Compare MBS bonds side-by-side and analyze prepayments like never before

NEW: MBS BOND COMPARISON
Compare two mortgage-backed securities simultaneously with fully configurable parameters. A unified rate slider shows how both bonds respond to interest rate changes, with instant delta calculations for price, yield, WAL, and duration.

REDESIGNED PREPAYMENT ANALYSIS
A streamlined interface brings rate shocks, horizon analysis, and scenario comparisons together in one view. Quick navigation lets you jump between sections, and smarter PSA bounds ensure realistic modeling.

DELTA COMPARISON MODE
New toggle between absolute and percentage changes when comparing rate shock scenarios. See exactly how metrics shift across different rate environments.

ENHANCED ACCESSIBILITY
Comprehensive VoiceOver support throughout the app. Every chart, table, and interactive element now provides rich descriptions, making professional bond analytics accessible to everyone.

FASTER & MORE RELIABLE
Optimized calculations with better memory management. Rate data refreshes intelligently while keeping yield curves current.

Significant redesign on iPad.
Addition of callable fixed-rate bonds.
Initial interactive education functionality.
Bug fixes all over the place.
