, visual inspection, and accepted dendrochronological practice.
